Androstenedione is said to enhanceathletic performance and strength by increasing testosterone production, thereby building muscle.

It did, however, increase estrogen levels, an effect that would not be considered favorable. Curiously, some evidence suggests that androstenedione does raise testosterone levels levels in women; again, this is not likely to produce favorable results, and it could cause harm (seeSafety Issues).
