A legitimate peptide vendor publishes third-party certificates of analysis, labels products research use only, is transparent about testing and sourcing, uses secure checkout, and avoids medical claims. Missing any of these is a warning sign.
The legitimacy checklist
- Published COAs: batch-specific certificates of analysis you can actually read.
- Third-party testing: analysis by an independent lab, not just in-house.
- Clear RUO labeling: honest about intended use and storage.
- No medical claims: a vendor promoting human use is a red flag.
- Transparency: real contact info, clear policies, secure payment.
- Consistent quality: documented high purity across batches.
The red flags
Be cautious of vendors that cannot produce a COA, make health or dosing claims, hide behind vague sourcing, or pressure you with hype. Those are the signals that a supplier is cutting corners somewhere that matters.

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.
