To avoid contaminating peptides in the lab: wipe vial stoppers with alcohol, avoid touching the needle, use bacteriostatic water, add the diluent gently, and refrigerate reconstituted solutions.
Clean handling basics
- Wipe the stoppers of both the peptide vial and the bacteriostatic water with an alcohol swab before inserting a needle.
- Do not touch the needle or let it contact any non-sterile surface.
- Use bacteriostatic water, whose preservative limits bacterial growth over a solution's life.
- Add diluent gently and swirl rather than shake.
Storage keeps it clean
Once reconstituted, keep the solution refrigerated and out of light, and use it within its stable window. Good storage is part of contamination control.

Every Axis compound is third-party tested to 99.4%+ purity, with a certificate of analysis on every batch.
Signs of a problem
Cloudiness, discoloration, or particles in a once-clear solution can indicate contamination or degradation. Any of these is a reason to discard it.
Key takeaways
- Wipe vial stoppers with alcohol before inserting a needle.
- Do not touch the needle or non-sterile surfaces.
- Use bacteriostatic water and add diluent gently.
- Refrigerate reconstituted solutions; discard if cloudy.
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.
