What Kisspeptin-54 is
Kisspeptin-54 (metastin) is the 54-amino-acid form of the hypothalamic peptide kisspeptin, which acts on the KISS1R (GPR54) receptor to drive GnRH and downstream LH and FSH release. Academic human studies have given it intravenously, subcutaneously and intranasally to healthy volunteers, women with hypothalamic amenorrhoea and women undergoing IVF, where it was used to trigger oocyte maturation. It is not approved for any use and is prohibited in sport; this entry summarizes the published studies for research reference only.
Kisspeptin is the endogenous ligand of the G protein-coupled receptor KISS1R (GPR54); inactivating mutations of this pathway are associated with failure of reproductive function and infertility 1,5. Neuroendocrine action Kisspeptin acts at the hypothalamus to release an endogenous pool of GnRH, which in turn drives pituitary LH and FSH secretion 7. In humans, raising circulating kisspeptin-54 increased LH, FSH… How it works →

What the human evidence shows
We searched PubMed and ClinicalTrials.gov and found no human studies that administered Kisspeptin-54. The research described on its page is from cells or animals, and animal amounts do not translate to people.
How long did human studies run?
- Human studies ranged from single-session infusions to 2 weeks of repeated administration 1,3.
- Follicular-phase exposure over 1 week in healthy women 4.
Who was excluded from the studies
- No label exists, so no formal contraindications are defined 9.
Side effects reported in studies
- Moderate ovarian hyperstimulation syndrome1 of 31 (3.2%) single trigger vs 0 of 31 with additional administration · Women at high risk of OHSS undergoing IVF 7
- Moderate, severe or critical OHSS0 of 60 · Women at high risk of OHSS undergoing IVF 6
- Any side effect or adverse event (intranasal)None encountered · Healthy men and women and women with hypothalamic amenorrhoea 8

Supplies and handling
- Lyophilized vialSealed vial with the freeze-dried cake. Check the label, lot and the certificate of analysis before opening.
- Sterile diluentThe diluent named on the product documentation. Bacteriostatic water contains benzyl alcohol; sterile water does not.
- Graduated syringesSized to the volume being measured. U-100 insulin syringes are graduated in units where 100 units = 1 mL.
- Alcohol prep padsFor wiping vial stoppers before each puncture.
- Nitrile glovesClean gloves for aseptic handling.
- Sharps containerPuncture-resistant container for used needles.
Storage
No approved-product storage instructions exist. In one study a nasal-spray formulation was stable for up to 60 days at 4 degrees C 8; otherwise handling should follow the supplier's documentation.
- Lyophilized (unmixed) vials: typically stored cold and dry, away from light, as the documentation directs. Many are stable longer frozen.
- Reconstituted vials: typically refrigerated (about 2–8 °C), protected from light and not frozen.
- Bacteriostatic water contains benzyl alcohol, which inhibits bacterial growth in multi-use vials; sterile water has no preservative.
Handling mistakes and troubleshooting
- Added the wrong volume of diluent
- The concentration changes, not the amount of compound in the vial. Recalculate with the volume actually added and relabel the vial.
- Shook the vial and it foamed
- Let it settle in the refrigerator. Foam is a sign of agitation; some peptides aggregate when shaken. Note it on the label.
- The solution is cloudy or has particles
- Do not use it. Cloudiness can indicate incomplete dissolution, contamination or degradation. Record the lot and contact the supplier with the certificate of analysis.
- The powder cake looks melted or shrunken before reconstitution
- This can indicate the vial was exposed to heat or moisture. Record the lot and condition on arrival.
- Liquid sprayed back when the needle was removed
- Pressure built up in the vial. Withdraw a small volume of air while adding diluent to keep pressure neutral.
Regulatory status
- Status
- Not approved by the FDA or, in the sources reviewed, any other regulator. A Drugs@FDA / openFDA query for kisspeptin returned no application record 9. Kisspeptin-54 is not named in FDA's May 14, 2026 503A bulk substances list, where kisspeptin-10 is in category 2 (significant safety risks) 10. Human studies have been academic, investigator-led trials 5,7.
- United States (FDA)
- Not approved. A Drugs@FDA / openFDA query for kisspeptin returns no matching applications 9. Kisspeptin-54 is not named in FDA's May 14, 2026 503A bulk substances list; kisspeptin-10 is listed in category 2 10.
- Sport (WADA)
- Prohibited at all times. Section S2.2.1, testosterone-stimulating peptides in males, names kisspeptin and its agonist analogues 12.
