Pregnenolone – Powder, 5 grams

Pregnenolone is a pregnane-class steroid derived enzymatically from cholesterol via the cholesterol side-chain cleavage enzyme (CYP11A1), positioned as the common biosynthetic precursor for the entire downstream steroidogenic cascade. Research interest centers on its role both as a steroidogenesis intermediate and as a neurosteroid with independent signalling activity in the central nervous system. Research applications include steroidogenic pathway studies, neurosteroid receptor pharmacology, and CYP11A1 enzyme kinetics research.
