About Kisspeptin

What it is

Kisspeptins are short peptides made from the KISS1 gene, sold as kisspeptin-10, -13, -14 or -54 depending on length. They were first described as metastin for a role in suppressing tumor spread, and were later found to be a key trigger of puberty and fertility.

How it works

  • Binds the kisspeptin receptor (KISS1R, also called GPR54) on GnRH neurons in the hypothalamus.
  • This releases GnRH, which makes the pituitary release LH and FSH, the signals that drive ovulation and testosterone production.

Kisspeptin: more questions people ask

Which Kisspeptin vendors have lab reports confirmed by the testing lab?

26 as of November 12, 2026. Those whose confirmed reports cover both purity and toxicity: BioLongevity Labs, Hydro Research Peptides, Lost Coast Aminos, Next Level Compounds, Pinnacle Peptide Labs, PeakForce Labs, Ascension Peptides and NOVA Labs and 6 more. PepAssess matches each report to the issuing lab's own public record, not the vendor's copy.

How can I tell if a Kisspeptin certificate of analysis (COA) is real?

Look the report up in the testing lab's own records — most labs that test peptides publish a lookup by report ID, QR code or lot number. PepAssess does this for every Kisspeptin report it finds: as of November 12, 2026, 26 of the 27 sellers publishing a Kisspeptin report had one the lab confirmed.

How much does a vial of Kisspeptin cost?

As of November 12, 2026, a 10 mg vial of Kisspeptin costs a median $55 across the 183 sellers PepAssess found with one in stock (lowest $19.25); a 5 mg vial, a median $45 across 65 sellers (lowest $12.45). Each seller's lowest in-stock price for that size counts once; prices come from each seller's own store and exclude shipping and discounts.

Can you buy Kisspeptin as a nasal spray or a pen?

Yes. As of November 12, 2026, 375 of the 44 Kisspeptin sellers PepAssess lists sell a vial; 26 a nasal spray and 24 a pen or pre-filled form. Counts come from each store's own product names. A lab report covers the product and batch it names — check that it's for the form you're buying.

How do I know if a Kisspeptin seller is legit?

Check what the seller can show. As of November 12, 2026, PepAssess checks every Kisspeptin seller for three things: a Kisspeptin lab report that the testing lab confirms on its own records (26 of 44), card payments, which let you dispute a charge (36 of 44), and a published street address — not a mailbox or registered agent (18 of 44). Each seller's PepAssess profile shows which of these it has.

Are there Kisspeptin coupon codes?

Yes. PepAssess lists coupon codes for 44 vendors selling Kisspeptin: BioLongevity Labs: PEPASSESS (15% off), Hydro Research Peptides: PepAssess20 (20% off), Lost Coast Aminos: PEPASSESS (10% off), Myoasis Labs: pepassess (20% off), Bench Grade Peptides: PEPASSESS (10% off), Next Level Compounds: pepassess (30% off) and 38 more.
