"... omg, Some people are so much like a cry baby's and don't have a clew or know what thermogenic pill even mean and what it does. I was 300lbs. now I80lbs. and lost it all. I never had a thermogenic pill in my life then thought one day will try them I try it and weights started coming off. I try these kick ass thermogenic and I love these and yes these are going to make you sweat that's part of losing weight."

"... I have never been allergic to anything & I thought I was going to DIE!!! My skin broke out in a red burning rash. I was extremely scared. I am a very active healthy person & these diet pills were horrible. PLEASE do not use. I have taking other supplements before and this is the worst reaction I have ever experienced. I almost went to the hospital I was so scared. Can't believe there's products like this on the market. Extremely disappointed."

"... I have completed my first bottle of this product. Admittedly, I do get the desired energy. However, I have yet to feel any other benefits. I eat clean (probably could do better in this area and eat MORE clean foods). I exercise 5 to 6 days a week (cardio, strength training, stairs etc). I have not experienced a decrease in my weight. My goal was to be on this supplement for 60 days to lose to 10 pounds. I am disappointed I have yet to see results. With that said, I bought 2 boxes (a sale buy 1 and get 1/2 off), thus, I will continue with the 2nd box to see if it renders better results. Please advise if you have suggestions/comments/solutions."

"... I'm used to taking diet pills. However I've been caffeine free for two months due to migraines I took one dose of this yesterday and I think I had a case of caffeine over dose. Sweaty dizzy heart racing nauseous vomiting a lot of diarrhea stomach cramps. Worst experience ever. But I think it was me being caffeine free. "

"... I am currently on day 2 of this product. So far no bad side effect. Just the normal flush and redness associated with taking niacin which lasts about 20 minutes. I am utterly dumbfounded at these review saying the redness is an allergic reaction. Hives are an allergic reaction. The redness is a normal reaction to niacin. It can be reduced by taking an ibuprofen or Advil with the pill. Read and research about niacin supplements in general and the reactions they cause before you down a product and call it an allergic reaction. Wow! "

"... I walked into GNC two weeks ago looking for a completely different supplement… Unfortunately, they didn't have it and the [completely WIRED] sales guy recommended this product. Let's just say that I've never been so afraid in my life after my first dosage. My face swelled, body was on fire and heart was racing. 45 minutes later, my entire body is slightly swollen and blotchy - and to top it off, I don't feel the rush of energy I was expecting. After the first time it happened, I called GNC asking if anyone else had complained about the same or a similar situation and the [wired] sales guy said no, in fact, that he was up to two dexys a day; he then proceeded to suggest I take it with food… I did, and had the same results. By no means am I sensitive to caffeine or caffeine products, but THIS is BY FAR the worst supplement I've ever taken - and this comes from a woman who lost over 100lbs with a little help from a few "friends" (thermogenics).

Don't do it! "

"... I started this product May 14th and I love it!! I was told by the woman at GNC to eat something first because it can upset ur stomach if u take it without some food so that is what I did I had a healthy breakfast and took the two pill about 45 min later. I did feel a little warm but I have taken oxy elite pro before so I was used to that feeling. I was a little worried taking this product after reading some of the reviews but the only way I would know the affect it had on me was to try it. I then took the one diet pill in the afternoon I had energy all day no shakes or jitters or rashes nothing. I love this product so far I have lost 65 lbs over the past year and just needed something to help me lose the last ten and to lean out a bit. I work out 5 to 6 days a week I eat healthy and I am muscular and toned so I just needed something to help break me thru thus plateau. Definitely going to keep using this for the eight weeks and see what happens if u have used oxy elite pro before this is pretty much the same. I love it!!!! "

"... I had been taking this product for about a week and yesterday after taking it while I was eating I felt super hot! It felt as if my ears were burning off. The previous day my mouth was burning but I thought it was just because I hadn't eaten anything so I ate and it went away.. This time I went outside and still felt hot. I walked to my room and shut the door because I didn't want to freak everyone out. I looked at myself in the mirror and when I took my shirt off my whole upper part of my body was hot, red and covered in bumps. Not to mention very itchy. My knees, elbows and knuckles were also very red. After an hr it went away but I called the hospital and they said to stop taking it. I also took it this morning and jumped into the shower just in case it happened again and it did. It already went away but it's scary when it happens. I really want to keep taking these because it does do the things it says it's suppose to do. I feel like it also helping me lose weight. How do I do this without having this happen to me? After reading over the reviews it seems like I'm not the only one this happens to.. If I were to take it back would I be able to get a refund?"

