Buyer's Guide
How to qualify a peptide API supplier
Price per gram rarely tells the full story. These are the six checkpoints experienced procurement and QA teams review before approving any peptide source — and the data we prepare to answer them.
HPLC Purity & Related Substances
Ask for chromatograms, not just a purity figure. Individual impurities and deletion or truncated sequences matter as much as the main peak.
Identity by Mass Spectrometry
Confirm molecular weight by MS and, for complex analogues, amino acid analysis or peptide mapping to verify the sequence.
Net Peptide Content & Counter-Ion
Purity is not content. Check peptide content, acetate or TFA counter-ion levels and water content to calculate true dosing.
Residual Solvents & Endotoxin
For injectable end products, request residual solvent results, bioburden and bacterial endotoxin data aligned with your specification.
Stability & Storage Data
Lyophilized peptides are sensitive to moisture and temperature. Review stability information and confirm cold-chain shipping terms.
Scalability & Documentation
Verify the supplier can repeat the process at commercial scale and support the regulatory documents your market requires.
TipShare your target specification when you request a catalog — our team will confirm which documents are available for each product.
