It sounds like you are under 18 if you are asking and assuming you mean something like test booster supplements correct? If you are that young you don't need them bro, your body, if its not already, should be pumping out massive amounts of natural test, taking that stuff so young can screw up your normal production of test. I would wait until you are at least 20.
Get some good protein, branch chain amino acids (BCAA), and glutamine supplement and thats all you should need
