"... This is my first time.taking this produc I keep hearing nice things about it and I'm pretty excited do y'all have any suggestions for a first timer on getting good results"

response by Adrian

Just follow the directions, keep your protein intake high, train hard 4-6 days a week, get 8-10 hours of sleep per night so you can actually make gains, etc.

"... So I have low T, I get 200MG of CYP. every 2 weeks. On top of takin 5mg of androgel evry other day. Can I use this product while doing this. Also I have had virtually no workouts at all. I plan on starting soon. I am 6ft 200lbs, about 3 months ago I was 225, but with portion control, and a little excercising I cut weight pretty easily. I am 30, have 3 kids very busy hardly have time for anything, let alone a good 1-2 hour workout every other day. I want to bulk up a bit, get more defined, can I achieve this by using these products together.....Thanks"

Yes you can stack it together. But your best bet would be to get off your butt and start working out finally.. as pills can't do the work as magic right?

Yea dude im 16 years old, i asked my doctor and med science teacher about this stuff, they both looked into it and all the ingredients and cant find anything bad about it, even the guys at the gnc places said its pretty safe, just make sure u have an intense workout schedule and follow the rules on the box, i consider trying P90X with it im ripped as hell, and havent worked out in 3 months , just started again on sunday and feeling good

OZ   Age: 37

"... Hi everybody.. I am thinking of starting a box of HSP Active. But I take a protein drink about 45 minutes before a workout and immediately afterwards. I eat about every 3 hours.

As far as using it the only time I can take it is in the middle of the night. That is the only time I have not eaten for two hours before and will not be eating it afterwards until the morning.

Has anyone used this product this way ?

I weight 220 lbs with 12% fat level. Want to cut up a little and out on another 10 pounds of muscle by spring. Any recommendation ?

Happy lifting to all.."

response by Hi Def

Ive been using this supplement the exact way you described> My caloric intake is around 3500 and ill be damned if i have to try to cram all that in on a day if I have to not eat for 4 hours of it. It works beautifully. My repair process is far beyond what I had ever expected. You have to make sure to take your workout to failure though. YOu need to signal some shock that would require a lot of repair on your system to make sure it does what it does to the fullest. The only downside I have with it is that you cant take caffeine within 4 hours (I think, might be 6). I am heavily stimulant dependant in the early hoursa of my day, which are around 4am because of a job I have opening a gym. But other than that, I would give this product 2 thumbs up.

"... Just wake up 2 hours before you would normally wake up, take two tabs, and then go back to sleep. Because the active ingredient that causes increased protein synthesis will attach itself to any fiber that you eat rendering it "non bio available" meaning your body doesn't have the enzymes necessary to break it down and utilize it.

"... hey spencer, do you have a link where they talk about stacking with test and bcaa's? i would love to read about it. im having a hard time finding such stacking results by myself. thanks!!!"

naw man but its easy to find that out just research it online its all there.

Hey guy's just to let you all know you can actually purchase a Tex-oe supplement at 1/4th the cost as MRI's price. A company called Source Natural sell's a product called Nopal Endurance which has the same exact patented Tex-oe; Prickly pear extract. For a bottle of 30 caps 10 bucks!!! Dont get me wrong MRI makes great products but your all getting robbed. Check it out for yourself, do a little research and save yourself some money in this rough economy.

"... As far as test goes HSP Active is not hormonal but it does help block cortisol by flushing out the dead proteins so it would be good to stack it with a test supplement, and BCAA;s are perfect to take with it because the book actually suggests glutamine and bcaa's after workout while on it because your body will need more as there are more hsp's working in the body to repair itself."

"... I have taken it for a month and have gained probably 6 pounds of lean muscle so something is working. However i have some questions after reading the book that maybe some of you could help me with.

So if HSP helps testosterone win the war against Cortisol, would it be logical to take a testosterone supplement?

Would taking a BCAA supplement help with the 72 hours that HSP Active works.

"... AMAZING!! I'm from down under (Australia) and we hardly get any good stuff.. Finally something that works! I was very sceptical at first but these are my results.. Dropped fat and looking more defined but the scales have increased. Feeling very warm when taken and during training. Endurance has increased and still feeling energetic post training. Smaller connective muscles usually sore have been completely repaired and feel elastic, strong and loose. This is my favourite.. Recovery is through the roof!! Failure upon failure with drop sets, sepersets, X-reps etc is leaving me fuller and harder yet not tearing with pain with every movement. Fully recovering almost 2 days earlier than before! Love the product!!!

