Source: PepIndex, an independent index of research-peptide vendors. No vendor can pay for a rank, every score is computed by a published formula, and every figure links to the document it was read from.
Evo Labs Research has the most checkable SNAP-8 testing in this index: 1 lot assayed by Kovera Labs, the newest on 29 May 2026. The lowest listed price is $3.00 per mg at Amino Club, against a peer median of $4.00. 9 vendors carrying SNAP-8 are compared below. 2 publish at least one certificate naming a checkable laboratory, 4 lot records are on file, and none is an independently commissioned assay. Figures are PepIndex's own: it is an independent index of research-peptide vendors, no vendor can pay for a rank, and each figure links to the certificate it was read from.

Independent assays
No independently commissioned assay of SNAP-8 is on file. All 4 records below were published by the vendor that sells the product, naming the laboratory shown. PepIndex does not yet commission its own assays, so nothing on this page establishes what is in a vial beyond the vendor’s own certificate. A record moves into this section the moment an assay commissioned by anyone other than the seller is indexed.

Score breakdown
The score has two halves: the research base — how long the compound has been studied and how much has been published — and the quality of the evidence the market produces for it, aggregated across every vendor that carries it: assayed purity, lot-to-lot consistency, readable third-party certificates and those vendors’ review record. It measures the evidence base, not the merits or safety of the substance.
Studied since 2020 — 6 years of published research
How long the compound has been studied. Fifteen years or more of published literature earns full marks; a newer compound earns less.
2 publications indexed in PubMed
The volume of published literature located. Full marks at fifty or more publications.
Mean assayed purity 99.6% across 4 certificates
Average assayed purity on the certificates published by vendors that carry this compound. Full marks at 99.5%+, nothing at 95% or below.
±0.29 pts purity across lots, mean label deviation 6.2%
How tightly assayed purity and labeled-versus-actual mass hold across different lots. Rewards reproducible manufacturing.
9 of 9 listing vendors publish an accessible certificate policy
Whether the vendors carrying this compound publish per-lot certificates anyone can read without an account.
2 of 4 certificates from a recognised independent lab
Share of certificates issued by a recognised third-party testing lab rather than an unnamed or self-named one.
What is SNAP-8?
An eight–amino-acid peptide extension of the cosmetic peptide argireline, studied topically in relation to the appearance of expression lines.
Studied in published research for the cosmetic appearance of expression lines.
Regulatory status
Labeled by vendors for laboratory research use only. Not approved as a medicine in the United States, United Kingdom, or European Union.
What the research examines
The areas of published research this compound appears in. These describe what the literature has studied — never a claim of benefit, effect or suitability for any use.
Published research
Published work is largely in vitro and in cosmetic formulation research. PepIndex does not evaluate clinical significance and does not describe administration.

Aging skin is a gradual physiological process associated with functional and structural changes of the skin. Both intrinsic and extrinsic factors influence skin aging by the involvement of multiple pathways. Restoring natural skin conditions requires a multi-targeted approach. Recent developments in both bioactive peptides and microneedle delivery system have presented an opportunity for tackling premature skin aging. This study was aimed at evaluating the dermal tolerability…
Evidence digest
What the research on SNAP-8 actually shows
The indexed literature on SNAP-8 includes human clinical or observational records (1 human-clinical or observational record). This digest describes the shape of that evidence and links the records behind it. It does not judge whether SNAP-8 is safe or effective for any purpose, and nothing here is medical advice — the material sold by the vendors in this index is labeled for laboratory research use only.
