Androstenedione
Background Information

- Naturally found in some plants
- Gained popularity in 1998 when Mark McGuire used it during his MLB season, however, it has been around since the 1930s
Function
- It is considered a natural alternative to steroids because as a prohormone to testosterone, super supplementation may increase testosterone level
Desired Effects on the Body
- Possible increases in testosterone, muscle strength and muscle mass when high doses are taken
Research Evidence
- Increases in testosterone are not found at moderate doses
Potential Side Effects
- If abnormal levels of testosterone are obtained a side-effect profile would be similar to anabolic steroids. However, because in research only small increases in testosterone are seen, these are thought to be rare.
