Cartalax Dosage, half-life & reference guide

Also known as AED peptide · Ala-Glu-Asp · Kartalax

A short peptide from the Russian bioregulator program behind Epitalon and Pinealon, which its developers describe as a bioregulator for cartilage and joints. In cell studies it raised the genes cartilage is built from in aging stem cells and damped the aging signals of cartilage cells, and in rats it slowed bone loss. No human study has been published, and nearly all the research is by its developers.

How it works.

A tripeptide, Ala-Glu-Asp (AED), from the Russian bioregulator program of Vladimir Khavinson's St. Petersburg Institute of Bioregulation and Gerontology, the group behind Epitalon and Pinealon. Its developers found it in their peptide extract of animal cartilage and describe it as the bioregulator of cartilage and the musculoskeletal system: in their scheme each short peptide regulates one tissue, by binding DNA and changing which genes are read. In aging human stem cells grown in the lab it raised the genes and proteins cartilage is built from (SOX9, aggrecan, type II collagen) and in chondrocyte cultures it damped the signals of cell aging; in rats with induced bone loss it kept bone density from falling. No human study of Cartalax has been published, and almost all of its research comes from its developers.

Commonly reported: Easier, less stiff joints over a few weeks for some, quick relief for a few and nothing at all for others; it is often added to BPC-157 and TB-500 or the KLOW blend.

  1. Day 1–7Community

    Most feel little in week one

    Commonly reported: little to feel in the first days, with a few describing quick relief in a sore joint. A line each morning on how your joints feel gives you an honest read to compare against later.

    Updated Oct 2026

  2. Day 7–21Community

    Joints start to feel easier

    Commonly reported: a gradual easing of stiffness and better day-to-day comfort over the second and third weeks, for some. Others notice nothing at all, the most common letdown in user reports.

    The science

    No study has measured how fast anything changes in people. In aging human stem cells grown in the lab, AED raised the genes and proteins cartilage is built from: SOX9, aggrecan, type II collagen and COMP (Myakisheva 2023).

  3. Day 21–60Community

    Time for an honest look

    A typical course ends around here: its developers' capsules are labelled for a month, and injected courses commonly run 10–20 days. Compare against how your joints felt on day one; the next course usually waits months.

    The science

    No study has tested a course length or what lasts after one. In chondrocyte cultures, AED brought the aging signals that build up in osteoarthritis (p16, p21, p53, TNF-α and IL-1α) back toward normal and restored SIRT1 (Myakisheva 2023).

    What Cartalax is built on

    A tripeptide from the same Russian bioregulator program as Epitalon and Pinealon, which its developers describe as cartilage's own regulator. Its evidence is cell studies and one rat study, almost all by its developers and much of it in Russian journals; no human study has been published.

    The science

    AED is one of the short peptides its developers identified in their cartilage extract (Linkova 2023). In aging human stem cells it raised SOX9, aggrecan, type II collagen and COMP (Myakisheva 2023); in rat skin cells aging in culture it lowered MMP-9, an enzyme that breaks down tissue, and cut programmed cell death (Lin'kova 2016). In rats after ovary removal it kept bone density from falling, less well than the cartilage extract (Povorozniuk 2007). The developers' claims of use in people with osteoarthritis rest on their 2008 patent and their own reviews; no such study is indexed in PubMed, and no trial is registered on ClinicalTrials.gov.

  5. With BPC-157 and TB-500Community

    The cartilage piece of a healing stack

    Commonly reported: Cartalax is added to BPC-157 and TB-500, or the KLOW blend, when a joint or an old injury is the target, as the piece aimed at cartilage. No study has tested it with either.

    The science

    BPC-157's and TB-500's cases are animal work on blood supply and repair cells (see their entries); the one controlled test of the two together, in rats with repaired Achilles tendons, found the pair added nothing over either alone (Biçer 2026). Cartalax's case is cell work on cartilage-building genes (Myakisheva 2023). Nothing has combined Cartalax with either.

Day 1 is the day you start it.

No human study of Cartalax has been published. Timelines are what users commonly report; the mechanism comes from cell studies and one rat study, almost all by its developers.

Preliminary research

A typical run.

Run notes

Cycle
Run in courses rather than continuously, like the other bioregulators. Its developers' capsules are labelled for a one-month course, repeated after 3–6 months; injected courses commonly run 10–20 days, a few times a year, and some run for weeks longer. No study has tested a course length.Community practice — opinions vary. Not a clinical recommendation.
Timing
No timing has been studied. Its developers' capsules are taken with meals.
Routes
SubQ injection, Oral capsules
Stacks
BPC-157, TB-500

Safety.

Common side effects

  • Injection-site redness or itch
  • Stinging on injection
  • Mild fatigue early in a course
  • Light headache

Interactions

No interaction studies exist, including with BPC-157 and TB-500, the peptides it is most often stacked with.

Safety notes

No safety study exists: no human trial of Cartalax has been published, so its side effects are known only from user reports, and nothing is known about long-term use. Discuss with your clinician before use, particularly during pregnancy or breastfeeding.
