What purity is Orexin A tested to?
Purity is verified per lot by HPLC, with peptide identity confirmed by mass spectrometry. The exact purity value for a given batch is stated on that lot's Certificate of Analysis rather than assumed in advance.
Is Orexin A intended for human use?
No. Orexin A is supplied strictly for laboratory research and manufacturing use, not for human or veterinary consumption or clinical use. Buyers are responsible for compliance with applicable regulations in their jurisdiction.
