Estradiol Cypionate (E2C) is the most potent endogenous oestrogen (17β-estradiol) esterified with cypionate for extended release (~14-day half-life). Estradiol binds ERα and ERβ with high affinity to drive genomic transcription of oestrogen-responsive genes. ERα mediates classic reproductive, cardiovascular, and bone effects; ERβ modulates CNS, immune, and anti-proliferative activity. Long-acting injectable form enables sustained, stable oestrogen levels for HRT research, transgender healthcare models, and comparative ER pharmacology — contrasting the short half-life of unconjugated oestradiol.

Comparative HRT
Long-acting oestrogen depot for HRT pharmacokinetic modelling
Estradiol Cypionate is 17β-estradiol esterified with cypionate for ~14-day injectable half-life. It is the most potent endogenous oestrogen, binding ERα and ERβ to regulate reproductive, cardiovascular, bone, CNS, and immune functions. Used in research for ER pharmacology, HPG axis oestrogen effects, bone density, and long-acting HRT pharmacokinetic modelling.
