Information for institutional quotation
Epitalon: price, documentation and dispatch in Colombia
Epitalon is listed in this catalog as a peptide reference intended exclusively for research and laboratory work, classified as a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. That four-amino-acid sequence is the structural classification the catalog declares, within the immunomodulation, longevity, and cellular metabolism category, one of the catalog's largest thematic groupings. This page brings together the available presentation, the current price shown in the commercial block, and the documentary conditions for an institutional quote. The identity and purity of the lot are not inferred from the declared sequence; they are confirmed by the certificate of analysis Janoshik Analytical issues per lot, using HPLC for purity and mass spectrometry for identity. This page explains how to place Epitalon within its category, alongside other references that share that same commercial classification but belong to different structural classes. The verified classification the catalog assigns to this reference is synthetic tetrapeptide Ala-Glu-Asp-Gly.

Four amino acids, one declared sequence
The catalog classifies Epitalon as a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly, meaning four amino acids — alanine, glutamic acid, aspartic acid, and glycine — joined in that order. This is the most precise structural classification the catalog declares for this reference, and it matches the standard naming used to identify the compound in the technical literature. This page does not translate that sequence into a biological effect or an expected outcome; it is limited to documenting what type of molecule this is.
A four-amino-acid tetrapeptide is a considerably shorter chain than other references in the same category, such as LL37, which the catalog declares at 37 amino acids. That length difference is a verifiable structural data point, useful for an institution comparing several research references to understand that not every peptide chain in this category has the same size or the same declared origin.
Where it sits within the cellular longevity category
Epitalon is grouped in the immunomodulation, longevity, and cellular metabolism category, the same one that includes, among other references, LL37, NAD+, SS-31, and Vesugen. Each of those references has a distinct structural classification: a 37-amino-acid peptide, a non-peptide coenzyme, a tetrapeptide with a declared affinity for a membrane lipid, and a tripeptide from the peptide bioregulator family. Epitalon adds to that group the classification of a short, fully defined synthetic tetrapeptide.
This category membership is commercial and thematic, not a claim that all these references share a mechanism or composition. Each keeps its own technical page, its own presentation, and its own lot certificate. The category simply groups references the catalog associates with a shared field of research interest, without equating their molecular classification.
A single presentation: what it determines on this page
Epitalon is offered in a single 50 mg presentation, measured by mass, which corresponds to a lyophilized powder in a vial under the criterion the catalog applies. With no milligram variants, the institutional request is simplified to a single reference code, without the need to distinguish between presentations as with other catalog entries offering two or more options.
The current price for that presentation is shown in the commercial block of this page and should be confirmed in writing during the institutional quote. Since there is only one presentation, it helps for the request, the quote, and the payment receipt to repeat the same reference code and the same declared 50 mg, so a later review does not have to infer which product the payment corresponds to.
What Janoshik's COA confirms for a short tetrapeptide
Epitalon's certificate of analysis is issued by Janoshik Analytical, per lot, using HPLC for purity and mass spectrometry for identity. For a short-chain tetrapeptide, mass spectrometry is particularly relevant to confirm that the Ala-Glu-Asp-Gly sequence matches the material dispatched, while HPLC documents the purity of the specific lot. The COA is arranged on request and subject to documentary availability.
This page does not publish a purity percentage, a CAS number, a molecular formula, or a molecular weight for Epitalon, because that data is not verified in the documentation available for this page, beyond the four-amino-acid sequence the catalog does declare. Any additional figure should be requested and checked against the certificate for the lot received, not filled in simply because it is a short, seemingly simple peptide.
Storing a short-chain synthetic peptide
Epitalon's storage conditions are set by the documentation applicable to the lot. If that documentation specifies a 2-8 °C range and protection from light, the receiving institution should build that condition into its custody record. A short-chain peptide like this one is not exempt from that documentary control because of its small size: the storage condition depends on the lot and its accompanying documentation, not on the length of the sequence.
Epitalon is handled on a made-to-order basis, with a 15-day coordination window. Shipping fees for Bogota and other domestic destinations are set out on the site's shipping information page and are confirmed along with the delivery date 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.
Quoting and comparing with other references in the same category
An Epitalon order is recorded first, the quote is confirmed in writing, and payment is coordinated afterward, with the method and total already set. Before approving the spend, the institution can compare this reference with others in the same immunomodulation and longevity category, keeping in mind that they share a commercial grouping but not a structural classification, presentation, or lot certificate.
The recommended purchase file brings together the request, the confirmed quote, proof of payment, dispatch confirmation, the receiving record, and Janoshik's certificate for the lot when one was requested. This page stays within the research and laboratory framework the catalog declares, without attributing to Epitalon any function beyond its verified structural classification.
Frequently asked questions about Epitalon
What amino acid sequence does Epitalon have?
The catalog classifies it as a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly: alanine, glutamic acid, aspartic acid, and glycine, in that order. This is the declared structural classification, not an analytical figure from a specific lot.
How does Epitalon differ from SS-31 and Vesugen, in the same category?
Epitalon is a tetrapeptide with the sequence Ala-Glu-Asp-Gly. SS-31 is a tetrapeptide with a declared affinity for cardiolipin. Vesugen is a tripeptide from the peptide bioregulator family. They share a commercial category, not a structural classification.
Who certifies Epitalon's lot?
Janoshik Analytical, per lot, using HPLC for purity and mass spectrometry for identity. The certificate is arranged on request and subject to documentary availability.
How is Epitalon stored?
Per the documentation applicable to the lot. If it specifies 2-8 °C and protection from light, that condition should be built into the laboratory's custody setup before receiving the package.
Does Epitalon ship immediately?
No. It is handled on a made-to-order basis, with a 15-day coordination window, unlike other catalog references such as Glutathione or NAD+, which are listed with immediate delivery.
