Raw Steroid High Purity Powder 4-Androstenedione / 4-AD CAS 63-05-8 For Bodybuilding

Abstract

4-Androstenedione is the common precursor of male and female sex hormones. Some 4-Androstenedione is also secreted into the plasma, and may be converted in peripheral tissues to testosterone and estrogens.

4-Androstane-diones are a pair of isomeric steroids which differ at the 5-position. They are distinguished as 5α-androstane-dione and 5β-androstane-dione. In humans, 5α-androstane-dione is a metabolic precursor of both testos-terone and estrone.

 

Simplified hormone drugs, from the testis or urine extracted with the role of a male hormone steroids, norethisterone, testosterone propionate in the middle Body, is widely used in small rheumatoid arthritis, diuretic, and a variety of contraceptive to control infectious inflammation.

4-Androstenedione can be synthesized in one of two ways.

The primary pathway involves conversion of 17-hydroxypregnenolone to dehydroepiandrosterone by way of 17,20-lyase, with subsequent conversion of dehydroepiandrosterone to 4-Androstenedione via the enzyme 3-β-hydroxysteroid dehydrogenase. The secondary pathway involves conversion of 17-hydroxyprogesterone, most often a precursor to cortisol, to 4-androstenedione directly by way of 17,20-lyase. Thus, 17,20-lyase is required for the synthesis of 4-androstenedione, whether immediately or one step removed.

The production of adrenal 4-Androstenedione is governed by ACTH, whereas production of gonadal 4-Androstenedione is under control by gonadotropins. In premenopausal women, the adrenal glands and ovaries each produce about half of the total 4-androstenedione(about 3 mg/day). After menopause, 4-androstenedione production is about halved, due primarily to the reduction of the steroid secreted by the ovary. Nevertheless, 4-androstenedione is the principal steroid produced by the postmenopausal ovary.
