Methenolone Enanthate, widely known by its pharmaceutical brand name Primobolan, is a long acting anabolic compound derived from dihydrotestosterone (DHT) with a distinctly mild androgenic profile relative to most injectable anabolic compounds. CSD’s formulation supplies 100mg/mL across a 10 x 1mL single use ampoule format. Individually sealed, pre measured glass ampoules delivering single use sterility and consistent per dose measurement across the extended administration timelines typical of long acting ester protocols.

The enanthate ester gives Primobolan a half life of approximately 10–14 days, placing it among the longer acting injectable anabolic compounds in CSD’s range. The ampoule format is particularly well suited to this extended active window. Researchers working through a 10 ampoule supply over multiple weeks benefit from hermetic seal integrity on every individual dose, eliminating the repeated puncture and cumulative handling variables associated with multi dose vials across long duration protocols.

Primobolan’s defining research characteristic is its complete inability to aromatize as a DHT derived compound it produces no estrogenic conversion regardless of dose. This non aromatizing profile, combined with its well documented mild androgenic activity and long pharmaceutical history spanning clinical approval for muscle wasting and malnutrition treatment, makes it one of the more extensively studied injectable anabolic compounds in the literature. CSD stocks Primobolan in both ampoule and 10mL vial formats, giving researchers flexibility in packaging format selection without switching compounds or manufacturers.

Every batch of CSD’s Primobolan ampoules is third party lab tested for concentration accuracy and purity prior to release, with COA documentation available on request. Canada Steroid Depot has supplied Canadian customers with consistently verified, accurately dosed compounds for years, and Primobolan remains one of the more sought after products across both our vial and ampoule ranges. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
