What is Methenolone Enanthate?
Primobolan Depot (Methenolone Enanthate — long-acting injectable anabolic-androgenic steroid) is the enanthate ester of methenolone — C₂₇H₄₂O₃, MW 414.6. The injectable form of Primobolan provides longer active duration (peak ~3–5 days, active ~10–14 days) vs the oral acetate form. Notably mild androgenic profile with high anabolic-to-androgenic ratio. Does not aromatise to oestrogen. Low progestogenic activity.
Research Applications
Mild-Anabolic Injectable Research

Non-Aromatising Injectable AAS
Anabolic research without oestrogen confounds — injectable alternative to oral Primobolan
Androgen Receptor Binding Studies
Moderate AR affinity — characterised anabolic-to-androgenic binding ratio research
Lean Mass Preservation
Muscle preservation in catabolic models without androgenic or oestrogen co-effects
