Type: N-acetylated octapeptide
Category: Cosmetic research
Alternate names: Acetyl octapeptide-3, acetyl octapeptide-3
Historical context
SNAP-8 extends the acetyl-hexapeptide pattern by Ala-Asp. The INCI name is acetyl octapeptide-3. Public sources do not all print the same molecular weight: the amide formula on PubChem is about 1075 Da, while another registry calculation is nearer 1034 Da. This page prints the sequence and CAS 868844-74-0, and it does not invent a purity to paper over that disagreement. Match the lot certificate.
Active research areas
Sequence Ac-Glu-Glu-Met-Gln-Arg-Arg-Ala-Asp-NH2.
CAS 868844-74-0. PubChem amide formula C41H70N16O16S, about 1075.16 g/mol.
A second public calculation lists a different mass. The lot record is the identity for a received unit.
Not acetyl hexapeptide-8 (Argireline).

Catalogue line
The only VaultLabs fill is [SNAP-8 10mg](/product/snap-8-10mg). It is not GHK-Cu and not Matrixyl. Papers about Argireline describe the shorter hexapeptide. They are cited on the monograph so a reader can see the relationship, and the citation note says they are not a SNAP-8 certificate. Do not file an Argireline chromatogram against this vial.
All VaultLabs materials are supplied strictly for in vitro laboratory and research use. Not for human consumption, medical use, or personal application.
Receiving
Cosmetic-peptide names collide in purchasing. Write acetyl octapeptide-3 or SNAP-8, the 10 mg fill, and the lot. The monograph is at [/compounds/snap-8](/compounds/snap-8). Receiving still uses [batch verification](/batch-verify) and a [documentation request](/request-documentation) when the public lot page is empty.
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.
