Applications & Uses

Description

Trestolone, also known as 7α-methyl-19-nortestosterone (MENT), is an experimental androgen/anabolic steroid (AAS) and progestogen medication which has been under development for potential use as a form of hormonal birth control for men and in androgen replacement therapy for low testosterone levels in men but has never been marketed for medical use.

Uses

Trestolone is a synthetic androgen used as a potential hormonal male contraceptive method that induces a state of termporary infertility.