I have never had an allergic reaction to anything but realise this product seems to bring out the worst in my body. Be careful, I feel like I'm on speed (yet have never taken any illegal drugs before). I can see how some people would have to head down to the hospital after taking this pill. Very scary experience... :( "

"... I purchased this and plan to take a cycle. For anyone reading this and/or considering taking; all of the negative side affects mentioned are normal reaction to the ingredient Niacin. Some may be allergic but most likely it because they have never taken. I have been a trainer for over 15 years and have a degree in the Feild of nutrition and fitness. Niacin in medium to moderate doses will cause nause redness and itchy skin. It usually goes away once the body adjust, for those who have never taken any form of niacin it is almost certain you will get this reaction at first from any supplement containing the ingredient, just thought I would share that information. As for the hospitalization review, though not likely any one can have an allergic reaction to something it could be any one ingredient it's almost impossible to know everything your body is allergic to until we encounter the allergy. That doesn't make a bad product just helps to realize something in there is causing an allergy. Best to get allergy test to find out what ingredient it may have been to try and avoid in the future. Also the mother posting the review said it was her son so a fair assumption is he was under 18, if that is the case it should have never been taken supplements are not usually intended for kids and can be unsafe."

I know to take Dexyfen in the morning, but D.I.E.T. suggests to take one in the morning and one in the evening. Is it best to wait a while, say 2 or 3 hrs, before I take the first dose of D.I.E.T. or just take the 2 together."

I noticed that whenever I take them my I get a red rash on my upper body and itching like hell with little red rashes. I've taking other appetite suppressant supplements before and have never had any reaction like this. I'm taking it back to GNC today for a refund. I would not advise or recommend this for purchase to anyone or if you're going to purchase it then do research on the side effects first. "

"... Within 15 minutes of taking this my skin and face started turning red and burning. I took Benadryl and it helped a little but still was burning, itching and swelling to skin. I induced vomiting and took another dose of Benadryl. I thought I was going to have to go to the ER. Finally after about two hours it started to subside. I still had the redness for a total of 3 to 4 hours and didn't feel good the rest of the day. The only other time I have ever had anything close to this was when I had used a tanning lotion about 8 years before this that had a pepper in it, I believe it was capscium or capsaicin I’m not sure exactly which ingredient. But it did almost exactly the same thing to my skin. I will definitely NOT be taking this again! I would suggest that if anyone has EVER had any sensitivity to pepper to avoid taking this product."

I would take the D.I.E.T pill mid-morning, and the Dexyfen when you wake up. If the dexyfen is too powerful, try breaking it in half, or consuming it with breakfast.

"... Only take half of a pill. This is too strong of a dose for most people. Their is a stong menthol sensation that stays in your throat and chest for a couple of hours. Enough to make you nausated. They need to make this in a weaker dose. It does work well for a appetite suppressant. Increased heart rate too. "

"... I have been using this product with my friend for about 3 weeks now. Do not drink coffee before or right after you take it!! If you take it with lots of water you will feel energized but may feel a cold sensation in your stomach.
My friend feels sick when she takes it and sometimes throws up after. That has happened twice. I on the other hand usually have to use the bathroom about 20 minutes after and then have energy all day. For some reason the past couple of days the pill has made me very shakey and I have uncontrollable sweating and I feel like im going out of my mind. I had pains in my side this morning and too much energy combined with sweating and being scared I almost went to the hospital but decided to move around and release some of the energy and felt better after but still sweating a lot. Good pills just sometimes bad side effects"

"... Really surprised by some of the negative recent reviews, the last two sound very much like the same person. Anyways, I've been using this for nearly two months and really do love it. I take my one capsule first thing in the morning on an empty stomach with a full glass of water and then do my 15 minute cardio. I have a treadmill at home so that makes it easier. I then have my breakfast and get going with my day. No need for coffee anymore as the energy and focus is great and lasts to early mid-afternoon. In the time since I've started using this I am down 12 pounds, which comes out to roughly 1-2 pounds per week.

