The second most common reason is probably to address a fear that libido might be lost without it. It is true that when added to normal androgen levels, Proviron has an androgenic effect that in many cases improves libido. However, most anabolic steroidsalso have this same property. In a steroid cycle, adding Proviron accomplishes nothing further. Or in the case of anabolic steroids such as Deca which for other reasons may adversely affect libido, Proviron provides no greater help against that than do various other anabolic steroids.

One of the interesting things about Proviron is that while it assays (tests) as being an effective anabolic in the rat, it is virtually useless for building muscle in man. This may be due to enhanced conversion in muscle tissue to the diol, but it may instead be due to some unknown reason.

Another interesting thing is that it enjoys some practical use as a pro-sexual agent inbetween cycles. Typically 50 mg is taken shortly before improved performance is expected to be useful.

Contrary to common belief, Proviron is somewhat inhibitory of the HPTA. Using it during the recovery phase as part of post-cycle therapy is counterproductive. It is also inadvisable for this reason to use it continuously while intending to be off-cycle, but occasional recreational use presents no problem.

Proviron has been used in female bodybuilding, but it has almost undoubtedly the worst ratio of anabolic effect to virilizing effect of any anabolic steroid in common use. The perceived value is in fat loss and 'hardening,' but friendlier choices exist for this. Most of that value is from anti-estrogenic effect, which Nolvadex can also accomplish. And for an androgen component, there are better choices, including, including Primobolan.

Unlike almost all other orals, Proviron is not hepatotoxic, as it is not 17-alkylated.

Tablets are typically 25 mg, and taken one or two at a time. Amounts greater than this have no further effect on improving libido off-cycle, but if used for a specific occasion, whether on-cycle or off-cycle, may temporarily improve vascularity, if it is already noticeable but has room for improvement.

Proviron is the chemical name of active ingredient in Proviron. Proviron was a registered trademark of Schering AG in the United States and/or other countries prior to cancellation.
