Testosterone No Ester 100 mg/mL (TNE-100) – Research Use Only
Testosterone No Ester-100 is a sterile, oil-based research solution containing Testosterone (base) at a concentration of 100 mg/mL. Unlike esterified forms of testosterone, Testosterone No Ester (TNE) does not contain an attached ester chain, allowing researchers to study the properties of unmodified testosterone in non-clinical laboratory settings.
Due to the absence of an ester, Testosterone No Ester demonstrates rapid bioavailability in research models, making it particularly useful for studying immediate androgen receptor interactions, acute hormonal response, and short-duration pharmacodynamic effects.
This product is supplied as a clear, colorless to pale yellow oil solution in a sealed multi-dose vial and is strictly intended for laboratory and research purposes.

Research Summary
Testosterone No Ester-100 provides researchers with access to non-esterified testosterone, allowing direct evaluation of testosterone’s biological activity without the influence of ester chain modification. Because it lacks an ester group, it is particularly useful in short-duration and rapid-onset pharmacodynamic studies.
In contrast, Testosterone Enanthate-250 contains a long-chain ester that slows release and prolongs activity. Comparative studies between these two compounds help researchers understand how esterification alters pharmacokinetics, bioavailability, and hormonal response.
