Catalog Description

Gonadorelin is a synthetic decapeptide identical to endogenous gonadotropin-releasing hormone (GnRH/LHRH). It stimulates pituitary gonadotroph cells to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Because continuous GnRH-receptor stimulation causes downregulation/desensitization, research and clinical use of gonadorelin has historically relied on pulsatile administration to better mimic the body's natural pulsatile GnRH release pattern and sustain LH/FSH output.

Research Profile

Half-Life

Very short and measured in minutes; exact estimates depend on assay and formulation

Onset

LH and FSH are commonly sampled 30-45 minutes after an IV diagnostic bolus

Administration Routes (Research)

IV in human diagnostic studiesPulsatile SC use in specialist historical protocolsCurrent U.S. gonadorelin labels located are veterinary

Reported Research Effects

Stimulates LH/FSH release via native GnRH receptor pathway
Pulsatile dosing sustains gonadotropin response; continuous dosing causes desensitization

Reported Research Side Effects

Flushing
Headache
Nausea
Transient pituitary-gonadal hormone changes
Repeated pulsatile use requires specialist monitoring

Data source: Human diagnostic study plus current DailyMed label-status review

Research Notes

Five duplicate unsourced SC fertility or TRT schedules were removed. Current DailyMed gonadorelin products found in the U.S. are animal drugs and must not be represented as human-approved products.
