THE HORMONE CONTROLLER

Triptorelin Acetate, Triptorelin Pamoate, Decapeptyl

Triptorelin is a powerful GnRH analog used medically to control sex hormone levels. It initially stimulates hormone production but with continued use causes the pituitary to downregulate, dramatically reducing testosterone or estrogen. It's FDA-approved for prostate cancer, endometriosis, precocious puberty, and gender-affirming care.
