Kisspeptin Research Overview

Kisspeptin (also known as Metastin) is a neuropeptide encoded by the KISS1 gene. The 10-amino-acid C-terminal fragment, Kisspeptin-10, is the most potent endogenous activator of the GPR54 / KISS1R receptor on GnRH neurons in the hypothalamus, sitting at the very top of the reproductive hormone cascade.

Purity and Laboratory Testing

Lot AFL-KISS-10-2026-001 (tested 2026-04-22) of Kisspeptin was assayed by an independent laboratory using reversed-phase HPLC for purity and mass spectrometry for identity confirmation, returning 99.4% purity. The Certificate of Analysis shipped in the box matches the lot number printed on the vial.

Technical Product Information

Molecular formula C₆₃H₈₃N₁₇O₁₄, molecular weight 1302.5 g/mol, sequence Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH₂. Kisspeptin binds the KISS1R (GPR54) receptor on GnRH neurons, triggering pulsatile gonadotropin-releasing hormone secretion. This stimulates the anterior pituitary to release LH and FSH, which in turn drive endogenous testosterone production in males and estradiol/ovulation in females — without the suppressive feedback seen with exogenous hormones. Kisspeptin is supplied as lyophilized powder and is classified in our catalog under neuropeptide / hpg regulator for neuropeptide / hpg regulator work. Recorded research categories for this compound include hpg axis and gnrh pulse-generator research, fertility, ovulation and puberty studies, hypogonadism and low-testosterone protocols, pcos and reproductive endocrinology research. Handling notes: store at -20°c (freezer), protect the vial from light, and avoid repeated freeze–thaw cycles once reconstituted. Amino Fuel Labs publishes no dosing protocol for Kisspeptin: the compound is distributed for in-vitro and preclinical laboratory research only and is not intended for human or veterinary use.

Frequently Asked Questions

What is Kisspeptin used for in research?

Kisspeptin is researched as the master upstream regulator of the HPG axis. It stimulates pulsatile GnRH release, which drives LH, FSH and downstream testosterone or estradiol — making it a key tool in fertility, puberty and hypogonadism studies.

How is Kisspeptin different from HCG?

HCG mimics LH at the testicular receptor and bypasses the brain. Kisspeptin acts upstream at the hypothalamus, recruiting the body's own GnRH-LH-FSH cascade — a more physiologic, non-suppressive research pathway.

Is your Kisspeptin third-party tested?

Yes. Every vial ships with HPLC and Mass Spec verification at ≥99.4% purity and an itemized batch-specific Certificate of Analysis.

What is Kisspeptin studied for?

Kisspeptin appears in laboratory research covering fertility research, hormone optimization, hpg axis studies. All references describe in-vitro and preclinical study models only.

Does Kisspeptin include a Certificate of Analysis?

Yes. Each Kisspeptin lot ships with a batch-specific third-party Certificate of Analysis reporting 99.4% purity by reversed-phase HPLC alongside mass-spectrometry identity confirmation.

What form does Kisspeptin arrive in?

Kisspeptin is supplied as lyophilized powder in a sealed vial, packed with the lot documentation for the exact batch shipped.
