Pregnenolone 0-25mg IR Capsule

Pregnenolone, also referred to as 5-pregnenolone or pregn-5-en-3β-ol-20-one, is a 21-carbon endogenous steroid. It is biosynthesized from cholesterol and is a precursor and a metabolic intermediate to the gonadal steroid hormones and adrenal corticosteroids, including estrogen, progesterone, testosterone, dehydroepiandrosterone (DHEA), cortisol, and cortisone. Pregnenolone is also biosynthesized from cholesterol within the central nervous system and the peripheral nervous system, which lends its classification as a neurosteroid.
