What is Nandrolone Decanoate?
Nandrolone Decanoate 300mg/mL (High-concentration DECA — long-acting 19-nor anabolic-androgenic steroid (injectable)) is the decanoate ester of nandrolone — C₂₈H₄₄O₃, MW 428.6. The 300mg/mL formulation provides 50% more dose per mL vs 200mg/mL, reducing injection volume. 19-nor testosterone derivative with high anabolic/low androgenic ratio. Active ~3 weeks per injection. Activates progesterone receptor (PR).
