This audio file is intended to increase the production of testosterone in the male body, or at least make the listener feel like it has so that all jocks and aspiring bodybuilders can feel more motivated to push themselves in the gym to build muscle mass and strength, feel more confident, and become more sexual with an increased libido. Though not exactly an erotic file, the feeling of testosterone building in one's testes is sure to get that cock very aroused - while also leaving you pumped up to go work out.
