Cartalax
Cartalax (Khavinson)
Cartalax (Ala-Glu-Asp) is a Khavinson bioregulator tripeptide targeting cartilage and musculoskeletal tissue gene expression. It supports chondrocyte function, cartilage matrix synthesis, and joint tissue maintenance. Developed for age-related cartilage decline and osteoarthritis support.
Starting dose. 2 mg — Daily
SubQ injection, any time of day. 10-20 day courses, 2-3 cycles per year with 4-6 months between courses (Khavinson protocol). Pin alone or with other bioregulators only.
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
How it works
Cartalax penetrates chondrocytes and modulates expression of genes involved in proteoglycan synthesis, collagen type II production, and cartilage matrix maintenance. Supports the balance between matrix synthesis and degradation (MMP regulation) in articular cartilage.
What to expect
Days 1-10: Gene changes initiated.
Weeks 2-8: Cartilage gene programs established.
Months: Sustained cartilage support.
Evidence
Claims we could not support
No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.
Dose/route: 2 mg SubQ daily for a 10-20 day course. No checked abstract administered Cartalax subcutaneously at this dose or course length.
Mechanism: proteoglycan synthesis, collagen II production, and MMP regulation in articular cartilage. The exact AED/Kartalax abstracts found addressed chondrocyte senescence-associated secretory markers, not the page’s proteoglycan, collagen-II, or MMP mechanism.
Primary safety concern / no significant adverse events at the displayed regimen. No checked human SubQ safety abstract for Cartalax was found.
The honest take
Cartilage regeneration support
Bioregulatory mechanism targets cartilage-specific gene expression. Complementary to direct repair peptides.
Interactions & stacking
Two different questions: what is documented about running these together, and what is documented about drawing them into the same syringe. A good pharmacological partner can still have to be pinned separately.
Documented together
Keep separate
Check any specific pair in the Stack & Interaction Checker, which answers both questions separately. Absence of a documented conflict is not evidence of safety.
Side effects & safety
Commonly reported
- Very well tolerated
- Mild injection site irritation
Less common & notes
- Excellent safety profile.
- No significant adverse events reported.
Pharmacokinetics
SubQ
Weeks to months (cartilage gene expression changes persist long after peptide clearance)
Rapid enzymatic degradation (peptidases); renal excretion of amino acid components
Storage. Standard BAC water 2-8C. 21-28 days.
Regulatory status
Not FDA-approved. Research peptide.

Calculate, log & track
Open Cartalax straight into OnePin with your vial and dose pre-filled, then let it handle the syringe math and remind you before the vial runs out.
