Alright then.....I'm 16 years old, and I'm 6'2", and 170 lbs. I'm a hard gainer though. With enough talking to my parents and enough dedication to show them that I'm not giving up on this they finally gave me the freedom to buy what supplements I want. So I figured since I'm a hard gainer, and I read in Arnold Schwarzeneggers encyclopedia to modern day bodybuilding that weight gainers are great for people like me, so I went and bought a weight gainer at GNC. It gives me 2200 calories a serving with 48g of protein in each serving. So I drank one of those the other day and it was definatly different, but I can get used to it every now and then. I also bought some creatine though. I get 5 grams of creatine monohydrate each serving. Now I've only been on the creatine for 1 week, and I only had 1 serving of the weight gainer (like I said before). But this morning I looked at myself in the mirror and was flexing and making my pecs bounce. The stuff really seems to be doing good for muscle MASS. I also noticed though that all of the veins I DID have are now covered up again. Even when I flex, I only get 1 TINY glimpse of a vein in my bicep where it used to be very defined. Now is this problem from the weight gainer (1 serving) or the creatine for a week? If I continue with the creatine will I get definition back? is this just the begining stage? thanx
