What is Cartalax, and what is it used for?
Supplier lists write it as Cartalax peptides or peptide Cartalax; every one of those is this record, and the lot certificate further down counts for more than the wording on a label.
Chemically: molecular formula C12H19N3O8, average mass 333.29 g/mol (PubChem CID 87815447). Those figures are what the identity test on a certificate is read against.
Short synthetic peptide from the Khavinson "bioregulator" series.
Mechanism is not established in the conventional receptor sense. The originating group proposes that these peptides act epigenetically, entering cells and binding directly to specific DNA sequences to modulate transcription of tissue-relevant genes, with molecular docking used as the supporting method. That is a hypothesis about a mechanism, not a demonstrated pathway, and it has not been independently confirmed outside the groups that advanced it.
Appears in a preclinical literature of organotypic tissue culture, rodent models and gene-expression work, largely produced by the St Petersburg Institute of Bioregulation and Gerontology and collaborating Russian institutes. A substantial share is published in Russian, in journals with limited international circulation.
No approved product outside Russia, no pharmacopeial monograph, no independently replicated mechanism, and no controlled trial meeting United States or European standards. The volume of commercial writing about this series greatly exceeds what its cited sources report.
Cartalax for sale: 20mg vials, price per mg
Cartalax is sold in 1 size here, 20mg, from $85.00 a vial. Cartalax cost and Cartalax price per mg by size are in the table, at each volume tier and on subscription; the per-mg figure under each price is the one that compares across sizes.
Volume and subscription pricing by size
| Size | One vial | 10–19 vials−10% | 20 vials−15% | Subscribe monthly−6% from shipment 2 | Availability |
|---|---|---|---|---|---|
| Cartalax 20mg | $85.00$4.25/mg | $76.50a vial · $3.83/mg | $72.25a vial · $3.61/mg | $79.90a vial, shipment 2 on · $3.99/mg | Backordered — waitlist |
Volume tiers are per size and do not combine across sizes (see bulk pricing). Subscribe & Save takes 6% every month, 4% every 2 months or 2% every 3 months off from shipment 2, two shipments minimum, and stacks on the volume tier: the lowest this record ever bills is $3.40 per mg, twenty 20mg vials on a monthly subscription from shipment 2 onward.
Nothing is added at checkout except the USPS shipping you choose; dispatch and delivery are the same on every order. The cost-per-milligram tool ranks the whole catalog by price per mg.
Where to buy Cartalax: what to check before you order from anyone
Cartalax for sale, or Cartalax peptide for sale, means this page: one record, 1 size. You can buy Cartalax online here with guest checkout; verified in-stock orders placed before 12 PM Pacific are dispatched the same day.
Before ordering Cartalax from anyone, us included, run the 5 checks on verifying a certificate; the first is that the report resolves on the laboratory's own site, and a seller who cannot pass them is asking for the trust a certificate exists to replace.
The Cartalax certificate: lot, purity, identity, and how to verify it
A certificate answers identity, purity and net content as three separate questions, each with the method that produced it and the date it was run, how to read one covers what each field does and does not cover. For Cartalax that means a mass spectrum landing on 333.29 g/mol for C12H19N3O8, the figure published against PubChem CID 87815447. The cataloged form is Ala-Glu-Asp (AED tripeptide), and the identity test resolves to that rather than to a related molecule with a similar name.

Where the FDA stands on Cartalax
FDA status, and what this listing is Not an FDA-approved drug product
The FDA has not approved this compound for anything, and nothing in this catalog is a medicine.
Status verified 2026-08-25. Check the primary source before relying on this summary.
It is sold as laboratory material under the research-use restriction below. Being listed is not an approval, and not a claim that it is safe, effective or right for any purpose.
Cartalax research: what the published studies examine
Status: No FDA-approved application. This compound is sold as laboratory material. Where research on it has been published, it sits at the animal, cell or early-human stage, and this record does not summarize what it found. A supplier is not a neutral judge of evidence about its own catalog.
Cartalax is the cartilage-associated member of the series and is indexed by PubMed under the tripeptide sequence Ala-Glu-Asp. The originating group proposes that these peptides act epigenetically, entering cells and binding directly to specific DNA sequences to modulate transcription of tissue-relevant genes, with molecular docking used as the supporting method. That is a hypothesis about a mechanism, not a demonstrated pathway, and it has not been independently confirmed outside the groups that advanced it.
The series was developed at the St Petersburg Institute of Bioregulation and Gerontology, and the design premise is tissue specificity: each short peptide is claimed to act on the organ its parent extract came from. That premise rests principally on explant-outgrowth assays from the same group.
| Reported observation | Model | Source |

| The originating review sets out the peptide theory of ageing and the design principle behind the series: dipeptides specific for thymus and tetrapeptides specific for heart, liver, brain cortex and pineal gland stimulate outgrowth of explants from their corresponding organs. It reports lifespan extension in rats, mice and fruit flies for the pineal preparations. | review of three decades of the originating group's own work | Khavinson, Peptides and Ageing, Neuroendocrinology Letters (2002)A 134-page supplement authored by the series originator reviewing his own institute's work.

| Synthetic peptides cardiogen, bronchogen, prostamax and pancragen were applied to organotypic explant cultures from heart, lung, prostate and pancreas of young (3-week) and aged (18-month) rats.

Open questions. The indexed literature specific to Cartalax is very thin. Its cartilage association comes from the tissue-extract origin of the series rather than from published work in cartilage, and no study in the indexed record examines it in that tissue. Two limitations apply to every compound in this series and are worth stating plainly rather than once at the bottom of a catalog.
First, provenance: the great majority of primary work comes from one institute and its collaborators, much of it published in Russian, and independent replication outside that network is scarce. That is a limit on how confidently the findings can be read, not an allegation about them. Second, the assays: explant outgrowth in organotypic culture and gene-expression shifts in cultured cells are the dominant endpoints, and neither establishes what a compound does in an intact animal, let alone a person.
The proposed epigenetic mechanism — short peptides entering the nucleus and binding DNA directly — is supported largely by molecular docking, which is a computational prediction rather than a measurement.
Each row above describes an observation in the stated model. None of it describes what Cartalax would do in a person or an animal outside that model, and none of it is a recommendation to use it for anything.
How to store Cartalax: refrigeration and shelf life
Keep the sealed vial cold and out of the light and it stays as it left the lab. Once it is mixed into a solution, how long it holds up depends on the compound, what it was mixed with, how strong the solution is and how cold it is kept — too many variables for anyone to print one shelf life on a label. So laboratories write the date on whatever they prepare and keep their own record of it.
For solution preparation arithmetic on the bench, concentration, per-graduation values and molarity, use the vial concentration calculator, which opens with the Cartalax sizes stocked here already loaded. It covers laboratory measurement only and contains no administration guidance.
