Guides
Research peptides sit outside pharmaceutical regulation, which puts the burden of verification on the buyer. These guides cover what that actually involves - how purity and identity are measured, how materials degrade, and how to judge a supplier when nobody is checking on your behalf.
How peptide purity is actually testedHPLC tells you how much of something is there. Mass spectrometry tells you what it is. A certificate needs both, and most buyers only check one number.Storing and handling research peptidesLyophilised powder and reconstituted solution have completely different stability profiles. What temperature, light, and freeze-thaw cycles actually do to a peptide.How to vet a peptide supplier'Research use only' means no regulator is checking. That makes the certificate of analysis the only evidence you get, and it is worth knowing what it does and does not prove.
These guides cover laboratory handling and verification of research materials. Nothing here is medical advice.
