i hate to say this bro... but if he's in HS... do not give him anything.. that's one of the main reasons we have a problem with this hobby in the government... too many young ones taking shit and getting hurt... that's why ephedra is gone to begin with.. a 300lb high school football player doing triple sessions, taking 3 times the recommended doses, in full gear, and above all .. doing it all in texas!... hot hot hot.. wrestling environment in itself is a hot/steamy workout.. if i were you, i would not do it.
In regards to making weight.. make a strict diet for him - either lean him out or cut his calories - change his training routine - do it all at the same time and keep on his ass to stay focused and he'll drop his weight. that's the right way to do it. don't let special supps be the magic pill/shortcut to get the job done and make it easier..
that's a big problem that people have with our hobbie.. and that's they think we are cheating, when in reality it's to go beyond our natural potential and achieve higher goals.. mediocre goals and shortcuts are not the reason to take this stuff anyway..
maybe that's just my .02, and I took all sorts of supps when i was younger when they first came out - DHEA, Vanadyl Sulfate, Chromium Picolinate, Creatine, Protien, ECA stacks (either stacker style or truck driver brand (ephedra/nodoz/aspirine) but never pharm's/AAS till i was ready and willing to be educated/learn etc..
not trying to piss on anyone's parade but ..
