What to verify when procuring research-grade peptides
For Mazdutide research, confirm: (1) purity specification and method (HPLC — not just “≥98%”); (2) COA issuer — independent labs (Janoshik, Intertek) vs in-house; (3) peptide identity by MS (not just HPLC retention time); (4) domestic shipping availability for your region; (5) batch-to-batch consistency records if running multi-cohort studies.
