D1 D2 have round year testing at random...but chances of getting tested are slim and easy to cheat...me being a former D1 AA football athlete while juicing..at 195lbs he will NEVER see the field at linebacker being that he would have to be around 220lbs to shed a blocker and stuff a hole..at Running back on the offensive side of the ball a good wieght for him would be 200lbs to 210lbs..he is 5' 11" so he will maintain speed but also and more importantly be more durible cause trust me RBs take a lot of punishment..and even at 210 he will be considered a medium to small running back for a division 1 level...also most people get caught in college by leaking out what they are doing like tell their buds tha they are juicing etc..in the college level having a redbull b4 a game is banned by NCAA for to much caffine levels..and most LEGAL suppliments are banned by the NCAA so the most important thing to do if this is a road he wants to take is to A. tell NO ONE waht he is doing...B. dont make inject spots obvious as itll rise suspition and C. cycle on certain AAS that has shorter times of exiting the body... GOOD LUCK and i wish u and ur nephew luck with this process...i hope my info was helpful..
