What is Snap-8?
SNAP-8 is an eight-residue peptide, capped at both ends. Its cosmetic-ingredient name is acetyl octapeptide-3. The eight residues are copied from one end of SNAP-25, a protein that helps build the SNARE complex inside nerve cells. A shorter peptide called Argireline is sold separately across the industry. It is the same sequence minus the last two residues. The two are catalogued, studied and sold as different molecules, and the shorter one has far more published work behind it.

Snap-8 Research & Reference
What Snap-8 does in published studies, and how to work with it in the laboratory, are covered in full on two dedicated pages rather than summarised here, so neither the evidence nor the handling detail is cut short.

Frequently Asked Questions
Is Snap-8 third-party tested for purity?+−
Yes. Every batch of Snap-8 is tested by an independent third-party laboratory using HPLC and MS-UPLC, confirming purity and mass identity before the batch is released. Pure Peptides does not test its own material.
Can I see the Certificate of Analysis before buying?+−
Yes. The Certificate of Analysis for the batch currently in stock can be viewed and downloaded directly on this page, before you place an order. Each certificate states the batch number, the measured purity, and the date of analysis, and can be verified independently with the issuing laboratory using the report number it carries.
What does "Research Use Only" mean?+−
It means Snap-8 is supplied for in-vitro laboratory research and for no other purpose, and must not be administered to humans or animals. Snap-8 is legal to purchase in the United States for in vitro and non-clinical laboratory research. In the United States, cosmetic products and ingredients other than color additives do not require FDA approval before going on the market. No approved drug application names acetyl octapeptide-3 as an active ingredient. This material is supplied for laboratory research only and is not for human consumption. Snap-8 is not a scheduled substance under the Controlled Substances Act. Sold strictly for qualified research use, not human or veterinary administration.
How is Snap-8 shipped and stored?+−
Snap-8 ships from US stock with cold-chain packaging and full tracking; orders placed before noon EST on business days are typically dispatched the same business day. On arrival, store the lyophilized powder at -20°C or below, dry and protected from light.
What is the difference between SNAP-8 and Argireline?+−
Argireline is the trade name of acetyl hexapeptide-3, the six-residue peptide Ac-EEMQRR-NH2. SNAP-8 is acetyl octapeptide-3, the same six residues with alanine and aspartate added at the amidated end. They are catalogued, sold and studied as different molecules. PubMed indexes 45 records under the hexapeptide's names and two under this one.
How much published research is there on acetyl octapeptide-3?+−
Two indexed records name it. In both, it was one ingredient among several in a microneedle patch, and in neither was it tested on its own. Both were run or co-run by companies with a commercial interest in the product tested. The Snap-8 research article cites both and states exactly what each measured. Two further published human studies name it only in their full text, and the article covers those too. Both tested a multi-ingredient product in people with no control arm, and both were funded by a company that employed one or more of their authors.
