Choosing a research-peptide supplier is a purity-and-transparency problem. This is our recommended checklist.
The 7-point checklist
1. HPLC purity ≥99% on the exact batch shipped
2. COA available on request — no gatekeeping
3. Lyophilized presentation for stability
4. Batch traceability to the manufacturing lot
5. Tracked shipping with cold-chain where required
6. Clear research-use labeling on every vial
7. Responsive support — real humans, real turnaround
