17β-Hydroxy-2-(hydroxymethylene)-17-methyl-5α-androstan-3-one

Description:

17β-Hydroxy-2-(hydroxymethylene)-17-methyl-5α-androstan-3-one, commonly known as Mesterolone, is an anabolic steroid with a chemical structure that includes a steroid nucleus characterized by four fused carbon rings. It features a hydroxyl group at the 17β position and a hydroxymethylene group at the 2 position, contributing to its unique properties. Mesterolone is known for its androgenic effects and is often used in clinical settings to treat conditions related to testosterone deficiency. It has a relatively low anabolic activity compared to other anabolic steroids, making it less effective for muscle building but useful for enhancing male fertility and libido. The substance is typically administered orally and is recognized for its ability to improve protein synthesis and nitrogen retention in the body. Mesterolone is also noted for its potential to inhibit the aromatization of testosterone to estrogen, which can be beneficial in managing estrogen-related side effects. However, like other anabolic steroids, it may have side effects and is subject to regulations in sports and medicine.
