What is NPP 200mg/mL (Nandrolone Phenylpropionate)?
Nandrolone Phenylpropionate 200mg/mL (High-concentration short-acting 19-nor AAS (injectable)) is the phenylpropionate ester of nandrolone — C₂₇H₃₄O₃, MW 406.6. The 200mg/mL formulation doubles the dose per mL vs 100mg/mL, reducing injection volume for equivalent dose protocols. Short-acting ester (peak ~1–2 days, active ~5–7 days). High anabolic/low androgenic ratio. Activates progesterone receptor. Partial aromatisation (~20% of testosterone rate).
