Overview Information

1-Androsterone is a type of chemical known as a "prohormone." These chemicals are changed by the body to other "muscle-building" hormones such as testosterone. Very little is known about the safety of 1-androsterone. There is concern it might cause serious side effects similar to those caused by other "muscle-building" hormones.

1-Androsterone is included as an ingredient in a variety of supplements marketed to athletes and bodybuilders.

How does it work?

After 1-androsterone is taken, the body changes it into other chemicals called hormones. Some of these hormones are very similar to testosterone. Testosterone can help build muscle, but can also cause dangerous side effects.

Uses & Effectiveness?

Insufficient Evidence for

  • Athletic performance. Early research shows that taking 1-androsterone 330 mg daily might help increase strength in people who lift weights. It might also help lower body fat.
  • Other conditions.
More evidence is needed to rate 1-androsterone for this use.
