I did not see any gains from this product. Was very strict about not taking fiber(which sucked, especially when wiping my ass).. Despite dilgence in following the products protocl I rarely saw an abnormal pump and certainly no great increases in strength or stamina in the gym. I know friends who have tried it and had the same negative results. I do see people here have postive results. But from my experience this prodcut is a waste of money.

I got this BOGO from BB.Com. I just started my second month on this, and so far, absolutely no result. I followed the suggested protocol to a "T" (which aint easy) and have seen nada from this crap. I use to have alot of respect for MRI, but after this, I put them in the same catagory as MuscleTech. (Outrageous claims and promises, with absolutely no beneficial results)

I rated this product with 10s across the board because it did exactly what MRI said it would do and because I made great gains in recovery strength and size. Basically if it didn’t work for you it’s because YOU did something wrong. It's that solid. How many supplements can you say that about?

The first day I started taking hsp, in the middle of the night I got so hungry I had to get up and eat( was hungry all the time). My arms were pumped all the time even chores around the house I could feel my arms geting pumped. It was nice to only take every 2 days. A bit pricy but seemed to work.

the product was good. The first day i took it i had a great apetite. I noticed after i finished my first box i gained 8 pounds and 20 pounds on bench. It was easy to take and worked well. try to get ot on a bogo day if so great choice. Stack it with amplified wheyabolic extreme 60. This mix worked for me.

I read the book and learned about "perfect Protein" so i bought it. I def. helped with my strength but MAKES U TOO DAMN hungry and my metablosim is fast enough. But then when i got another box again it beileve i became too tolerant and the dosing is a pain ass cause u can't eat fiber for 4 hours AND U NEED FIBER!!! and by the time you train your too hungry but you sweat a lot alsoa nd body temp goes up a lil bit. Not worth it though get Prime more bang for your buck (thumbs up)

great product. took one box and i loved it. yes it makes you hungry all the time but thats just your body telling you it needs more fuel. if you eat more on this product you will deffinately gain mass and recover quickly. dont down the product because you used it incorrectly and didnt eat enough with it.

I'm currently on my 5th box of HSP Active and I will say that it has been working wonderfully for me.
Advanced and ever intermediate lifters who depend somewhat on protien shakes to supplement their intake daily know what I mean by one works better than the other.
If you have used a lower quality protien in contrast to a higher quaility one, you can tell the difference. This is the situation with HSP Active. Taking only 100% Whey from GNC in the duration with my first 2 boxes, (I've taken high quality protien since and have only noticed increased gains) I can honestly say that I can TELL the difference. Mostly I've prominently seen the rapid rate at which my progess has sped up. taken it 2 hours after my last meal of the day and I've noticed the sweating more during training sessions but not so much the hunger pangs. Not an issue to insure doses, unless you eat late at night. The main Pro with this supplement is A.) It (with proper and timed dosing) will increase your gains (Which it's main focus is. Period.) and B.) You don't have to cycle the product (MRI claims) which means you can achieve optimal protien intake 24/7. The con's: A.) Most lifters/ahletes will not enjoy this product due to lack of physical/mental immediate changes (i.e Pre-Workouts) B.) Price is high-ish to doses in atleast heavier lifters only a couple week supply if 200 lbs. +.
Overall, MRI HSP Active is a wonderfully designed product but only if you're truly content on seeing protien content intake becoming maximal. Best part is gains become more and more apparent with extended use. Highly reccomend this product if patience is high and product is affordable.

on my 2nd box and im starting to notice some big changes. i didn't notice anything on the first box, but i bought 2 boxes BOGO at GNC so i figured i might as well use it. i had to increase my protein intake because of this product because i would get super hungry, especially after my workout. i can literally feel my muscles sucking up protein and turning it into muscle. it's almost like little iron workers welding new muscle on. my recovery went through the roof, and im noticing some pretty strong gains. also taking, massive weight gainer, Anabolic Pump, PowerFULL, pro nos, Mega Men Sport, and about 3g of Fish Oil daily. i saw good results before i started this product and noticed better results with this product so i would recommend it.

Didn't notice anything other than I was hungry all the time. I pushed myself more when using this then I had before. Noticed a little gain. Eat more + work harder = gain don't see where this added to the equation.
