Effective Androstenedione Sex Steroid Hormone Pharma Raw Materials CAS 63-05-8
Androstenedione is a naturally occurring steroid that has both androgenic and anabolic qualities. It is produced by the adrenal glands, ovaries and testicles. The body converts this to both testosterone and estrogen. The potency of any given steroid is valued by its ability to help build up muscles, which is referred to as anabolic quality. Androgenic effects, which bring about masculine features is quantified as well. Androstenedione became popular when results showed the use enhanced the abilities and muscular mass of professional athletes around the world. It did not take long to show up in the world of bodybuilding and weightlifting.

Androstenedione is naturally found in meat, some plants, and in the human body. In the 1970s, androstenedione was developed by East German researchers in order to increase performance in their athletes. Androstenedione, commonly known as andro, was not introduced into the United States markets until the mid-1990s. The goal of the andro is to increase testosterone levels so athletes can train harder and recover in less time. The claim is that harder training would ultimately lead to a gain in muscle mass and power. Although this goal has not been proven that andro promotes muscle growth, studies have shown andro increases androstenedione, testosterone, and estrogen levels.
1. Performance Enhancement:
The combination of anabolic steroids, when administered to cause levels higher than normally found in the body, and strength training results in an increase in muscle size, strength, and fat free mass. Further effects are increased red blood cell mass, improved mood/aggression, and blunting of the catabolic effect of heavy training. These latter effects may enable endurance athletes to train harder while minimizing overtraining. Whether androstenedione use yields these performance enhancing effects, though, is yet to be directly determined.
2. boost libido in men and women:
Some body builders report anecdotally that they notice increased strength on the days they work out when they use it. Others use it occasionally to boost sex drive or wellbeing. Those who are young and already have high levels of testosterone or androstenedione in their system are not likely to notice much of a sex boosting effect. Middle aged and older individuals may notice the benefits more easily. It is potentially an alternative to DHEA or testosterone as a form of androgen replacement in aging men or women.
How does it work?
In the body, it is produced by the adrenal glands and gonads from dehyroepiandrosterone (DHEA or 17- alpha-hydroxyprogesterone). DHEA is converted into androstenedione an the enzyme in the gonads. Androstenedione is a precursor of testosterone. Once the androstenedione is taken orally, it makes it into the liver where it is almost destroyed completely, the amount that survives combine with the enzyme 17 beta-hydroxysteroid dehydrogenase to make testosterone as shown in the figure below. Taking androstenedione orally can increase androstenedione blood serum levels over 300 percent after about 2 hours and remaining high for 4 hours. Studies have shown that androstenedione by itself does not produce increased muscle mass but once converted into testosterone in the liver, the elevated testosterone levels may lead to muscle mass gain, but not proven.
Side effects specific to men can include testicular atrophy or the shrinking of the testicles, reduced sperm count, infertility, baldness, and the development of breasts. For women, side effects can include enlargement of the clitoris, changes in the body contour growth of facial hair, disruption of the menstrual cycle, deepened voice and infertility.
How to Take Androstenedione?
The exact dosages for Androstenedione have not been determined because of the unknowns of this supplement, but during research, men were given 50-100mg a day and had a significant increase in testosterone levels. Some were up 237%! For strength athletes, it has been shown that when taken one hour before training, you may experience added strength due to the immediate rise in testosterone levels.
Some other supplements may be added to your Androstenedione cycle to increase the benefits such as DHEA, Tribulus, and Chrysin. Zinc is also am important supplement to add because it is a mineral necessary for the natural production of testosterone, which may boost the effects.
