SNAP-8 is defined by an acetyl group at one end. Material where that step did not go to completion is 42 daltons light and is not the compound.

Order this testAn eight-residue peptide, acetylated at the N-terminus, sold into cosmetic formulation under the INCI name acetyl octapeptide-3. It is an extension of the shorter argireline peptide.
Acetylation adds 42 daltons and is a separate synthesis step. Incomplete acetylation leaves unmodified peptide mixed into the product at 1033 rather than 1075.
Forty-two daltons in a thousand is four percent — detectable by mass, invisible to anything else.
Cosmetic peptides are usually supplied as dilute solutions rather than lyophilised powder, often at one percent or less in a glycerin or water base. A quoted milligram figure may describe the solution rather than the peptide. Net peptide content resolves it.
Trade name, INCI name and sequence-based name are all in circulation for the same molecule, and the closely related argireline is often shelved beside it.

No. Lyophilised peptides travel safely at room temperature, which is how nearly all samples reach us.
An independent Ontario laboratory. Every certificate we issue names the facility that ran it — we are a testing service, not a laboratory, and we would rather say so than let you find out from the report.
You get the result. We do not soften findings, and we do not charge differently depending on what the analysis shows.
Yes. Every certificate carries an identifier that anyone can check against our records, including the vendor you bought from.
