Synthesis method

3?-Hydroxy-5-Androsten -17- Ketone, also known as dehydroepiandrosterone, abbreviationDHAor DHEA. It has a weak androgenic effect and can be detected in urine, often excreted in the form of sulfate ester.

Purpose

DHEA?dehydrpepiandrosterone) is the precursor of androstenedione, testosterone and other male hormones, and can increase the levels of male hormones. DHEAIt is the most abundant hormone in the human body, thousands of times more than other hormones in the body. It is produced by the adrenal glands and is also known as“Anti-aging hormone” . Research shows:DHEACan regulate and promote other substances in the body18The secretion of steroid hormones in the body has the functions of promoting metabolism, maintaining normal functions of the human body, anti-aging and enhancing immunity, so it is also called“Youth Factor“. Clinical research,DHEACan improve immune function, resist degeneration and prevent infectious diseases, and can promote the immune systemtCell,bProduction of cells and macrophages, preventing bacterial and viral infections, inhibiting obesity and preventing cancer , lower cholesterol and blood lipids
