How to Read a Kisspeptin Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For Kisspeptin, the informative checks are not the same as for a generic short peptide.
Overview
Check the weight near 1302 and look for a small extra peak 16 heavier, which signals light damage.
What Kisspeptin actually is
A ten-part peptide that sits at the very top of the body's fertility and sex-hormone signalling, telling the brain to start the hormone cascade. Studied around fertility, libido, and how that cascade is regulated.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Assays that are informative for Kisspeptin
What to check on the COA
Confirm the mass near 1302.5 Da and scan for a companion peak 16 Da heavier, which indicates tryptophan oxidation.
Tryptophan-oxidised (+16 Da) related substance and deletion sequences.

Every batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity). Enter a lot number to pull the COA for the exact vial in front of you.
What Kisspeptin is studied for
Studied as the upstream trigger of GnRH release and the downstream LH and FSH signalling cascade.
Examined as the endogenous ligand for the KISS1 receptor in reproductive neuroendocrine models.
The parent KISS1 product was first characterised in cancer-metastasis research, a separate strand of the literature.
