Leuprolide Reference

Plain English

What it is

Leuprolide is an FDA-approved prescription medicine sold under brand names like Lupron Depot and Eligard. It is a GnRH agonist, meaning it is a lab-made copy of a natural hormone that, after a short early rise, lowers the body's sex hormones (testosterone in men, estrogen in women).

What people use it for

Doctors prescribe it for advanced prostate cancer, for endometriosis, and to improve anemia from uterine fibroids before surgery. It is also used to treat children with central precocious puberty, which is puberty that starts too early. It is given and managed by a clinician and is not a body-composition or fitness drug.

What the science shows

It has decades of approved-label evidence in cancer care and hormone conditions, where lowering sex hormones is the goal. Common reported side effects include hot flashes and sweats, headaches, mood changes, and weight change.

The catch

Because it pushes sex hormones very low, it can cause bone loss that may not fully recover, and product labels note a reported risk of heart attack, stroke, and sudden death in men. It is prescription-only and clinician-managed, so off-label or self-administered use is unsafe and outside FDA approval.
