Took the stuff for about 3 months and it did not give me the shits as bad as regular protein but it was a lot more expensive. I did noticed that it made me sleep better and my body fat went down. My weight went up, added about 5 lbs of muscle during the 3 months. This may not sound like much but for a hardgainer like me, it was a lot of muscle to add. After about 2.5 months my weight was staying constant so i decided to switch back to a cheaper protein. Maybe now will be a good time to try it again, seeing how its been nearly a year since taking it. Another reason for quiting was due to the fact that it increases your IGF levels and according to a few articles, you are increasing your risk for prostrate cancel. However the lastest research indicates there is no link between the two.
