Sample Use Guides

In Vivo Use Guide

The tablets should be swallowed whole with some liquid. The recommended doses are: 1 tablet (25 mg) 3 times/day (reduced efficiency and potency disturbances), 1 tablet 2-3 times/day (Infertility), 1-2 tablets 3 times/day (for development of secondary male sex characteristics in hypogonadism).

Route of Administration: Oral

In Vitro Use Guide

Mesterolone showed activation effect on mutant androgen receptor (expressed in HeLa and COS-7 cells) at doses 0.1–300 nM.