Highly recommend it and I will continue to use it."

I purchased this product before reading the review, i wanted a weight loss/appetite suppressant product that would give me energy and help me with my inability to do portion control lol. i used oxyelite pro a two years ago and it worked, i decided to use a different product because i hated the fact that i needed two pills daily in order to get the maximum effect of oxyelite pro and at that time i had a personal trainer. Two years, later i have a baby, no personal trainer and i have a sedentary lifestyle. i weight 158lbs, and is 5'4. i took one Dexyfen, the capsule is gigantic, i have a weird feeling in my throat its mild,yet annoying. i took the pill at 7am , its 12noon no change except that weird feeling in my throat, its uncomfortable. i also took women's ultra mega active packet it was suggested by the GNC representative. i will continue to use this pill for one week, if this discomfort does not go away i will go back to oxyelite pro"

I hope it's just the first days that cause reaction.I hope these pills show improvement because if rash continues I will return products to GNC. I was really excited about product after speaking to GNC Rep. I'm going to give it a couple more days hopefully I see no more reaction don't consider quite dangerous but it is a small concern be careful.

"... I'm on day 12 of taking the dexyfen and I can honestly say, I've never felt better taking any supplement. Apparently everyone with the negative reviews either have some type of pre-existing condition being triggered by the wrath of this stuff, or,no offense, is a little turd and can't handle it. It gave me the boost I need early in the AM(working 7 days a week, 12 hour days, I need a good bit.) no jitters or redness. I've taken plenty pre's and caffeine sups and got immuned to them quick. I don't see this stuff wearing off anytime soon. I'd recommend it to anyone, just start off slow and build a tolerance. Stay hydrated too. Oh, by the way, I've lost about 14 lbs since my first pill but, I'm balls to the wall all day. I kinda expected a little help would shed some weight quick. I hope this helps y'all. "

"... Just an update. I am currently on day 3. I decided to take the entire pill since yesterday I felt just fine. Good news is I was down 3.2 pounds after taking it just 2 days. Day 1: took half the pill in order to avoid side effects and adjust, no weighted work out or cardio, Day 2: Took 3/4 pill, no side effects also did just 1 hour heavy weight lifting, upper body (due to broken foot). Energy levels were good both days, appetite was suppressed. Day 3: took entire pill, weighed in with a 3.2 lb loss. Approximately 40 minutes after taking the pill I got really hot feeling and noticed a burning red rash on my upper body. I decided to take two benedryl. It went away fairly quickly. I feel fine now. Doesn't cause any jitters! I will stick it out and see how it goes. I do think that some people may panic when getting the red rash and therfore they think they might die. However, I tend to break out in rashes from allergies any way. If you are looking for weightloss then I would give this pill a try! (along with benedryl on hand of course). "

"... This product was recommended by a GNC employee. I weight train heavy 4 days a week and was doing cardio 6 days a week until I recently broke my foot. I am trying to break a plateau and plan on using this supplement while I can no longer do cardio for 3-4 weeks. Day 1 I emptied the pill to about 50% full to avoid some of the scary side effects and see how I react. I could feel it working until about mid day. It curbed my appetite. I ate just what I needed to keep my protein/calorie intake, but I didn't feel hungry. I was slightly jittery for about 1 hour. Not bad though. I took it on an empty stomach, ate 30 minutes later. Day 2 I emptied the pill to 3/4 full. Not jittery today and no rash. I did get the icy/hot feeling in my throat for about 20 minutes. It was fine though. Tomorrow, day 3, I will do 3/4 and then move to full pill on day 4. I have made sure to drink 8 glasses of water as recommended by the GNC worker. So far no weight loss but I will keep you updated.

