What this means
- 01
MHRA has approved Gonadorelin for at least one labeled indication, so a pharmaceutical-grade product exists in the United Kingdom 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 Gonadorelin is
Synthetic gonadotropin-releasing hormone, historically approved for diagnosis and fertility and now used to preserve testicular function during testosterone therapy.
Gonadorelin is the synthetic form of gonadotropin-releasing hormone (GnRH), the hypothalamic signal that drives pituitary LH and FSH release. It was previously FDA-approved for diagnostic and fertility uses.
Mechanism: Stimulates pituitary release of LH and FSH when given in pulses, mimicking natural GnRH signaling; continuous exposure instead desensitizes and suppresses it.
Regulatory history: Previously FDA-approved (diagnostic/fertility); used off-label and compounded in TRT
How MHRA treats this kind of product
Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency listings for Gonadorelin 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.
