Compound classes
Most research catalogues group peptides by mechanism: GLP-1 / metabolic, growth-hormone axis, regenerative, immune, cognitive, performance / longevity, and cosmetic / hormone. Regena's catalogue follows the same structure.
What every batch should publish
HPLC purity (with the test report), mass-spec identity confirmation, peptide content, water content and a lot-matched COA. Anything missing is a red flag.
How researchers compare suppliers
Independent COAs, batch consistency over time, cold-chain handling and responsiveness on technical questions. Price-per-mg matters, but only after documentation passes.