No, it is meant to be taken FIRST THING in the morning on an EMPTY STOMACH. The directions are very specific for a reason, because that is how the product works best.

It doesn't matter if you take it BEFORE, DURING or AFTER your workout as that is not what the product is made for.

I gently squeezed around the seal of the pill and pulled the top while twisting slowly for a minute or so. This separated the pill so that I could dump part of the powder out.

I was worried after reading all of the reviews that it might be a bit too much all at once. So yesterday I dumped half the pill. I could feel the caffeine feeling until mid day or so. Today I dumped 1/4 of the pill. I feel pretty good on it today and I will do the same thing tomorrow and then by day 4 or 5 I will take the entire pill. I didn't want to shock my body with drastic intake to quickly. So far so good.

For those having mini-panic attacks and thinking they were near "death" lol, it's just a stimulant and the itchy/redness is a NORMAL reaction that goes away. Welcome to supplements in the year 2013. If you have any issues or can't handle the effects, then by all means cut your dose back but please don't think your life is going to end lol."

You need to allow your body and receptors to recover and get back to normal, otherwise they will burn out. I would suggest 8-10 weeks on followed by 4-6 weeks off.

"... My son (age 23) was just admitted for hospitalization after having convulsions and muscle spasms from this that were so overwhelming he could not speak nor control any of his muscles. Furthermore, his heart rate was 177 when they hooked him up to the EKG, the doctor said he had anxiety as well, which made it nearly impossible for him to focus on controlling his breathing. It was horrifying for me as his parent to see him wrangling, deformed and helpless. He was released to bed rest with the warning that he had basically lost about 1/3 of every muscle cell in his body due to the extreme stress his muscles went through. His doctor submitted and FDA report, and recommended seeking legal counsel. "

Yes, you can take what you feel comfortable with. It may be too strong so it's always best to test your reaction first.

January 20, 2013
response by Carl

That's because it's a very high and strong stimlant. Did you start off at the LOWEST dose and slowly work up or did you jump right to the highest dose? Also, did you take it close to bedtime? If so, of course it will keep you up it's a very potent stimulant.

Go back to the low dose, let your body adjust and never take it within 6 hours of sleep.

"... Day 2 using dexyphen. I should have refrained from reading all the reviews as most of them relay near death scares, shortness of breath, vomiting, rashes and countless other heinous side effects. I have not experiences them to that degree but I can tell you that day two is enough for me me. Im anxious uncomfortable queezy and i cant believe people would post on here all their horrible stories and end with "I will try it for a while longer to see if they subside!" come on perople! your body is telling you something LISTEN! After reading over 20 reviews about people thinking they were going to have to call 911, and assessing how I feel right now I can say confidently that someone will likely kill themselves on this product. The unfortunate thing is that it will take such a tragedy before it is taken off the market. Its interesting that the product has an overall 3 out of 5 rating. i wonder if it is the string of 5 out of 5 ratings at the bottom of this page...I also wonder why, when the product has been so unanimously trashed that there was this string of individuals that thought it was just the greatest thing ever. Im calling bull, and whatever company that group of people works for should be shut down. BAD PRODUCT WORSE SIDE EFFECTS FIGURE IT OUT!"

There is 30 mg of niacin in dexyfin. I react poorly to products with large amounts of niacin. Sounds like you do as well. There is no way to take a lower dose of this product as it only comes in one dosage size. If you cut the pill then you end up with a horrible tasting substance the burns your stomach up. There are other products on the market that don't contain Niacin. Good luck!

"... I took dexyfen for a couple days after taking a Benadryl (like most reviews suggest). Today I decided to try it without the Benadryl and it was literally the worst decision of my life. 20 minutes after I took it I felt a little warm and nauseous. But all the sudden my face turned purple and I couldn't breathe. I couldn't even gather the energy to dial 911. After splashing cold water on my face, I cooled down enough to find the Benadryl. If I had waited, I don't know what would have happened. This product gives me energy and suppresses my appetite IF AND ONLY IF I take the Benadryl first. I plan on remaining to take this under very close watch. But at this point, it's almost worth being heavier over not breathing."

