COAs & information
Proof of quality for every peptide we sell.
A certificate of analysis is the laboratory record for one specific batch — its identity, its net mass and its purity. Ours are produced by third-party labs and filed against the batch printed on your vial.
How to read a COA
Three things to check.
A certificate is only useful if it belongs to the material in front of you. These three checks take under a minute.
Find the batch number
It is printed on the vial label and repeated on your order confirmation. Every certificate belongs to one batch — not to a product line.
Match it to a certificate
Each report below names the compound, the testing laboratory and the date the sample was run.
Read the two numbers that matter
Identity confirms the compound is what the label says; purity states how much of the sample is that compound.

Authenticity, on the record.
Third-party test reports for current batches. Search by compound or batch number, and open any certificate to read it at full size.

No certificate matches that search
Try the compound name on its own, or the batch number printed on your vial. If the batch is not filed here yet, send it over and we will forward the certificate.

FAQs
About our certificates.
The questions researchers ask us most about testing, labs and verification.
This page shows certificates proving our peptides’ authenticity, net mass, and purity.
All of our COAs are either from batches tested by PepLair Research (you may see Javik’s Junction on older ones — that was our previous name), from partners such as Grey Axis Research or Mrs. Goodlife Goodies, or from the vendor themselves, such as Uther.
Every product sold here is tested. The tests confirm that what you ordered is what you receive, and that it meets the standard we require before anything is listed. They are also how we stay transparent about the products we sell.
Our COAs come from trusted third-party laboratories, and we keep expanding the labs we work with as more products become available.
Yes. Every product carries the COA matching the batch that was tested for it. We will always be transparent about where our peptides came from and where they were tested.
Some certificates carry a code you can check on the laboratory’s own website; others carry the signature of the technician who ran the test. If you want more detail about a lab or a specific report, ask us and we will provide it.
Authenticity
How to know a certificate is real.
A genuine COA names the testing laboratory, carries a test date, states the method used, and refers to a batch — not to a product line. If any of those is missing, the document tells you nothing about the vial in your hand.
If a certificate you received does not match the batch on your label, contact us and we will re-issue it.
Independent laboratories
Testing is commissioned from labs with no commercial stake in the result.
Per batch, not per product
One certificate covers one batch. New batch, new test, new document.
Kept on file
Certificates stay available after purchase, so a record written up months later can still cite them.
