Clomiphene, 1500mg (25mg/capsule)

Clomiphene is a racemic mixture of two geometric isomers of a triphenylethylene selective oestrogen receptor modulator (SERM): enclomiphene (trans-isomer, predominant ER antagonist) and zuclomiphene (cis-isomer, mixed ER agonist/antagonist). The racemic mixture has a well-characterised clinical pharmacological profile as a SERM used to investigate hypothalamic–pituitary–gonadal axis feedback. Research applications include SERM pharmacology, HPG-axis feedback investigation, and isomeric mixture vs. isolated isomer comparative studies.
