This is my input on supplements. 5 years of lifting heavy and taking supplements (celltech, n-large, glutamine, vanadyl sulfate, flax seed oil, fish oil, vitamin B-12, c, e, and 1ad), I have gained 60 pounds of muscle and reached many goals in the weight room. I don't know what worked the most because I have always been on this stack of supplements. Either the supplements gave me the gains or my workouts, eating, and consistency are the reasons for the gains. I do eat 3000 to 4000 calories a day. Really, if you have the heart and determination to get the results you want, you will get them.
