Choose a supplier that publishes third-party certificates of analysis, documents high purity, labels products research use only, is transparent about testing and policies, and keeps descriptions honest and free of medical claims.
The criteria that matter
- Verifiable COAs: batch-specific, ideally third-party, and easy to find.
- Documented purity: a clear purity figure, commonly 99%+.
- Honest labeling: research use only, no human-use claims.
- Transparency: real contact info, clear policies, secure checkout.
- Consistency: quality that holds up batch after batch.

- The top factor is verifiable, third-party, batch-specific COAs.

A note on research use
The peptides supplied by Axis Peptide Labs are reference compounds for laboratory and research use only. They are intended for qualified researchers working in academic, institutional, and analytical settings. They are not drugs, foods, cosmetics, or medical products, and they are not intended for human or veterinary consumption. Documented identity and documented purity are what matter most when sourcing a compound, both of which are published on the Axis certificates of analysis page.
