Methyltestosterone (MT)

Methyltestosterone is one of the oldest available oral steroids. It is produced by many various manufacturers and sold in a number of countries including the U.S.. It is quite androgenic, with minimal anabolic effects. For athletic purposes, methyltestosterone is generally only used to stimulate aggression among power lifters and those looking to boost up their workouts. Testosterone and the synthetic androgen, 17 alpha-methyltestosterone (MT), have been shown to increase uterine weights and alter uterine morphology. However, whereas the mechanism of action of testosterone in the uterus has been studied, it is not known if the actions of MT are mediated through androgen (AR) or estrogen (ER) receptors. MT, at 0.5 or 10 mg/kg per day, increases uterine weight and alters uterine morphology in a dose-dependent manner.
