Proviron is used in school medicine to ease or cure disturbances eaused by a deficiency of male sex hormones. Many athletes, for this reason, often use Proviron at the end of a steroid treatment in order to increase the reduced testosterone production. This, however is not a good idea since Proviron has no effect on the body’s own testosterone production but-as mentioned in the beginning-only reduces or completely eliminates the dysfunctions caused by the testosterone deficiency. These are in particular impotence which is mostly caused by an androgen deficiency that can occur after the discontinuance of steroids, and infertility which manifests itself in a reduced sperm count and a reduced sperm quality. Proviron is therefore taken during a steroid administration or after discontinuing the use of the steroids, to eliminate a possible impotency or a reduced sexual interest. This, however does not contribute to the maintainance of strength and muscle mass after the treatment. There are other better suited compounds for this (see HCG and Clomid). For this reason Proviron is unfortunately cunsidered by many to be a useless and unnecessary compound.
