- ISO 17025 HPLC + MS every batch
- Public COA archive with chromatograms
- Lot-specific matching vial labels
- ≥98.0% verified MT-2
- Gold standard for research-grade verification. Publicly accessible documentation eliminates trust-based purchasing
- Supplier B
- 'In-house quality control'
- COA provided after purchase only
- Generic COAs not lot-matched
- 95–97% claimed (unverified)
- Lacks independent oversight. Purity claims cannot be validated before ordering
- Supplier C
- Third-party tested 'select batches'
- Representative COA from 2024
- No batch number on product labels
- 96–99% (inconsistent)
- Partial verification insufficient for research. No guarantee received batch was tested
- Supplier D

- Unacceptable for controlled research. Dosing accuracy cannot be confirmed
- The comparison makes the distinction clear: suppliers providing ISO-accredited third-party testing with public COA access and lot-specific traceability eliminate the guesswork that compromises research protocols. Real Peptides' verification standards meet this threshold across every production batch. HPLC and mass spectrometry data published before purchase, with chromatograms showing integrated purity ≥98% and molecular weight confirmation at 1024.2 Da for acetylated MT-2.
