Testosterone Enanthate 250mg/mL – Cotton Seed Oil – 10mL Vial

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 cottonseed oil as the carrier base; one of the most historically established carriers in injectable testosterone preparations, with a long track record in pharmaceutical manufacturing dating back decades.

Cottonseed oil has a slightly higher viscosity than MCT oil but is exceptionally well tolerated with a proven compatibility profile in long term injectable use. It remains the carrier of choice in many traditional pharmaceutical testosterone preparations precisely because of its stability and shelf life characteristics. Researchers selecting between CSD’s cottonseed oil and sesame oil Test E variants will find the base compound and concentration identical;  the carrier choice comes down to personal tolerance history and formulation preference.

At 250mg/mL this formulation delivers a higher concentration than CSD’s 200mg/mL MCT oil Testosterone Enanthate variant, allowing for reduced injection volumes per dose while maintaining equivalent compound delivery. For research protocols where minimizing administration volume is a consideration, higher concentration single ester formulations like this one offer a practical advantage without altering the pharmacokinetic profile of the compound itself.

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.
