Primo 100mg/mL – MCT Oil – 10mL Vial

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 delivers 100mg/mL in a 10mL multi dose vial using MCT (medium chain triglyceride) oil as the carrier base; a clean, low viscosity carrier that pairs well with a long acting compound administered on a weekly or twice weekly basis, minimizing injection site discomfort across extended protocol periods.

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 alongside Testosterone Decanoate and Equipoise. This extended active window requires only weekly or twice weekly administration in documented research protocols to maintain stable blood concentration levels. A manageable schedule well suited to the multi dose vial format, where a single 10mL supply covers an extended protocol period without requiring frequent restocking.

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 researched injectable anabolic compounds in the literature. CSD stocks Primobolan across multiple formats including this MCT oil vial, a separate oil based vial variant, and a 10 x 1mL ampoule presentation — the base compound and pharmacokinetic profile remaining consistent across all formats with carrier and packaging representing the primary selection variables.

Every batch of CSD’s Primobolan 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 our injectable range. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
