Pharmaceutical Name : Clomiphene Citrate
Proprietary Name    : Clomiphenez 10TM
Dosage form        : 10mg/Tablet
Clomiphene citrate is the anti-estrogen of choice for improving recovery of natural testosterone production after a cycle, improving testosterone production of endurance athletes, and is also effective in reducing risk of gynecomastia during a cycle employing aromatizable steroids. Clomiphenez is a mixed estrogen agonist/antagonist (activator/blocker) which, when bound to the estrogen receptor, puts it in a somewhat different conformation (shape) than does estradiol. The estrogen receptor requires binding of an estrogen or drug at its binding site and also the binding of any of several cofactors at different sites. Without the binding of the cofactor, the estrogen receptor is inactive. Different tissues use different cofactors. Some of these cofactors are able to bind to the estrogen receptor/Clomiphenez complex, but others are blocked due to the change in shape. The result is that in some tissues Clomiphenez acts as an antagonist -- the cofactor used in that tissue cannot bind and so the receptor remains inactive -- and in others Clomiphenez acts as an agonist (activator), because the cofactors used in that tissue are able to bind.
