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 delivers 250mg/mL in a 10mL multi dose vial using sesame oil as the carrier base; a traditional and widely used injectable medium with a long history in pharmaceutical testosterone preparations dating back to some of the earliest clinical formulations.
Sesame oil carries some meaningful differences worth noting compared to MCT oil based formulations. It has a slightly higher viscosity at room temperature but is exceptionally well tolerated, with a long track record in injectable pharmaceuticals. Some researchers prefer sesame oil based testosterone for its historical precedent in clinical literature and its compatibility with sensitive formulation requirements. Warming the vial slightly before administration is a common practice to improve flow with sesame oil carriers.
At 250mg/mL this formulation offers a higher concentration than CSD’s 200mg/mL MCT oil Test E variant, allowing for lower injection volumes per dose while maintaining equivalent compound delivery; a practical consideration in research protocols where minimizing injection volume is a priority.
Every batch of CSD’s Testosterone Enanthate is third party lab tested for concentration accuracy and purity prior to release, with COA documentation available on request. Canada Steroid Depot has been supplying Canadian customers with consistently verified, accurately dosed injectables for years, and our Testosterone Enanthate range remains among our most reordered product lines. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
Store at room temperature away from direct light and heat. Do not freeze. Intended for research purposes only.
The active compound Testosterone Enanthate at 250mg/mL is identical to other Test E formulations in our catalogue. The difference is the carrier oil. Sesame oil is one of the most historically used pharmaceutical carrier oils for injectable testosterone. It is the carrier used in many original pharmaceutical testosterone preparations and has decades of documented biocompatibility and tolerability data. Some researchers specifically prefer sesame oil based formulations due to familiarity and its established pharmaceutical heritage, while others prefer lighter modern carriers such as MCT or grape seed oil. All carrier oils in CSD's injectable range are pharmaceutical grade.
Yes! Sesame oil has one of the longest documented histories of use as a pharmaceutical carrier oil for injectable formulations, with decades of safety data from its use in original pharmaceutical testosterone preparations. It is well tolerated by the majority of research subjects. The primary consideration is sesame allergy; researchers with known sesame sensitivity should select an alternative carrier such as MCT, grape seed, or cottonseed oil formulations from our catalogue.
Sesame oil is a medium viscosity carrier oil; slightly more viscous than MCT or grape seed oil at room temperature, but significantly less viscous than cottonseed oil. It flows well through standard 23–25 gauge injection needles at room temperature in most conditions. In cold environments, briefly warming the vial between the palms for 30–60 seconds before drawing will improve flow. Post injection site reactions are comparable to grape seed oil and generally mild.
Administration frequency is determined by the ester half-life; 7–10 days for Testosterone Enanthate not the carrier oil. Once weekly administration is the most common research schedule, providing stable supraphysiological testosterone levels throughout the protocol. Twice weekly administration splitting the dose into two equal injections produces tighter serum level stability and is preferred in TRT research contexts where hormonal consistency is the primary objective.
Yes! This 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.
