Information for institutional quotation
SS-31: price, documentation and dispatch in Colombia
SS-31 is listed in this catalog as a peptide reference intended exclusively for research and laboratory work, classified as a tetrapeptide with a declared affinity for cardiolipin, a lipid specific to mitochondrial membranes. Within the immunomodulation, longevity, and cellular metabolism category — one of the catalog's largest groupings — it shares with Epitalon the short-chain tetrapeptide classification, although the two are distinguished by the declared structural affinity. 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 assumed from the declared structural affinity; 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 what that declared affinity means and how SS-31 is positioned relative to another mitochondrial reference in the catalog. The catalog's verified molecular descriptor is tetrapeptide with cardiolipin affinity.

A tetrapeptide directed at a membrane lipid
The catalog classifies SS-31 as a tetrapeptide, meaning a chain of four amino acids, with a declared affinity for cardiolipin. Unlike a peptide described solely by its sequence, such as Epitalon, SS-31's classification also includes a reference to the molecule with which that structural affinity is declared. This page documents that declared relationship without describing what results from that affinity in an organism.
This classification approach, combining chain length and declared affinity for another molecule, differs from Epitalon's, which is identified solely by its Ala-Glu-Asp-Gly sequence, and from Vesugen's, which is identified by belonging to a peptide bioregulator family. All three are short chains in the same commercial category, but each is classified by a different structural criterion.
Cardiolipin: what this declared structural affinity means
Cardiolipin is a lipid present in mitochondrial membranes, and the catalog declares that SS-31 has an affinity for that molecule. This structural fact is limited to the declared relationship between the peptide and that specific lipid, without describing a function, an outcome, or an effect in the mitochondria or the organism. This page documents the classification, not a biological consequence of that affinity.
The catalog has another mitochondria-related reference through a different route: MOTS-c, a 16-amino-acid peptide the catalog describes as encoded in mitochondrial DNA. The difference between the two is clear: SS-31 is a synthetic tetrapeptide with a declared affinity for a mitochondrial-membrane component, while MOTS-c is a peptide with a declared genetic origin, encoded within the mitochondria's own DNA.
The declared 50mg and its powder physical form
SS-31 is offered in a single presentation of 50 mg, measured by mass, which corresponds to a lyophilized powder in a vial under the criterion the catalog applies. The current price for this presentation is shown in the commercial block of this page and should be confirmed in writing during the institutional quote, without assuming it matches another reference in the same category.
The current commercial value the catalog declares for SS-31 is not tied to chain length, which is the same as Epitalon's, but to this reference's own price listing. Before approving a quote, the purchasing institution should confirm that price in the page's commercial block, since that is the current source, not a value to infer from this page.
Janoshik's COA and the limits of what it certifies
SS-31's certificate of analysis is issued by Janoshik Analytical, per lot, using HPLC for purity and mass spectrometry for identity. The COA confirms identity and purity of the dispatched material; it does not confirm or document the declared cardiolipin affinity, which is a structural classification from the catalog and not a result measured in a lot certificate. The COA is arranged on request and subject to documentary availability.
This page deliberately leaves blank the purity percentage, the CAS number, the molecular formula, and the molecular weight for SS-31: those are figures the available documentation does not verify, and a blank field is more honest than a guessed one. The COA is provided on request and subject to documentary availability, always referring to the lot dispatched.
Storage within the range declared by the catalog
For custody, the document traveling with the lot governs. If it states a 2-8 °C range with protection from light, the institution should have the space assigned before the 50 mg vial arrives, and record it in its internal log.
SS-31 is handled on a made-to-order basis, with a 15-day coordination window. Shipping fees to Bogota and to the rest of the country are set out on the site's shipping information page; the exact date is confirmed during the quote, which is also where the total is closed out. 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.
Traceability of an SS-31 purchase: from order to lot certificate
Since this is a single presentation, the institutional request should repeat the full name, the code, and the declared 50 mg in the quote, the payment receipt, and the receiving record, so the purchase file allows unambiguous reconstruction of which reference and which lot were acquired, together with Janoshik's certificate when one was requested.
The purchase moves in three stages — request, written quote, payment — and never in reverse. What remains should allow reconstruction: request, quote, proof of payment, dispatch confirmation, the receiving record, and Janoshik's lot certificate if one was requested.
Frequently asked questions about SS-31
What does it mean that SS-31 has an affinity for cardiolipin?
It is a structural classification declared by the catalog: cardiolipin is a lipid found in mitochondrial membranes to which SS-31 is declared affine. This page does not describe a function or an effect derived from that affinity.
How does SS-31 differ from MOTS-c?
Both relate to the mitochondria, but through different routes: SS-31 is a tetrapeptide with a declared affinity for cardiolipin, and MOTS-c is a 16-amino-acid peptide encoded in mitochondrial DNA.
Does SS-31 have more than one presentation?
No. The catalog offers it in a single presentation of 50 mg, measured by mass, corresponding to a lyophilized powder in a vial. The institutional request is reduced to a single reference code.
Who certifies SS-31's lot?
Janoshik Analytical, per lot, using HPLC for purity and mass spectrometry for identity. The certificate confirms identity and purity, not the structural affinity the catalog declares.
How is SS-31 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.