"... ive been taking hsp for a few weeks now and it has made a pretty big diff in my program. im getting alot stronger and ive been putting on weight to, and not sloppy weight. i havent been sweating as much as everyone else says but i would have to say if your going to try a product and you want results then take this."

"... Spindle it might have not workout becuase you are supposed to take it without having any fiber containing foods or products within two hours before and after in order to work consistently, and obviously have a good protein shake after to help repair the hsps, you should be drinking a lot of water and eating good food too, trust me it works well if you take it right my friend is on it and loves it and he takes it as directed, call the company they will prolly be able to pin point where you are going wrong."

"... Spindle- Iím thinking Iím with you. Iíve been taking 3 tabs every other day and have finished my first 3 weeks. Sweating is the common one for me. Not sure Iím seeing any serious image effects at this point. I did go ahead and buy my second box and was going to continue to give it an honest try. No strength increase, no vascularity increase, not much of anything except a dripping wet shirt when Iím done. My protein intake per grams per day has been averaging around 300. Iíll keep you posted.

"... Just placed my order.. really pumped about trying this out. From the literature on heat shock activation of proteins this seems to be really exciting. Anyways, I'll post back full updates when it arrives!

Previous experience with MRI products is the Black Powder and MRI WAR items.. which have really helped with the workouts over the past month or so."

"... DAMN! Works.. and works well!!! I've also tried the muscletech HSP product and it's nothing compared to the MRI version, and that's my personal opinion. I am also stacking WAR for post workout with good results.

Overall.. I think HSP is the next big thing.. along the lines of creatine when it was first discovered."

"... They say by the end of the bottle is when the effects really start i would finish it up if you like the results get a second one, if not stop it. But as with all mri products its usually the second bottle after it fully loads where the crazy results come."

"... I just purchased HSP Active yesterday and took my first dose as I went to bed on an empty stomach (3 caps). I will keep you all posted on my results as well. I am a huge fan of MRI products and they are the only supplement company I will support outside of your protein powders, multi-vitamins, etc. I have been taking NO2Black, CE2 Hi-Def and Black Powder for 3 months now and have seen substantial results. MRI's products are very good. I find most of them to be snake pee and always apprehensive when I buy them. Tonight will be my first workout with the HSP Active in my system so as mentioned beforeÖÖÖÖI will keep you all posted as I move forward. On a side note- MRIís product specialist are very knowledgeable, no sales pressure or hype and usually provide value when you talk with them. "

It has increased my appetite, gave me a better pump and is slightly helping with my recovery ive only had 2 workouts with it so far. I also sweat alot more with it "

"... Dosing is up to the individual. You can take 2 in the morning, 2 at night, 1 in the morning/1 at night. I personally take 1 in the morning/1 at night every other day. The research on this product is VERY promising with over 100 different research articles and science behind how it works in the body which back up the claims. It has nothing to do with hormones and is involved in protein synthesis. The functional proteins in your blood are what act as the transportation system of the amino acids to the muscle tissue to be utilized. What prickly pear extract does is excite these functional proteins to perform this process VERY rapidly allowing for faster and more efficient utilization of the dietary amino acids. This results in increased growth and repair of muscle tissue and also since your body is composed primarily of protein also helps in proper cell development and immune system function. This product is going to be huge for the individuals who aren't into messing with T-enhancers. "

"... In the literature I have from inside the package it actually says 1 1/2 to 2 hours before training, and on off days at night two hours after last meal OR in the morning 2 hours before first meal. The reason is that fiber inhibits absorption of Tex-OE."

"... I agree man, I'm pysched too. When MRI says you'll get results you will, and they don't ridiculously hyperbole their products like MuscleTech. Not all of their products are A+ class, but at least most are quality (Black Powder, Anabolic Switch). Anyway can't wait for it."

"... FINALLY! I've been seeing the ads in the magazine for the past few months talking about something new from MRI. This sounds extremely promising to say the least. I am currently on black powder and war and it's, in my case, the best pre and post workout combo to date. I've tried Gaspari, BSN, MHP, Muscletech, MAP.. MRI is the one that works the best for me.

Really psyched about this one.. let's bring it on baby!"
