How to Read a SNAP-8 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 SNAP-8, the informative checks are not the same as for a generic short peptide.
Overview
Check the weight near 1075 and that the cap is present (a missing cap shows up 42 lighter).
What SNAP-8 actually is
A short, capped cosmetic peptide — a longer relative of Argireline — studied for softening the look of expression lines by easing the nerve-to-muscle signal at the surface. A topical cosmetic research compound.
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 SNAP-8
What to check on the COA
Confirm the mass near 1075.3 Da and that the N-acetyl group is present (an unacetylated impurity would sit 42 Da lighter).
Unacetylated (-42 Da) related substance and deletion sequences.

What SNAP-8 is studied for
Studied for mimicking the N-terminus of SNAP-25 and competing in the SNARE complex that mediates neurotransmitter release.
Examined at the junction where nerve meets muscle, the mechanism of interest for expression-line cosmetic research.
Investigated as a topical cosmetic research peptide and compared with its shorter relative, Argireline.
