Healing & Repair Peptide Testing
Tissue-repair peptides are typically short and high-purity, but the category sees enormous counterfeit pressure. We confirm sequence by MS/MS, measure copper stoichiometry for GHK-Cu, and screen for endotoxin on every injectable.
Recommended Panel
- ✓RP-HPLC purity
- ✓MS/MS sequence confirmation
- ✓ICP-MS (Cu for GHK-Cu)
- ✓Endotoxin (LAL)
Common Impurities to Watch For
Deamidation of Asn/Gln, missing/extra residues, incorrect copper:peptide ratio (GHK-Cu), residual TFA.
