Information for institutional quotation
Orexin A: price, documentation and dispatch in Colombia
Orexin A is presented in the Péptidos Colombia catalog as a peptide reference exclusively for research and laboratory work. The catalog describes it as a 33-amino-acid neuropeptide, also called hypocretin-1, and places it within the nootropic and neuromodulator peptides category, where it sits alongside its own related variant, Orexin B. This listing precisely identifies the reference, distinguishes it from Orexin B, describes its presentation within the catalog, and organizes the purchase documentation: certificate of analysis, storage, shipping, and payment. Identity and purity of the lot are confirmed through the certificate issued by Janoshik Analytical, with HPLC for purity and MS for identity, on request and subject to document availability.

Orexin A: a 33-amino-acid neuropeptide, also hypocretin-1
The catalog describes Orexin A as a 33-amino-acid neuropeptide, also called hypocretin-1. This is a structural classification with a dual name: Orexin A is the trade name the catalog uses, and hypocretin-1 is the alternate designation under which it also appears in the technical literature. Both names refer to the same reference.
This listing is limited to that origin classification and does not describe any mechanism associated with the neuropeptide. The exact identity of the shipped lot — whether it does correspond to this 33-amino-acid sequence — is confirmed with the corresponding certificate of analysis, not with the catalog's general description.
Orexin A versus Orexin B: two hypocretins, two distinct references
Orexin A and Orexin B are two distinct references in the same catalog, not two presentations of the same molecule. Orexin A is a 33-amino-acid neuropeptide (hypocretin-1); Orexin B is a linear 28-amino-acid neuropeptide (hypocretin-2). They share the neuropeptide family and the same dual-naming convention, but they are different sequences, with their own presentation, price, and reference code.
When requesting a quote, it is essential to specify which of the two is needed: Orexin A comes in a 10 mg presentation, while Orexin B comes in 5 mg. Writing only "Orexin" without the final letter leaves the request ambiguous between two references that are not interchangeable.
Orexin A and Orexin B, two references in a category of nine
Nootropic and neuromodulator peptides groups nine catalog references: Cerebrolysin, DSIP, Orexin A, Orexin B, P21 (P021), PE-22-28, Pinealon, Selank, and Semax. Within that group, Orexin A and Orexin B are the only two hypocretins: they share the neuropeptide family and the same dual-naming convention, but are presented in different milligram strengths — 10 mg and 5 mg respectively — and each keeps its own reference code.
Current figures for each presentation are shown in the commercial block of this same page, sourced from the catalog, and should be confirmed there, without assuming they match a remembered value from a previous quote. The certificate of analysis and storage conditions follow the same standard for all nine references in the group, regardless of each one's milligram strength.
A 10 mg presentation and physical form
Orexin A is offered in a single presentation, a 10 mg vial. Like every catalog specification declared in milligrams, its physical form corresponds to lyophilized powder in a vial, a criterion the site applies consistently to any reference measured by mass.
With no second presentation of Orexin A, the quote is limited to confirming the full name — including the letter A, so it is not confused with Orexin B — and the number of 10 mg vials required.
Janoshik COA per lot and storage
The certificate of analysis for Orexin A is issued by Janoshik Analytical, with HPLC for purity and MS for identity, per lot rather than for the reference in general. Given this reference's list price, carefully checking that the certificate received corresponds to the exact lot shipped carries additional financial weight for the purchasing institution.
Access to the COA is on request and subject to document availability. The storage condition the site declares for the peptide catalog is 2–8 °C, protected from light, applicable when Orexin A's lot documentation confirms it.
Quoting, shipping, and payment
Shipping cost varies by destination and is shown on the site's shipping information page, the same logistical cost as for any other catalog reference, unrelated to the product's list price. Dispatch time is likewise not fixed here: it is confirmed when requesting a quote, together with destination. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.
Payment is arranged after confirming in writing the reference — Orexin A, not Orexin B —, presentation, units, destination, and total. Given this reference's value, it is worth double-checking that confirmation before proceeding to payment.
Frequently asked questions about Orexin A
Is Orexin A offered for research?
Yes, exclusively for research and laboratory work. The listing is limited to identification, documentation, storage, and purchase logistics.
How does it differ from Orexin B?
Orexin A is a 33-amino-acid neuropeptide (hypocretin-1) in a 10 mg presentation. Orexin B is a linear 28-amino-acid neuropeptide (hypocretin-2) in a 5 mg presentation. They are distinct references.
Are Orexin A and Orexin B interchangeable in a quote?
No. They are two distinct catalog references, each with its own code, its own presentation — 10 mg for Orexin A, 5 mg for Orexin B — and its own current price shown in the commercial block of this page.
Where are identity and purity confirmed?
In the certificate of analysis issued by Janoshik Analytical per lot, with HPLC and MS. It is handled on request and subject to document availability.
How much does shipping cost?
Shipping cost varies by destination; see the site's shipping information page for current rates, unrelated to the product's list price. Outside Colombia, this reference ships to 5 countries (Costa Rica, Ecuador, United States, Mexico and Puerto Rico), from US$57; the rate for each country is listed on the site's international shipping page.
What other references share Orexin A's category?
Cerebrolysin, DSIP, Orexin B, P21 (P021), PE-22-28, Pinealon, Selank, and Semax complete the nine references in Nootropic and neuromodulator peptides. Each keeps its own presentation, price, and lot documentation.
