Quick answer: Cartalax is a synthetic tripeptide made of alanine, glutamic acid, and aspartic acid (Ala-Glu-Asp, or AED). It belongs to the Khavinson family of short-peptide bioregulators and is studied in laboratory models of gene expression and cellular aging. It is a research compound, not an approved medicine.

What Is Cartalax?

Cartalax is a short peptide with three amino acids in a fixed order: Ala-Glu-Asp. Researchers developed it as the cartilage-linked member of a group of small peptides, each matched to a particular tissue. Scientists use it as a reference compound in cell-culture studies.

Cartalax at a Glance

Names: Cartalax, AED, T-31
Sequence: Ala-Glu-Asp
Type: Synthetic tripeptide
Approximate molecular weight: 333.3 g/mol (calculated)
PubChem CID: 87815447
Family: Khavinson short-peptide bioregulators
Status: Research compound, not FDA approved

Where Does Cartalax Come From?

Vladimir Khavinson and his colleagues in Russia developed Cartalax within a program on short peptide bioregulators. The program’s core idea is that very short peptides can influence gene expression in specific tissues. Related members of the family include Vilon, Vesugen, Pinealon, and Livagen.

Researchers still debate this idea, and independent replication of the original work is limited. Treat it as an active research hypothesis.

Why Do So Many Products Share the Name Cartalax?

The name covers more than one kind of product, and that causes confusion. Here is how to tell them apart.

Pure AED peptide: A lyophilized powder containing the defined Ala-Glu-Asp sequence, sold for research
Mixed peptide capsules: Products that contain a broader cartilage-derived peptide complex, often sold as supplements in some regions
Brand-name variations: Listings that use “Cartalax” loosely without stating a sequence

Always look for the full sequence and a batch-matched certificate of analysis. A listing that gives neither is hard to trust.

A Timeline of Selected Cartalax Research

The published work sits mainly in cell cultures and animal tissue. These papers appear in the reference list on the Cartalax entry on Wikipedia.

2015: A study on peptide regulation of cell renewal in kidney tissue cultures from young and old animals
2016: A review titled “Short Peptides Regulate Gene Expression”
2020: A paper on gene expression in aging human mesenchymal stem cell cultures and how short peptides modulate it
Undated entries: A study on peptide regulation of skin fibroblast functions during aging in vitro

Please read the original papers before citing them, since this list gives only titles and topics.

How Does Cartalax Compare With Other Bioregulators?

Each member of the family has its own sequence and research focus.

Cartalax (AED): Tripeptide linked to cartilage-related research
Vesugen (KED): Tripeptide linked to vascular research
Pinealon (EDR): Tripeptide linked to neuronal cell research
Vilon (KE): Dipeptide linked to immune-cell research
Epitalon (AEDG): Tetrapeptide linked to pineal research

The letters look alike, so mix-ups are common. Check the full sequence on every product page and COA.

Frequently Asked Questions About Cartalax

What is Cartalax? Cartalax is a synthetic tripeptide with the sequence Ala-Glu-Asp (AED). Researchers study it in cell models of gene expression and aging.

What does Cartalax stand for? The name is a brand name for the AED peptide. The “cart” part reflects its link to cartilage-related research.

Is Cartalax the same as T-31? Yes. T-31 is another name for the same AED tripeptide.

Is Cartalax FDA approved? No. It is a research compound, and no regulator has approved it for any use.

Is Cartalax a supplement? In research settings, no. Some regions sell products under the same name as supplements, and those are often mixed-peptide products.
