Thymosin Alpha-1: price, documentation and dispatch in Colombia
Thymosin Alpha-1 comes in a single version, 5 mg vial, from US$79, classified as a 28-amino-acid acetylated peptide derived from prothymosin alpha. Within the immunomodulation, longevity, and cellular metabolism category, it shares space with ARA 290 (Cibinetide) and RA260, and carries a naming relationship — though not a structural one — to Thymalin, another catalog reference associated with the thymus. This page organizes identification, presentation, and price, and how each lot is confirmed through the Janoshik Analytical certificate, strictly within the framework of research and laboratory work.

A defined 28-amino-acid molecule, originating from prothymosin alpha
The published classification describes Thymosin Alpha-1 as a 28-amino-acid acetylated peptide derived from prothymosin alpha. It is a relatively long chain for the catalog, more than double the length of a secretagogue hexapeptide like GHRP-2 or Hexarelin, and with a specific declared modification: acetylation, which the certificate's mass spectrometry can distinguish from the non-acetylated form of the same sequence.
The origin in prothymosin alpha is a structural derivation fact, the same as ARA 290's relationship to erythropoietin or P21's relationship to ciliary neurotrophic factor. In all three cases, this page documents which protein or factor each peptide derives from, without translating that relationship into any claim about its use.
A single 5 mg presentation: what to state in the quote
The catalog offers Thymosin Alpha-1 in a single presentation, 5 mg vial, with a current listed price from US$79. Anyone quoting this reference checks that figure in its own commercial block, without assuming it matches another catalog reference with a similar name, such as Thymalin.
The institutional quote must confirm this value at the time of the request, since the catalog can update prices without that change being reflected in a fixed text like this one.
Certificate of analysis per lot: Janoshik Analytical, HPLC, and MS
The classification as a 28-amino-acid acetylated peptide does not replace the documentary verification of each specific Thymosin Alpha-1 lot. That verification is the role of the certificate of analysis (COA) that Janoshik Analytical issues per lot: high-performance liquid chromatography (HPLC) for purity and mass spectrometry (MS) for identity.
The COA is handled on request and subject to documentary availability. This page does not publish a purity figure for Thymosin Alpha-1, nor a CAS number, nor a molecular weight: if those data are not in the delivered lot's document, they remain pending, not filled in by comparison with Thymalin or with any other reference related by name.
Physical form and storage of the 5 mg vial
As a specification declared in milligrams, the 5 mg Thymosin Alpha-1 vial corresponds to lyophilized powder. Storage is governed by the documentation applicable to the lot: when that documentation states a 2–8 °C range with protection from light, the receiving institution should have the custody space assigned before the material arrives.
On receipt, the full reference name, the 5 mg presentation, and the lot visible on the vial should be checked against the accepted quote, without confusing it by name with Thymalin, a separate reference in the general catalog.
From the institutional quote to payment
Selecting Thymosin Alpha-1 in the catalog does not generate an immediate charge. The request is recorded first with the 5 mg presentation and the current price; the commercial confirmation that follows fixes the total, the destination, and the payment method in writing. Shipping is calculated separately, with rates for Bogotá and for the rest of the country shown on the site's shipping information. 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.
Before authorizing payment, it is worth checking that the quote received states the full reference name, the 5 mg presentation, the unit price, the shipping cost, and, if requested, the status of the COA.
Thymosin Alpha-1 versus Thymalin: a defined molecule against a complex
Thymosin Alpha-1 and Thymalin share a name root associated with the thymus, but their structural classification is different: Thymosin Alpha-1 is a single, defined molecule, a 28-amino-acid acetylated peptide derived from prothymosin alpha, while Thymalin is described in the general catalog as a complex of low-molecular-weight peptides obtained from the thymus, that is, a mixture of several components rather than a single sequence.
That difference — a single molecule versus a complex of several peptides — is the structural comparison this page can document between the two references, without extending it to any conclusion about their use. ARA 290 and RA260 round out the immunomodulation category with their own structural relationships, one declared and the other not.
Frequently asked questions about Thymosin Alpha-1
What presentation and price does Thymosin Alpha-1 have?
5 mg vial, with a current listed price from US$79. It is the only presentation registered for this reference.
Is Thymosin Alpha-1 the same as Thymalin?
No. Thymosin Alpha-1 is a single molecule, a 28-amino-acid acetylated peptide derived from prothymosin alpha. Thymalin is a complex of several low-molecular-weight peptides obtained from the thymus. They share a name associated with the thymus, not a structure.
How is the purity of a Thymosin Alpha-1 lot confirmed?
With the certificate of analysis (COA) from Janoshik Analytical: HPLC for purity and mass spectrometry for identity, per lot, on request and subject to documentary availability.
What protein does Thymosin Alpha-1 derive from?
From prothymosin alpha. It is a 28-amino-acid acetylated peptide derived from that reference protein, according to the published structural classification in the catalog.
How much does shipping cost for an order with Thymosin Alpha-1?
Rates for Bogotá and for the rest of the country are shown on the site's shipping information, with delivery time confirmed during the institutional quote. 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.
