Semaglutide's purity and identity are documented with the same two-method approach used across research peptides.
The measurements
HPLC reports purity (e.g. ≥98%); mass spectrometry confirms identity against the expected mass (C187H291N45O59). A batch-specific COA ties results to your lot; third-party testing adds independence.
V8 supplies semaglutide at ≥98% HPLC with a batch COA: Semaglutide research vials.
