FAQ Section

What is the exact concentration? 300.0 mg/ml testosterone cypionate – verified by HPLC against USP Testosterone Cypionate USP RS.

Is testosterone cypionate controlled? Yes – DEA Schedule III (U.S.), Class C (U.K.), prohibited by WADA worldwide.

How does it compare to Testosterone Enanthate? Cypionate has slightly longer half-life (~8–12 days vs ~7–10 days) and is the predominant ester in North American clandestine markets.

Does it include IRMS data? Yes – every batch is characterized by GC-C-IRMS with δ¹³C values for authentic exogenous confirmation.

Who may legally acquire Avory Pharma Test Cyp 300? Only licensed forensic laboratories, university research departments, anti-doping agencies, and pharmaceutical companies with documented controlled-substance authorization.

Is it used in official WADA testing? Yes – it is the primary high-concentration testosterone cypionate calibrant and quality-control material in virtually every WADA-accredited laboratory globally.
