What this means
- 01
FDA has approved Goserelin for at least one labeled indication, so a pharmaceutical-grade product exists in the United States and is dispensed on prescription.
- 02
Approval is indication-specific. Uses outside the label are a clinical decision for a prescriber, not something the approval itself authorizes.
- 03
Unlicensed online vials, including those labeled "research use only", are not the approved product and are not covered by the approval.
What Goserelin is
An FDA-approved GnRH agonist implant that suppresses sex hormones for prostate and breast cancer and endometriosis.
Goserelin is a GnRH agonist delivered as a slow-release implant, approved as Zoladex. Like leuprolide it suppresses sex hormone production after an initial flare and is used for prostate cancer, hormone-sensitive breast cancer, and endometriosis.
Mechanism: Continuous GnRH receptor activation desensitizes the pituitary, reducing LH, FSH, testosterone, and estrogen.
Regulatory history: FDA-approved (Zoladex)
How FDA treats this kind of product
Approves prescription drugs by indication and polices unapproved products, including peptides sold online. Compounding pharmacies may prepare some compounds under a prescription when the FDA places them on a permitted bulk-substances category.
The classification above is the The Longevity Archive reading of U.S. Food and Drug Administration listings for Goserelin at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
