What is SNAP-8?
SNAP-8 is an octapeptide — eight residues — also sold as acetyl octapeptide-3. Its sequence is modelled on the N-terminal end of SNAP-25, a protein involved in vesicle fusion, from which it takes its name.
Classification
| Type | Peptide |
| Chain length | 8 amino acid residues |
| Family | SNAP-25 fragment analogue |
| Origin | Developed as an extension of acetyl hexapeptide-8, from the 2000s |
| Supplied as | Lyophilised powder in a sealed vial |
It is an extended version of acetyl hexapeptide-8, better known by the trade name Argireline: two additional residues on the same design. It is a cosmetic-sector peptide rather than a research compound in the sense most of this range is, and it is usually supplied and discussed in that context.
Where it sits by length
At 8 residues, SNAP-8 is a short chain — an oligopeptide by the usual convention. The boundary is a convention, not a rule of chemistry — chains up to roughly fifty residues are generally called peptides.
What this page does not cover
Nothing here describes what SNAP-8 does, what it is used for, or whether it is safe. We publish analytical results and ship parcels; we give no guidance on dosing, preparation or use, and that applies to our reference pages as much as to the product pages. The person to ask about any of that is a registered prescriber.
Where it came from
SNAP-8 is a cosmetic-sector peptide, and an extension of an earlier one from the same company.
The 2000s — Barcelona, Spain. When was SNAP-8 created?
