The male body produces the equivalent of a minor steroid cycle during puberty. If a teen is not producing a higher level, and not as a result of diet or exercise, then that teen may need to see a doctor, not take a supplement.
Also these supplements only take a person to what is called high normal, which practically all healthy teen males already exceed. It will have little if any effect, kind of like watering the lawn during a downpour.
As far as the supplement working or not, it looks like they are attempting to throw everything they could into this thing. It is like ZMA, Old TRIBEX, RED KAT, M, all mixed together, and then a whole bunch of other crap tossed in, you know, just in case. Funny thing is there ain?t enough room for all that shit in only 6 capsules.
