This stuff works EXTREMELY well. Started at 1 pill a day and I noticed the effects on my pumps immediately. Ran it like that for about 10days then stepped up to 2 pills a day and I noticed a strength gains almost immediately as well. I'm coming off of cancer, been in remission for 2+yrs now, and I'm really glad my Dr. Said I could take these. My wife has noticed a change in my body composition. I'm not saying it's a miracle drug but in my humble opinion it's way better than NO2 or creatine. I have been recommending this supp.to everyone that's asked what I'm taking. I can't wait to try TurkBuilder ! 10 out of 10 would recommend
