Testosterone Enanthate is a long acting single ester testosterone compound with a well documented half life of approximately 7–10 days, providing stable and predictable blood concentration levels suited to research protocols requiring infrequent administration. This formulation is manufactured by F40 Biotech and delivers 250mg/mL in a 10mL multi dose vial using MCT (medium chain triglyceride) oil as the carrier base; chosen for its exceptionally low viscosity, clean composition, and well documented tolerability profile that makes it one of the most comfortable carriers available for injectable testosterone formulations.
MCT oil’s ultra low viscosity is a particularly relevant advantage at 250mg/mL, where heavier traditional carriers like cottonseed and sesame oil can present increased draw and administration resistance. The result is a high concentration testosterone formulation that handles smoothly and consistently. A practical consideration for researchers conducting repeated administrations over extended protocol periods. F40 Biotech’s formulation delivers these handling characteristics alongside the same pharmacokinetic profile as all Testosterone Enanthate 250mg/mL MCT oil preparations, 7–10 day half life, weekly or twice weekly administration schedule, and stable sustained blood concentration levels throughout.
F40 Biotech formulations are stocked by Canada Steroid Depot following the same rigorous third party lab verification process applied to every product in our range. Each batch is tested for concentration accuracy and purity before being made available, with COA documentation available on request. CSD’s sourcing standards apply uniformly across all manufacturers we carry, and F40 Biotech’s Testosterone Enanthate meets those standards consistently. Researchers comparing manufacturer options within CSD’s Testosterone Enanthate MCT oil range will find the base compound, concentration, and carrier identical across listings. Manufacturer selection coming down to availability, batch preference, and individual sourcing history.
All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior. Canada Steroid Depot has supplied Canadian customers with consistently verified, accurately dosed compounds for years across all manufacturers in our range.

This Testosterone Enanthate is manufactured by F-40 Biotech, a verified domestic Canadian supplier producing injectable anabolic compounds to CSD's quality standards. All F-40 Biotech products stocked by CSD are independently HPLC tested by accredited third party laboratories before listing, confirming concentration accuracy at 250mg/mL and compound identity as Testosterone Enanthate. A certificate of analysis is available on request for this specific lot number.
This F-40 Biotech formulation combines verified domestic Canadian manufacturing with MCT oil, one of the lightest and lowest viscosity carrier oils available for injectable formulations. MCT oil flows freely through fine gauge needles at room temperature without pre warming, produces minimal injection site discomfort compared to heavier carriers such as cottonseed or sesame oil, and absorbs rapidly at the injection site depot. For researchers prioritizing both manufacturer traceability and injection comfort, this F-40 Biotech MCT formulation represents the optimal combination of both factors in CSD's Testosterone Enanthate range.
Testosterone Enanthate is a long acting esterified testosterone with a half-life of approximately 7–10 days; the most widely researched testosterone ester for TRT, hypogonadism, anabolic steroid, and hormonal replacement protocols. It provides stable serum testosterone concentrations with once or twice weekly administration, making it the most practical single ester testosterone for both short and long term research protocols.
Once weekly administration is the most common research schedule; a single injection of 0.5–1mL delivers 125–250mg weekly. Twice weekly administration splitting the weekly dose into two equal injections produces tighter serum testosterone stability with smaller peak to trough fluctuations, the preferred approach in TRT research where hormonal consistency is the primary objective. This 10mL F-40 Biotech vial provides sufficient compound for 10 weekly doses or 20 twice weekly doses.
Yes! This F-40 Biotech batch has been independently HPLC tested by an accredited third party laboratory confirming concentration accuracy at 250mg/mL and compound identity as Testosterone Enanthate. A certificate of analysis is available.
