Gonadorelin vs Epitalon

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Gonadorelin

Gonadorelin is a synthetic form of gonadotropin-releasing hormone (GnRH). It stimulates the pituitary to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH), supporting natural hormone production.

Side-by-Side Comparison

AspectGonadorelinEpitalon
MechanismBinds to GnRH receptors in the pituitary gland, triggering pulsatile release of LH and FSH. This stimulates testicular or ovarian function and natural sex hormone production.Stimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production and circadian rhythms.
Typical DosageMen: 100-200mcg subcutaneously 2-3 times daily. Women (fertility): Per clinical protocol. HRT support: Often combined with other therapies.Typical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year.
AdministrationSubcutaneous injection. Pulsatile administration mimics natural GnRH release patterns. Often used during or after testosterone therapy.Subcutaneous or intramuscular injection. Usually administered in cycles rather than continuously.
Side EffectsHeadache, flushing, injection site reactions. In women may cause ovarian hyperstimulation. Generally well-tolerated.Generally well-tolerated. May affect sleep patterns initially.