"... Like many others, I received a "sample pack" from GNC with my AMP 60 protein powder. I was about to go to the gym, took the pill on an empty stomach like suggested on the bottle. Within 10 minutes, I had a SEVERE ALLERGIC reaction. Mind you, I have NEVER had an allergic reaction to any submstance or food in my entire life. My face was on fire, swelled, then spread to the rest of my body. Red, burning, swollen, and blotchy skin down to my feet. I was terrified. I tried to throw it up in order to limit the effects, but since I took it on an empty stomach, that was nearly impossible. I was very relieved the side effects were only temporary and lasted a couple of hours, at the most. Most of the burning was gone within the first hour. I don't know what is in this product, but it was an awful experience for myself."

response by George

Glad you are experiencing good results, this is an excellent product. With regards to your diet plan, if you are trying to lose weight you need to cut back calories. Essentially, eat 5-6 small meals per day, 2 of those can be protein or meal replacement shakes. Stick with high protein, medium carb and no fats - except healthy fats such as fish oils. You should exercise or do cardio about 3-4 times per week as well.

"... In the past I used OxyElite Pro and had good results. I only had minor side effects that come with any thermogenic and they only lasted the first few days of a cycle. I went to GNC to get more and since it is being reformulated, the saleperson recommended Dexyfen. I read the reviews and was a little skeptical, but decided to try it. Yesterday I took my first dose and felt fine. I had a little bit of redness in my eye but that only lasted about an hour. Today I took my dose and within 10 minutes experienced horrible redness and rash all over my body, and within 15 minutes left for urgent care because my throat began closing. They gave me a hefty dose of Benodryl. I've never had an allergic reaction to any supplement before and seem to have a pretty good tolerance for the thermogenics. I would highly caution anyone taking this pill, even if you have taken other supplements in the past!"

October 15, 2012
response by Carl

I would not go beyond 8 maybe 10 weeks. The reason is that your body adapts to the to the ingredients and requires a break or it will not burn fat anymore. I suggest cycling with 8 weeks on, 4 weeks off, 8 weeks on, etc.

Always focus on your diet and nutrition at all times.

"... I just finished my bottle of OxyElite Pro. I went into a GNC to buy Lipo 6 Black and the representative got me into Dexyfen ProThermogenic. After reading these reviews, I am thinking the Lipo 6 would have been a safer, more effective pill. With the OxyElite Pro, I take one pill more than the max so I am used to the sweats, jitters, caffeine rush and I know that is part of any effective pill. Anyways, why are there so many allergic reactions if this is such a great pill? Im just nervous about starting it after the reviews. "


October 15, 2012

They pushed the Dexyfen on you because that is more recent and they get a commission, I feel that Lipo 6 Black is a superior product, and OxyElite is also a superior product.

I would call Dexyfen more of a stimulant than a fat burner.

I mixed this pill with a different dietary pill so I figured I had just over did it. I decided to give the pill a try today and this is had my day went. 8:00 am - Bottoms up. 9:00 am - definitely a lot of energy. 12:00pm- just worked out awesome still feel very energized. 1:00pm-- getting sleepy. 2:00pm- really sleepy but still very energized. 3:00 - all I wanna do is fall asleep, but can't way to energized still. 3:00-6:00pm- feeling kinda icky, lot's of water uggghhh body feels way more energized then what it should but I feel so exhausted at the same time. 8:30-Finally my eyelid's are dropping down sleep here I come !!! 10:38(right now)-Sike, guess my body playing tricks on me. Thought I was about to fall asleep but nope two hours later I'm still energized to the MAX, I guess I'll go online and see if this is a normal side effect. Which brings me here writing this lol. PRO:I believe that this product may provide lots of help with weight loss, because it will sure provide the energy to never ever stop working out, all I want to do right now is move around. CON: Is the same as the pro considering the energy is almost to a point of ridiculousness, and the icky felling has yet to go away. I will continue taking the product for the following week, hopefully I will have better comments about the product in the week to come. I would not at all recommend this product to ANYONE sensitive to caffeine."

