One of my bro's friends, intermediate weight lifter, about 17 1/2, senior in high school started taking andro a couple weeks ago, last time i talked to him. I don't think he really knows what it is, and doesn't sound like he really knows what he is doing, (has done lil if any research on it). I am natural and i don't know anything about this stuff. Just wondering if there is anything special he should be doing while on it, if he should take anything after he gets off of it, and what are the side effects if he doesn't know what he's doing. Any info would be great.
