Androstenedione

Quick Detail: Product Name: Androstenedione;Androstene Synonyms: 4-AD;4-Androstene-3,17-dione; 4-androstenedione; Androst-4-ene-3,17-dione; ;androst-4-ene-3,17-dione CAS No.: 63-05-8 M.F.: C19H26O2 M.W.: 286.41 EINECS No.: 200-554-5 Assay: 98.5% Packing: foil bag Appearance: White crystalline powder 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. Androstene has both anabolic and androgenic effects on your body. Anabolic effects refer to "building up" muscle mass, while androgenic refers to masculinizing effects such as increasing body hair and facial hair and promoting muscle growth.

Adrenal glands, ovaries and testicles naturally produce androstenedione. Once released into your bloodstream, androstenedione can convert to both testosterone and estrogen. Benefits: 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.

A highly publicized study indicates that androstenedione may not live up to its hype. The study published in the June 2, 1999 issue of the Journal of the American Medical Association compared 300 mg with a dummy pill in 20 men ages 19 to 29 during an eight-week weightlifting program. Researchers found no difference in strength between the two groups of men.

Applications: Androstene is also called andro or androstenedione, a naturally occurring human steroid. It was once used as a dietary supplement to help athletes increase muscle mass, but the Federal Drug Administration has banned the sale and distribution of this anabolic steroid due to the severely negative side effects associated with its use.

Androstenedione is a hormone produced naturally in the body by the adrenal glands, the ovaries (in women), and the testicles (in men). The body first manufactures DHEA , then turns DHEA into androstenedione, and finally transforms androstenedione into testosterone, the principal male sex hormone. Androstenedione is also transformed into estrogen.

Androstenedione is widely used by athletes who believe that it can build muscle and increase strength. However, there is no evidence that it works. Furthermore, androstenedione supplements may cause positive urine tests for illegal steroid use, due to the common presence of a contaminant (19-norandrostenedione).

The typical recommended dose of androstenedione is 100 mg 2 times daily with food. Packaging & Delivery 1.Sufficient stock, to delivery promptly at the very day when receive the payment 2.Sophisticated and professional logistic agent.
