- How is each lot tested?
- An independent laboratory tests every lot before it is released for sale: identity by LC-MS, purity by HPLC, net peptide content by quantitative HPLC and bacterial endotoxin by LAL. A lot cannot be offered on this site until those results and the laboratory's report are on its lot record.
- How do I check a certificate of analysis?
- Each lot record names the testing laboratory and, where the laboratory offers one, its verification link and key. Use them at the laboratory's own site to confirm the report matches what we publish. Our lab-testing page explains each test and what a certificate does and does not show.
- How should the material be stored?
- Lyophilized, at −20 °C for long-term storage or 2–8 °C short-term, protected from light and moisture. Allow the vial to reach room temperature before opening. Each lot's retest date is on its record.
- Do you provide protocols, reconstitution or dosing information?
- No. We do not provide protocols, reconstitution, administration or dosing information, and we do not answer questions about use in humans or animals. We are glad to help with storage, documentation and COA verification.
We do not sell solvents, diluents or injection supplies.
