In the United States, Kisspeptin is sold strictly for laboratory and research purposes only. It is not approved by the FDA for human consumption and is not sold for that purpose. Regulatory status varies by jurisdiction — buyers are responsible for compliance in their own region.

Kisspeptin-10 is the C-terminal decapeptide of the KISS1 gene product that activates KISS1R (GPR54) on hypothalamic GnRH neurons, the master upstream trigger of the reproductive (HPG) axis. New-U supplies Kisspeptin as research-grade reference material for laboratory and in-vitro or animal-model investigation only. Mechanism, pharmacokinetics and study context are summarised on the Kisspeptin research profile. Not for human use.

Reconstitution volumes and dosing reported in the literature for Kisspeptin are described in research-model terms only. New-U Research Compounds supplies Kisspeptin strictly for laboratory research and does not provide human-use dosing guidance. Reconstitution math and study-reported ranges are covered on the full research profile.

Lyophilised Kisspeptin is reconstituted with bacteriostatic water — sterile water with 0.9% benzyl alcohol, the standard multi-use diluent for research peptides. New-U supplies USP-grade bacteriostatic water at https://new-u.io/peptide/bacteriostatic-water, and a free reconstitution calculator at https://new-u.io/tracker/calculator works out the volume for any peptide. Supplied for laboratory research only — not for human use.

Yes. Kisspeptin can be ordered online directly from New-U Research Compounds with card or cryptocurrency, shipped direct from source discreetly worldwide. Delivery is approximately 6–14 business days worldwide. Free shipping applies to orders over $300.

Kisspeptin ships in 10-vial research packs as standard, in 4 pack sizes — the larger mg vials lower the per-mg cost. Multi-pack orders get direct-from-source pricing and free shipping over $300. For wholesale or recurring laboratory-supply volumes, contact New-U Research Compounds at https://new-u.io/contact.

For research-grade Kisspeptin, verify four things: (1) independent third-party purity testing with a batch-linked Certificate of Analysis — New-U uses Janoshik Analytics and Freedom Diagnostics at >99% HPLC; (2) lyophilised material with documented storage and handling; (3) transparent direct-from-source pricing rather than marketplace markup; and (4) clear research-use-only framing. New-U Research Compounds meets all four at https://new-u.io/peptide/kisspeptin.

Kisspeptin-10 is the active C-terminal decapeptide of the KISS1 gene product (metastin). It works by binding KISS1R (GPR54), a Gq/11-coupled receptor on hypothalamic GnRH neurons, triggering phospholipase-C signalling and a calcium rise that makes those neurons fire and release GnRH. That GnRH pulse then drives pituitary LH and FSH secretion, placing kisspeptin at the very top of the reproductive hormone cascade.

A GnRH agonist acts directly on the pituitary side of the cascade. Kisspeptin acts one step earlier, on the GnRH neurons in the hypothalamus that release GnRH in the first place. That upstream position is why researchers use it to study the natural, physiological control of the reproductive axis rather than overriding it.

Controlled human physiology studies report that exogenous kisspeptin raises circulating LH (mean increase ~2.75 IU/L in one trial) and, more modestly, FSH, without altering downstream estradiol, progesterone or testosterone over short study windows. Randomised clinical trials in men and women with hypoactive sexual desire disorder also found that kisspeptin modulated activity in sexual-processing brain networks. These are published research findings, not human-use claims — kisspeptin is supplied for laboratory research only.

Kisspeptin-54 (metastin) is the full-length peptide; kisspeptin-10 is its C-terminal ten-amino-acid fragment. Both bind the same KISS1R receptor through the shared C-terminal sequence. Kisspeptin-10 is shorter and shorter-acting (a circulating half-life on the order of minutes), while kisspeptin-54 circulates longer, which is why studies pick one or the other depending on whether they need a brief pulse or sustained exposure.

The KISS1 gene was originally discovered as a metastasis-suppressor gene, and its product was named metastin before the reproductive role of its receptor (GPR54/KISS1R) was understood. Kisspeptin and metastin refer to the same molecule.

They act at opposite ends of the same axis. Kisspeptin acts at the top, on hypothalamic GnRH neurons, recruiting the body's own LH/FSH release in a physiological way. hCG acts at the bottom, directly on the gonad via the LH/CG receptor, mimicking the LH surge. Researchers choose kisspeptin to study upstream, natural control and hCG to drive direct gonadal stimulation.

Keep the lyophilised powder frozen at −20 °C. After reconstitution with bacteriostatic water, refrigerate at 1–6 °C and protect from light. As with most research peptides, avoid repeated freeze-thaw cycles of the reconstituted solution. This is laboratory handling guidance only.
