- Every research peptide ships with a certificate of analysis (CoA). The question researchers should ask: who generated that CoA, and when? Real Peptides commissions independent third-party HPLC and mass spectrometry analysis for every Adamax batch within 7 days of shipping. The testing lab has no financial relationship with the manufacturer and uses reference standards traceable to NIST (National Institute of Standards and Technology).
- Competitors typically provide CoAs generated by the contract manufacturer during initial synthesis. Sometimes 90–180 days before the peptide reaches the customer. Those certificates reflect the purity at the time of bulk production, not at the time of purchase. Peptide stability during that interval depends on storage temperature, light exposure, humidity control, and packaging atmosphere. A peptide that tested at 99.2% purity in March may test at 97.8% in June if stored improperly.
- Independent verification catches degradation that internal testing misses. In our experience working with research institutions, the most common quality failure isn't contamination. It's oxidation of methionine residues during storage, which doesn't show up in basic purity testing but absolutely affects biological activity. Third-party labs using LC-MS (liquid chromatography–mass spectrometry) detect these modifications; manufacturer self-testing using UV-based HPLC often doesn't. Real Peptides uses both methods for Adamax verification because the combination provides a complete molecular fingerprint.
