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. Activates oestrogen receptors ERα and ERβ — regulates reproductive biology, bone density, cardiovascular function, CNS activity, and metabolic processes. Primary injectable oestrogen reference compound for HRT and oestrogen receptor research.

Research Applications

Oestrogen Receptor Research

ERα and ERβ activation, nuclear signalling, and oestrogen-responsive gene expression

HRT Research Models

Long-acting oestrogen replacement — ovariectomised animal model oestrogen restoration

Bone Density Research

ERα-mediated osteoblast activity and bone mineral density maintenance models

Cardiovascular & Metabolic Research

Oestrogen’s protective cardiovascular effects and lipid profile modulation

CNS Oestrogen Signalling

ERα/β-mediated neuroprotection, neuroplasticity, and mood regulation research
