Androstenetrione

OTHER NAME(S): 6-OXO, ADT, Androst-4-ène-3,6,17-trione, 4-androstene-3,6,17-trione, androst-4-ene-3,6,17-trione, Androstenetriona, Androsténétrione

Overview

Androstenetrione is a steroid. Despite serious safety concerns, it is used for improving athletic performance.

Androstenetrione is promoted as an alternative to “prohormones” such as androstenedione. Marketers claim that androstenetrione increases the body's natural testosterone levels and therefore is free from the negative side effects of prohormones. There is no reliable evidence to back these claims.

The body converts some of the male hormone testosterone to the female hormone estrogen. Androstenetrione blocks this conversion. Some people suggest that the body makes up for the falling estrogen level by making more testosterone. They further suggest that the higher levels of testosterone will improve athletic performance. Some people who sell androstenetrione say that it increases total testosterone by 188% and free testosterone by 226% over 3 weeks of use. But there is no scientifically reliable research in people that supports these claims.
