Product description:
Androstenedione is the common precursor of male and female sex hormones.Some androstenedione is also secreted into the plasma, and may be converted in peripheral tissues to testosterone and estrogens.
Androstenedione is said to enhance athletic performance and strength by increasing testosterone production, thereby building muscle. However, in double-blind studies, when androstenedione was given to men, it did not alter total testosterone levels, nor improve sports performance, strength, or lean body mass. 2-7 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 (see Safety Issues ). 8,11 The most consistent effect of androstenedione is to increase estrogen levels.
