M100-Primo 100 mg/mL (10 mL) – Research Use Only
M100-Primo (Methenolone Enanthate-100) is a sterile, oil-based research solution containing Methenolone Enanthate at a concentration of 100 mg/mL, supplied in a 10 mL multi-dose vial.
Methenolone Enanthate is an esterified derivative of methenolone designed for extended-release characteristics in research environments. The enanthate ester allows investigators to evaluate prolonged pharmacokinetic behavior, sustained androgen receptor interaction, and extended-duration pharmacodynamic response models.
This product is supplied as a clear, pale yellow oil solution and is strictly intended for research and laboratory use.

Research Summary
M100-Primo provides researchers with methenolone in an enanthate-esterified form, allowing evaluation of prolonged-release characteristics and sustained receptor activity models.
Compared to acetate-based formulations, which offer shorter release intervals, Methenolone Enanthate supports extended-duration laboratory studies and controlled pharmacodynamic observation over longer timeframes.
