Guys, i had a problem like this in the past, my diet, calorie intake was spot on, on cycle for about 8 weeks , no gainns or nuthing. Kept same diet, run another cycle 5 months later,used different source, and with in 2 weeks i gained 10 lb, i was using omnadren, deca, and d-bol. I agree with all of you that dieting has major importance in weight gaining, but also he needs to make sure his gear is legit.
