Enclomiphene citrate represents a refined advancement in men’s hormonal therapy. As the active trans-isomer of clomiphene, enclomiphene provides a more targeted and predictable approach to improving testosterone levels in men with secondary hypogonadism.
Unlike clomiphene — which acts as both an agonist and antagonist on estrogen receptors — enclomiphene functions purely as an estrogen receptor antagonist, allowing for a cleaner stimulation of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) production. This results in a natural increase in testosterone without significantly elevating estrogen or compromising fertility [1] [2].
Note: Enclomiphene is not effective in primary hypogonadism where LH levels are already elevated.
At Strive Pharmacy, enclomiphene is available in flex-dose tablets designed for precision, convenience, and optimal patient outcomes.
