i cant see gh being low in a kid 14, unless its a chemical balance in the body and therefor doctors recommendation. gh doesnt start to drop until your 20's for the average person. if it is just a store bought supp it wont do shit, plus its probably a crap supplement. sytropin and hgh energizer and all that stuff is shit. maybe if you took 3 times the recommended dosage there would be enough l-arginine and other ingredients to do something for recovery needs. the only hgh thats worthwhile is the shit you inject. keep him away from fast food, sodas, junk food, and as much pre packaged shit as possible, otherwise let him eat everything in the house and get him into sports or a gym. but most kids will prefer sports
