Mestanolone Description

Proviron (mesterolone) is an interesting anabolic steroid, though it is not of much value to bodybuilding. It seems that the most common reason for many to consider including it in a steroid stack is for anti-estrogenic activity. In the days before anti-aromatases and the use of SERMs (selective estrogen receptor modulators) such as Clomid and Nolvadex, there was some merit to this.

An amount of aromatizing steroid marginally over the amount that would be tolerable without Proviron became tolerable with the inclusion of it. However, the effect is indeed only marginal, and much better anti-estrogenic agents now exist. When these are used, there is no need for Proviron as an anti-estrogen.


  1. Mestanolone, as a male hormone and anabolic hormones, is used for bodybuilding muscle supplements. Mestanolone is very useful during cutting phases or when one wishes to avoid excess weight gain.
  2. Mestanolone is used for male hypogonadism and decreased sperm infertility.

Dose of Mestanolone

The recommended dosage for mestanolone users is 10-20 mg/day for 6-8 weeks, which is often enough to keep blood serum levels well above baseline with this particular drug. M

ore specifically, mestanolone strength and muscle gains are largely on par with those of the DHT-derived anabolic steroid Winstrol (Stanozolol). Its anabolic and androgenic effects are typically dose dependent and extremely supportive of testosterone-based cycles. Experienced steroid users have been known to run more aggressive dosages of 30 mg/day of methyldihydrotestosterone.
