Deslorelin vs Triptorelin
A neutral, side-by-side comparison of two performance & growth hormone peptides — their mechanisms, dosing ranges, administration routes, side effects, and research evidence. For research and educational purposes only.
Deslorelin
Potent GnRH super agonist approximately 100× more potent than native GnRH. Used in veterinary medicine for estrus suppression and in human medicine for precocious puberty treatment. In research protocols, used for pituitary desensitization to reset the HPG axis or induce controlled medical suppression of sex hormone production.
Full profileTriptorelin
Potent synthetic GnRH agonist approximately 100× more potent than native GnRH. Used clinically for prostate cancer, endometriosis, and precocious puberty via sustained suppression. A single low dose (100mcg IM) is studied as a 'PCT restart' strategy that exploits the initial LH/FSH flare before receptor desensitization sets in.

Key differences
- Administration: Deslorelin — Subcutaneous implant (veterinary), Subcutaneous injection; Triptorelin — Intramuscular injection, Subcutaneous injection.
- Frequency: Deslorelin is typically Daily SC for continuous suppression; single or short course for pituitary reset; Triptorelin is Single-dose for PCT restart; every 2–4 weeks for sustained suppression (clinical).
How each works
Deslorelin
Deslorelin produces a robust initial LH/FSH surge (flare effect) followed by profound, sustained pituitary desensitization with continued exposure. This biphasic response is consistent across all high-affinity GnRH super agonists. The flare phase is exploited for reproductive timing in veterinary medicine; the desensitization phase creates the clinical suppression used in precocious puberty and research HPG axis reset protocols.
Triptorelin
Triptorelin produces a biphasic response: an initial agonist surge of LH and FSH (the 'flare effect') followed by complete pituitary desensitization with continued use. The single-dose PCT protocol leverages only the initial flare to jumpstart testosterone production. Clinical data supports LH surges of 10–20× baseline within hours of the first dose.