The next 3 weeks it started to change, I wasn't feeling the energy and my stomach did not agree with the pill, I still had the cool sensation while working out. The last two or so weeks were horrible, I had to eat a snickers bar just to make it through the work out and had no energy. I was puking and couldn't keep my meals down. Turns out I got a stomach ulcer from it all. So I would have to say anybody working out more then 4 days a week with this should have a back up plan or only take it every other day.

What is SuperMax? I assume if it is a pre-workout product then it contains stimulants so mixing it with this will probably to much. However, you may be able to handle it so you can try it and see how it affects you.

Using protein is a MUST regardless of any other supplements, it contains the building block to build and repair muscle.

"... Week 2 and so far so good. I have lost 7 lbs but Dexyfen is not the only thing I am doing. The manager at my neighborhood GNC is the one I always go to for advise. He really sets me up for success. This is the program he put together for me and made sure I understood that if I prioritize things in this order, my goals of weight loss would be much more likely....1. 3 liters of water daily. 2. Mega Men's Performance and Vitality vitamin pack. 3. Exercise at least 3 times per week. 4. 7Day complete bode cleanse. 5. Eat 5 COMPLETE meals per day (I am using the pre-made Lean Shakes for 2 of my meals). 6. Dexyfen once per day.
This may sound like a lot but I can only tell you I am happy with results and the way I feel. A co- work just asked me today what am I doing. He notice I looked a little less full in my face :). The Dexyfen works great for me and I would have to say if you follow this plan, you too will be happy.

All fat burners contain stimulants usually and slightly different ingredients - the best way to find out is to try.

"... To clear any confusion, I have recently worked for GNC and for a period of time we were required to push Image Sports products, so if you were talked into buying this product, it have not been in your best interest. However, I have a lot of experience in the health, nutrition and fitness field with a background in natural and holistic healing. Every body is going to respond differently to each supplement, so, unfortunately you cannot have expectations from reading reviews. OxyElite does not work for me, however, Dexyfen has a stronger effect on my body than anything else I have tried. Appetite suppression is more immediate than long term. But, I force myself to eat within 30 minutes of taking dose. Doing so will decrease stomach irritation and possible nausea. My energy levels are not effected by this product, however, I have a high tolerance to stimulants. Dexyfen is one of the more potent thermogenics on the market, next to RoxyLean, so I rarely suggest this product to people who are new to thermogenics. To maximize your results, I suggest taking at least 3.4grams of CLA (Conjugated Linoleic Acid) a day. Water intake should be at least half your body weight in fluid ounces a day. Do not reduce your calorie intake; the body runs on an average requirement of 2000 calories per day; thusly, focus on your source of calories. It is not recommended to take any other stimulants while taking this product, however, your own tolerance should be assessed; for instance, I DO take 1MR PWO while on this product and I do not have any adverse effects (again, assess your own tolerance). I would not recommend taking more than one pill a day. if you find your body does not respond to the product within two weeks, you may want to consider other options."

Yes, some people react differently to stimulants - you are very sensitive to them. Just the way it goes sometimes. Try cutting the dosage in half.

"... I have been taking this for 3 days and I get a rash and burning face and arms for about an hr in a half, what can I do to stop this or help with it I would like to continue taking it but I'm not sure if it's worth it?? I get soo red and it's burns.. Does it eventually go away?"


April 16, 2012
response by Heather

The rash and "burning" feeling is quite common and a normal reaction to NIACIN. Nothing to be alarmed or worried about.

If it's too much to bare then you'll have to switch products.

April 15, 2012
response by Joel

Everyone has different tolerant levels to stimulants, so this may explain why you are not so sensitive to it at this point. I would not go beyond the directions and use more than one capsule per day.

