What is Testosterone Cypionate 50mg/mL?

Testosterone Cypionate 50mg/mL (Low-dose long-acting esterified testosterone (injectable)) is the cypionate ester of testosterone — C₂₇H₄₀O₃, MW 412.6. The 50mg/mL low-concentration format provides precise, lower-dose testosterone delivery for physiological replacement range research protocols. Peak ~1–3 days, active ~2 weeks. Free testosterone activates the androgen receptor (AR). Aromatases to oestradiol via CYP19A1.

Research Applications
