PeptideBase reports these lab-published figures and does not itself test, endorse, or certify any product. Verified results come from an independent lab-database lookup; vendor-published results are reported by the vendor and are not independently verified. “Peptides lab-tested” counts this vendor’s COAs on file, not a share of their catalog.
PeptideBase provides educational research tools and provider discovery. It does not provide medical advice, diagnosis, treatment, prescribing guidance, or dosing instructions. Consult a qualified healthcare professional before making health decisions.
