What is Estradiol Cypionate?

Estradiol Cypionate (Long-acting injectable oestrogen research compound) is the cypionate ester of 17β-oestradiol — C₂₆H₃₆O₃, MW 396.6. Esterification provides extended-release oestrogen activity (peak ~3–5 days, active ~2–3 weeks) vs native oestradiol.

Primary injectable oestrogen reference compound for HRT and oestrogen receptor research.
