Hypothalamic neuropeptide (hypocretin-1) central to wakefulness research.

Also referred to as: Orexin A (Hypocretin-1)

UK supplier comparison

Use the filters to pick a size and presentation (vial, pen or serum) and compare like for like, or view every size on a £ per mg basis. Delivery is shown separately because it varies by supplier and order size. Offers whose outbound link failed our last check stay listed but rank below working links.

Suppliers are being onboarded. This comparison will populate as listings go live. Everything below — the research profile, molecular facts and guides — is available now.

For in-vitro laboratory research only

Orexin A is listed here as a research material. It is not for human or veterinary consumption, and nothing on this page is medical advice or dosing guidance. PeptideCompare is paid by flat supplier fees — never by sales commission or referral — so a price ranks by its number, not by who pays. We do not sell, test or verify any product, and quality or CoA labels are suppliers’ own claims. Always check the final price, documentation and legality with the supplier yourself.

Research profile

About Orexin A in the lab

Orexin A is a 33-amino-acid peptide with two disulphide bridges, made by neurons in the lateral hypothalamus. Loss of these neurons underlies narcolepsy type 1, and orexin signalling is a major topic in sleep, arousal and feeding research.

Proposed mechanism

Activates both orexin receptors (OX1R and OX2R), excitatory GPCRs that drive monoaminergic and cholinergic arousal centres.

Typical research themes

  • OX1R/OX2R pharmacology
  • Sleep–wake regulation
  • Arousal circuits

This profile is a short, general summary of publicly discussed science. It is not exhaustive, not peer-reviewed by PeptideCompare, and is not medical advice. PeptideCompare provides no dosing, protocol or usage guidance — nothing here is for human or veterinary use.
