Tweetget him a trainer early on for sure and maybe a nutritionist (or you can just teach him how to eat) other then that creatine would be the only thing id feel comfortable giving a 15 yr old

TweetGinseng, Brewers Yeast, Vitamins: Multi, E, A, B complex, Plenty of C, Protein as much as he will take. Raised one jock and one want a be.

TweetHey, have him take a shaker with a few scoops protein powder and just add water when he's there it still has the protein he's needing for practice time. Make sure to get protein he likes or it will be a waste. Nothing worse than being 5 or 6 shakes into a tub and dreading the taste.

TweetWhy not creatine!? It's in the red meats we eat just obviously at a more concentrated dose.. proteins, creatine, and a pre workout N O supp will do him well! The N O will help draw extra blood to the muscle for a better pump and to help heal the muscle. The creatine will help rebuild his muscle quicker for the next workout!

TweetFood...peanut butter, healthy fats, protein, weight gainer shakes, NO TEST BOOSTERS...his test is off the charts already and with proper diet it will get even better!!! Just teach him to eat right...the more he trains, the hungrier he will get...his body will become a bottomless pit for food!!!

TweetI can tell you that when I was 15 I was trying to take everything I could get my hands on to get bigger lol That was wayyyy before creatine supplements were even invented . Most everything back then was Weider. It all was a total rip off but I spent my hard earned money on it trying to get an edge. lol

TweetI wish someone had taken me aside and taught me how to eat at that age. I agree with others that his own body is making plenty of testosterone. Getting the right foods and extra protein should get him a long way.....if he plateaus, maybe mix in creatine.

Tweeti would absolutely not use a test booster. their test is sky high at that age. my kid i got him weight gainer as he just cannot eat enough food to put on mass.
