Historical context
Matrixyl is a trade-style name for palmitoyl pentapeptide-4. The sequence that matters at receiving is Pal-KTTKS, CAS 214047-00-4. Drop the palmitoyl chain and the substance is a different, more polar pentapeptide. Published topical studies of the lipopeptide are cited so the identity is traceable. They are not a claim that this vial changes skin.
Active research areas
Sequence Pal-Lys-Thr-Thr-Lys-Ser.
CAS 214047-00-4.
The palmitoyl chain is part of the identity. Unmodified KTTKS is a different substance.

Receiving
Write palmitoyl pentapeptide-4 or Matrixyl, 10 mg, and the lot. A certificate for GHK-Cu or for SNAP-8 does not release this vial.
Each sealed unit carries its own lot number. The current catalogue certificate for that lot is published on the batch page and states purity of at least 99.8 percent on the same VaultLabs template used for the rest of the lyophilized catalogue. A certificate for one fill does not qualify another fill. A certificate for a blend does not qualify a single-sequence vial that happens to share part of a name. Do not copy a purity figure from a different product, from a photograph of another vial, or from a paper into the receiving file. Match the printed name, the nominal mass and the lot number on the vial to the published record. If those three do not agree, hold the unit and ask for the document that belongs to that unit before it leaves quarantine. Enter the printed lot at batch verification.
