## Description

Here Kisspeptin-10 comes as a pre-mixed aqueous solution in an amber bottle with a metered nasal pump, instead of as a lyophilised vial. The peptide is the C-terminal decapeptide of the KISS1 gene product — an RFamide-family agonist of KISS1R (formerly GPR54) that acts upstream of GnRH neurons within the hypothalamic–pituitary–gonadal axis.

The molecule matches the vial product; only the format changes. With the solution already made up, there is nothing to weigh, reconstitute or dilute, and every press releases a set volume — ideal for intranasal delivery and mucosal-absorption studies, where reproducible spray volumes matter more than fine adjustments of mass. The downside is that a peptide in water is less stable than a sealed lyophilised cake, so the in-use period is shorter and the bottle must be refrigerated.

## Frequently asked questions

### What distinguishes the spray from the lyophilised vial?

Nothing about the molecule. The spray is a pre-mixed solution in a metered pump, so no reconstitution is needed — at the cost of a shorter usable life and compulsory refrigeration. The vial offers finer concentration control and far longer storage stability.

### How much peptide does a bottle hold?

10 mg of Kisspeptin-10 in the 15 mL bottle and 20 mg in the 30 mL bottle — about 0.67 mg per millilitre in both. A primed pump usually releases around 0.1 mL per press, which is roughly 67 micrograms of peptide.

### Which purity documents can I get?

The Kisspeptin-10 used for filling is HPLC-tested to ≥99% purity with identity verified by mass spectrometry, and a certificate for your lot is available. It covers the peptide raw material that went into the specific fill you receive.

### What is Kisspeptin-10's target?

KISS1R (also called GPR54), a Gq/11-coupled receptor found on hypothalamic GnRH neurons. Acting there puts it upstream of the reproductive axis, which is why it features in studies of the HPG axis, puberty onset and gonadotropin pulses.

### Can I freeze the bottle to make it last longer?

No. Freezing can crack the glass, warp the pump and stress the peptide as solutes concentrate at the ice front. Keep it upright at 2–8 °C out of direct light, and plan your study around the limited in-use period instead.
