Nandrolone (phenylpropionate / other esters)
Muscle & Strength · Injectable 19-nor steroid
Tier C+
Bottom line
Read Off Label grades Nandrolone (phenylpropionate / other esters) as C+ (5.6/10) based on strong evidence, high benefit magnitude, and a high-risk safety profile.
Preferred over decanoate by more experienced users who want shorter 'bailout window' if sides develop.
Typical use: NPP illicit: 100-200 mg IM every other day — Schedule III US; banned sport.
What this is
Preferred over decanoate by more experienced users who want shorter 'bailout window' if sides develop. Same long detection as parent nandrolone. Classical post-war clinical use as Durabolin.
Mechanism
Same parent as Deca but with shorter esters (NPP = phenylpropionate, ~4-5 day half-life); allows more stable blood levels and faster clearance if side effects emerge
Dose & route
NPP illicit: 100-200 mg IM every other day
