Public COA index

Peptide Testing Labs & COA Database

Search 6,435 public COAs linked to visible peptide listings. Browse by peptide, vendor, lab, lot, test date, or reported purity.

A record means we matched a stored COA to a listed product. It does not grade product quality. How to read a COA · New to peptides? Start with the beginner’s guide

Coverage

How many in-stock products have a recent COA?

We count a peptide sold by one vendor as one product.

Stage 1

3,303

Listed

Starting count

Every peptide offered by every vendor in the public catalog.

Stage 2

2,889

In stock

87.5% remain

Listed products currently marked in stock.

Stage 3

1,620

With a COA

56.1% remain

In-stock products matched to a COA in this index.

Stage 4

1,323

Tested in past year

81.7% remain

Those COAs with a printed test date in the past 12 months.

Missing COAs count as gaps. COAs without a printed test date do not count as recent.

Current listings matched to indexed COAs and recorded prices.

Recent changes

Latest certificate updates

These are the newest eligible certificate updates in the index. A vendor may have testing that we have not indexed.

Peptide, laboratory, date, lot, and purity fields are transcribed from the certificate. “On file” describes our records and carries no product-quality or safety rating.

Data quality

How this index works

We publish a narrower set of records than we collect.

Public scope

Only stored documents classified as COAs and matched to a catalog peptide are eligible. The public view also requires a visible, non-wholesale vendor–peptide market pair.

Current record

We show the newest eligible certificate for each vendor–peptide pair. We set aside future-dated records so they cannot replace a valid current record.

Age and fields

Records more than 18 calendar months old are labeled as older. Test date, lab, lot, compound, and purity are transcribed fields and may be absent.

Names and counts

Printed laboratory text remains visible. We group obvious name variants only for counting. An uncovered listing may still have testing that is not in our index.

Scope note: A record appears on file after our pipeline identifies the document as a certificate of analysis and matches its printed compound to a catalog peptide. The record cannot prove authenticity, chain of custody, sterility, product safety, or suitability for use.

Among current records, 96.9% include a test date, 99.1% name a laboratory, and 85.2% report a purity value. Test dates in the current index run from July 2021 through September 2026.
