Kisspeptin
Reproductive peptide Limited evidence 3 cited studies 59 live vendors
Kisspeptin is a reproductive-axis signaling peptide, the product of the KISS1 gene, that acts on the KISS1R (GPR54) receptor and is studied in laboratory models for its role in regulating GnRH neuron activity and upstream control of the reproductive endocrine system. Multiple fragment forms (such as kisspeptin-10 and kisspeptin-54) are used as reference materials in neuroendocrine and receptor-signaling research. This index tracks research-use-only vendor pricing for Kisspeptin to help researchers compare cost across suppliers.
Evidence brief
Kisspeptin is a hypothalamic neuropeptide (encoded by the KISS1 gene, acting through the receptor GPR54/KISS1R) that stimulates gonadotrophin-releasing hormone and is described as a key regulator of the reproductive axis.

These figures are what pepmg still publishes about price: the floor, the middle, the spread and how many sources we track, computed from listings we captured first-party and refreshed on the same schedule as always. We no longer publish the individual listings or the sellers behind them.
Computed from 64 in-stock listings across 59 sources we captured first-party, with bulk vials, blends and statistical outliers excluded so the figures compare like with like. The spread is the highest tracked price divided by the lowest — how much the same milligram varies depending on where you look. The chart is the daily minimum; days we did not capture are left out rather than filled in.

- The Role of Kisspeptin in the Control of the Hypothalamic-Pituitary-Gonadal Axis and Reproduction PubMed ↗
The discovery of kisspeptin as a critical central regulatory factor of GnRH release has given people a novel understanding of the neuroendocrine regulation in human reproduction. Kisspeptin activates the signaling pathway by binding to its…
- Metabolic regulation of kisspeptin - the link between energy balance and reproduction PubMed ↗
Hypothalamic kisspeptin neurons serve as the nodal regulatory centre of reproductive function. These neurons are subjected to a plethora of regulatory factors that ultimately affect the release of kisspeptin, which modulates…
- Kisspeptin and Glucose Homeostasis PubMed ↗
Kisspeptin has well-established critical roles in the control of reproduction and fertility. Recently, evidence has emerged that suggests kisspeptin may have additional roles in the regulation of glucose homeostasis. Conflicting reports on…

▸ Why compare $/mg for Kisspeptin?
Per-mg prices for Kisspeptin vary because vendors differ in synthesis scale, stated purity, salt form and net-peptide content, and how they package and ship a hygroscopic lyophilized product. Comparing normalized $/mg across suppliers lets a researcher weigh headline vial price against documented purity and actual peptide mass, rather than paying more for a nominally cheaper vial.
▸ Reading the COA
For Kisspeptin, confirm identity by mass spectrometry against the expected monoisotopic/average mass of the specific fragment ordered (kisspeptin-10 versus kisspeptin-54 differ substantially), since fragment length is a common source of mislabeling. Check that HPLC purity is stated (commonly 95%+ or 98%+ for reference-grade material) with the trace attached, and look for a net peptide content figure and counterion identity. Likely impurities to watch for include truncated or deletion sequences, incompletely deprotected species, and TFA/acetate salt contributing to non-peptide mass.
