Testosterone gel is used as a hormone therapy.If you already have a descent level, then why increase it?You can have side effects from using it, if your level is already normal or high!Side effects include an enlarged prostrate gland, which can swell up(due to the excess DHT produced) and make you impotent, or worse you could develop prostrate cancer!The DHT effects not only the prostrate, but it also attacks the hair follicles in the scalp. thus leaving you with thinning hair, and then finally baldness.You need it when you are developing and going through puberty, but once that is over, it works against you, sort of like a cut off point!Hope that helps!!
