Mesterolone (Proviron)
by Bill Roberts - Proviron, an anabolic steroid, is particularly interesting. I suspect that it not only acts as an antiaromatase but in an unknown DHT-like anti-estrogenic manner. This might involve estrogen receptor downregulation for example. In any case, aromatase inhibition and/or Clomid don’t seem to give the same effect on appearance and muscle hardness as when Proviron is included.
This drug has good binding to the androgen receptor, but in muscle tissue most of it never reaches the androgen receptor because it is enzymatically converted to the diol. Thus, it is not an effective anabolic. It is somewhat effective as an anti-gyno agent, however, and appears to reduce estrogenic bloating if that problem exists.
Proviron reduces either levels of estrogen or the effect of estrogen. Thus, it is useful for avoiding gynecomastia, although it probably should not be relied upon as the sole drug for that. It is not hepatotoxic. It has the usual side effects of anabolic/androgenic steroids, with the added effect that it is particularly prone to cause erections.
