Overview
About Orexin A.
Orexin A (hypocretin-1) is an endogenous 33-residue neuropeptide that acts as an agonist at both orexin receptors, OX1R and OX2R. Through this receptor signaling it is studied for its role in the regulation of wakefulness, arousal, and appetite in research models.

FAQ
Orexin A — frequently asked by B2B buyers.
What format and vial sizes is Orexin A supplied in?
Pepti supplies Orexin A as a research-use lyophilized (freeze-dried) powder in 10 mg and 20 mg vials. Custom fill sizes and bulk quantities can be quoted on RFQ.
What documentation ships with each lot?
Every lot ships with a Certificate of Analysis showing HPLC purity and mass-spectrometry (MS) identity confirmation. Additional lot documentation and specifications are available on request for B2B and private-label buyers.
What is the minimum order quantity, and can you private-label?
Standard MOQ is 50 kits (500 vials). As an OEM/private-label supplier, Pepti can provide custom labeling, packaging, and documentation for brand buyers; details are arranged under RFQ.
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 therapeutic use?
No. Orexin A is supplied strictly for laboratory research and manufacturing use, not for consumer or veterinary consumption or applied use. Buyers are responsible for compliance with applicable regulations in their jurisdiction.