If you find it too weak, consider something stronger such as Muscletech's Hydroxystim, etc.

"... I am on my second day with this product, and there is no side effects yet. I drink too much water though. I want to just know, do I still have to drink my protein (100% whey)is that OK or not? Or is there some specific recommendation? Thanks. "


April 13, 2012
response by George

You shouldn't experience any side-effects and there really is no such thing as drinking "too much" water, so you're OK.

With regards to drinking protein, yes keep that going. No matter what your goal is, or whether you are even training or not - you need to drink you protein.

"... Hey guys, so OK I am on day 32 of the 56 day cycle and I am fairly impressed. No side-effects to speak of and I have made better progress with my fat loss then before, without it. I will say energy levels are noticeably improved from the first dose. Appetite suppression works pretty well also, as I do find myself less hungry. For those that think appetite suppression means stop craving just junk, think again. That part you need will-power and dedication for. In terms of weight loss, I am down about 11 pounds and my goal is 20. Not sure if I will reach it before the box is empty but I will continue on either way with my diet and cardio classes."

Well from your first day, you are on the right track. Will it aid in fat loss, absolutely. Will you need to put effort in to your exercise and nutrition to see the best gains? Absolutely. This is the case with EVERY fat burner / energy pill.

Good luck and keep up the great work!

April 12, 2012
response by Josef

16oz of water won't do anything for after taste, try something with flavor if it bothers you to get rid of it. I have been using this for about 2 weeks now and can't say I have any after taste at all. Even if I did I wouldn't really care though as I use supplements for the results not flavors.

"... I have taken my second dose of Dexyfen. Drink plenty of water after taking this supplement. If you do not, you will receive a weird taste and you may become nauseated. I have not experienced any other negative side effects. My energy level yesterday was immaculate! I usually have to take afternoon naps from feeling extreme tiredness. I was awake and feeling great until around 11pm. I had no problems falling asleep. During body pump, this morning, I lifted approximately the same amount of weight as normal, although I did feel that I could have increased the weights. Typically I max my weight, then reduce the weight at break intervals. Today I did not reduce the weight amount!
My appetite is up, so I will have to watch my calorie intake more than normal. Usually when eating, I eat till I am full and stop.
I am a huge fan of Oxyelite .I am taking Dexyfen as my Oxyelite break. I think this will be a great experience. I am excited to see a difference in my body size.

April 6, 2012
response by Neil

Did you start with the lowest dosage? Might just be too advanced too fast. I would suggest to lower the dosage and see if that helps. Otherwise you are too sensitive to this product and you'll need to look at other options.

That is the NIACIN component or something similar. If it went away after an hour or so it should be fine. If it bothers you, switch to a different product.

response by Tommy

Just follow the label directions. One capsule in the AM on an empty stomach. Never take more than one a day, it's very advanced.

Oxyelite is a DIFFERENT supplement, so never do what some other pill had you do. All are very different formulas with a different blend of ingredients.

Always follow directions.

My pre workout is GunPowder by Muscle Tech? plz respond as soon as possible. Thanks."


March 26, 2012
response by George

Hmmm.. maybe cut the dose back in half on non-training days? Are you currently taking any other supplements? If so, that may be the reason as even the simplest protein formula's or vitamins can have unknown ingredients that interact.

Do not combine TWO stimulant based products, stick with one.

March 26, 2012
response by Frank

If the rashes go away shortly after each use you are ok. If they are lasting 24 hours a day, 7 days a week then for some reason you are having a reaction to dexyfen, probably in combination with other supplements you are taking. You can also lower the dosages.

"... ZERO rashes, red bumps or anythign the other few people commented on (same person?).

I have been using dexyfen for about 5 week snow and really improved my workout energy and endurance and drive. With weight loss, I am down about 8lbs - but I do exercise 5 days a week and watch what I eat Mondays through Fridays. Mind you though, I didn't change anything in my diet or training before I added the Dexyfen so that is the reason for my weight loss - I am sure of it."
