  RATING: 5 out of 5

"... It is a very effective pre-workout but I believe it may have more ingredients than they disclose. I've been using it for about a year now and I go to the gym 3-5 days a week depending on my work schedule. Recently my gym shut down because of electrical issues so I haven't been able to work out for about a month now. This is the only product I've been using and now being off it for a month I'm showing signs of gyno..... so I went to the doctors and they believe it is caused by nitraflex. There are no labels saying you need to wean off or take a pct after use or I wouldn't have taken it. So my advise if you plan on using it is that you research a pct (as rediculous as it sounds for a pre-workout) unless you want to take the chance of getting gyno and wasting all the hard work you put into your body."

Nope because it's all natural effects. Even though you are 17 it's fine, but your natural test levels are maxed out so you're probably not even using the extra test up.

This won't get you substantial gains as you say after just 6 weeks - he is on other stuff as well. This will help with your energy for your workout and pumps.

"... I have been actively taking Nitraflex for the past 3 months. I have not taken a break and I am getting the same effects as I did in the beginning. I don't take it on my non-training days and my programming calls for 4 days per week in Gym with 2 of them every other day and 2 of them back to back. Regardless, this is the best pre-sup I have taken since they banned CRAZE. I also just stacked it with GAT Muscle Martini and sipped during Intra phase and recovery seems to be improved. "

Doug   Age: 50

"... What ingredient provides the caffeine? I don't see caffeine listed as an ingredient. Some reviews I've seen note that the reviewer liked the product because it did not contain caffeine and others said they did not like it because it had so much caffeine. Which is it?"


April 13, 2013
response by Nick

There is no caffeine in this supplement, but there is a combination of ingredients to improve your focus, energy and endurance. If you want to get technical, here is the list:

3-Aminopropanoic Acid (As CarnoSyn®), 1,3,7-Trimethyl-1H-Purine-2,6(3H,7H)-Dione, 2-(Dimethylamino) Ethanol, 2-Acetylamino-3-(4-Hydroxyphenyl)-Propanoic Acid, 2-Amino-4-(Ethylcarbamoyl) Butyric Acid, Rauwolscine (Rauvolfia Canescens L. [Leaf And Root])

It shouldn't be an issue unless you have some pre-existing issues? Start off with half the dose and see how you tolerate it. After a week, move to the full dose if things are ok.

Best of luck!

"... Anyone else get rash and tingling for about 5 minutes after taking the recommend dosage? Other than that, I really like the supplement."


April 3, 2013

Yes, it's quite normal. It's the beta-alanine or niacin ingredients that companies add to these products. Nothing to worry about, just helps the pre-workout experience.


November 30, 2013

A rash is not a good thing and I got it after taking the stimulant free tablets, I use the powder form with no issues or bad reactions.

"... I had taken this products for the second month and about to finished my 2nd bottle. Do I need to skip and continue? Any side effects on long term taking this? "


February 4, 2013
response by Jay

This product has not been out for that long so there are no studies on long term effects. But with any supplement, it needs to be cycled so your receptors get a break. Otherwise you're just wasting money as you adapt.

I would suggest 10 weeks on, 4 weeks off.

Child's   Age: 23

"... Hey do u actually have to take a week off when you finish your first container?"


January 10, 2013
response by Mike

With any type of pre-workout supplement, you should generally use it for about 8-10 week with a 4 week break to let your system and receptor recover. Otherwise you just won't get the right results in the long-term.

You don't need anything else with this pre-workout. What I would suggest would be to get a good multivitamin, fish oil and a whey isolate for post workout. You can also add something like XTEND by scivation for during your workouts.

Can not stand benching and feeling like i have to itch my face. I got very focused and felt like i could go for hours without burning out. For people that builds tolerences try doing a cleanse about every 4 to 6 months and when you start taking again you should be able to take recommended dosage and feel the effects like you have never taken it before."

February 2, 2012
response by Paul

This one of the better pre-workout drinks out there.. they don't get enough credit because they don't spam the internet and magazine like the bigger brands do. You seem to have been on most of them. I would strongly suggest you take 3-4 weeks OFF ALL STIMS. Your body is just not responding as well and you are probably taking the max dosages to get any effects right? Bad idea.

So.. take a break from it all.. and then start up on it.

January 16, 2012
response by George

Yes.. most of these pre-workouts are loaded with stimulants so the jittery effect is part of the game. If you are feeling sick to the stomach then I would drop the dosage even lower. But overall in a few days or week you should get used to it and experience the actual benefits instead.

GAT has been around for at least 15 years, and they produce quality products. I have used NitraFLEX this summer and was happy with the results, one of the better pre workout solutions out there.

Dominic   Age: 20

"... What ingredients seperate this from 1MR. i have been taking 1MR for awhile and am looking into trying something new. Hoping this can give me the same or even better energy boost and pump?"


December 16, 2011
response by Jonas

Hi Dominic, personally 1MR is one of the best options if you are strictly looking for energy and pump. It doesn't really hold any ingredients to help you recovery, grow, etc. Nitroflex on the other hands claims to have added a testosterone booster, which if works, will surely help you make better progress.

Personally I would suggest to simply add in a bcaa product such as XTEND while you train or even sizeon.. this will actually feed your muscles with ingredients that make results after the pump and energy are gone.

September 8, 2011
response by Jeff

Feel free to browse the results here to get your answer. I can tell you that I have been using it and I really do like it - the label claims that it has testosterone boosting ingredients as well but it's too soon for me to notice that. I have been using it for about 2 weeks, so for about 8 workouts and I do get a great pump and more strength / energy. I have been recovering faster as well for what it's worth.

I would suggest it.. but then again there are a ton of other great pre-workout supplements out there as well. The best way to find out is to try a few and see which works best for you. I personally am going to try the new Neurocore from muscletech next, reading some great reviews on taht.

"... Excellent! Bought this after reading up on it here and in a muscle mag. Seemed interesting as it claims to contain testosterone boosting ingredients along with being a pre-workout shake. Decided why not and have been using it for the past month. Overall I am very impressed. The pumps and mental boost is comparable to 1MR but the big difference for me that sold me is that I actually am getting stronger and have put on some new size, about 7lbs worth. I am sure some is water, etc but my muscles are fuller and I have been getting asked what I am on as the results I guess are more visible than I thought. Either way, excellent product, well priced and I do suggest it if you want to switch up from your current pre-workout powder for a different angle and some more substantial results over just a good pump at the gym. - Nick"

None. It is a natural supplement that does increase your testosterone levels but not to the extent that you will have those side-effects you mentioned. Train hard, eat well and you will see excellent results from NitraFLEX.
