  • Research-Grade (Real Peptides)
  • ≥98% via HPLC/MS
  • Mass spectrometry, third-party COA
  • Preclinical studies, mechanism investigation
  • Gold standard for controlled research. Reproducible results require this level of purity
  • Clinical-Grade (Pharmaceutical)
  • ≥99.5% via cGMP
  • FDA batch verification, sterile manufacturing
  • Human trials under IND application
  • Required for patient administration in formal trials. Higher cost, regulatory oversight
  • Marketed Supplements
  • Often <90%, unverified
  • Label claim only, no independent testing
  • Consumer products, minimal regulation
  • High risk of degraded or mislabeled product. Insufficient for meaningful research
  • Veterinary-Grade
  • 85–95%, variable
  • Supplier internal testing only
  • Animal studies, agricultural use
  • Acceptable for large-animal models but inconsistent batch-to-batch
