Cartalax
A Russian 'bioregulator' tripeptide aimed at cartilage — with very limited evidence.
Overview
Cartalax is a three-amino-acid peptide (alanine-glutamic acid-aspartic acid) from the short-peptide 'bioregulator' program of Vladimir Khavinson in St Petersburg. It is promoted for cartilage, joint and connective-tissue aging. Almost all research comes from that group, mainly in cell cultures and animals, published largely in Russian journals.
How it works
Proposed to enter cells and interact with DNA and chromatin, adjusting gene activity in cartilage and connective-tissue cells. In cell studies it is reported to influence markers of cell aging and repair. This 'gene-regulating short peptide' model has not been independently confirmed.
Evidence
1/5
Mostly in-vitro and animal work from one research group. No independent controlled human trials.

Reported benefits
Cartilage cell activity
Reported to support cartilage and connective-tissue cell function in cell cultures.
Markers of cell aging
Reported to shift aging-related markers in cultured cells.
Joint comfort
Some users report less joint stiffness; no controlled data.
“Anecdotal” means reported by users, not shown in controlled trials.

Math only: concentration (mg/mL) = vial mg ÷ mL of water; units = dose (mg) ÷ concentration × 100. Always double-check against your own vial label and a clinician. This tool does not recommend a dose.
Reconstitution
Diluent: Bacteriostatic water (0.9% benzyl alcohol) — allows multiple draws from one vial.
- Wipe both vial tops with an alcohol swab and let dry.
- Draw the diluent, then inject it slowly down the inside wall of the vial — never straight onto the powder.
- Swirl gently or let it sit; do not shake. Foam can damage peptides.
- Solution should be clear. Cloudy, stringy or discolored = discard.
- Common mix: 20 mg + 2 mL = 10 mg/mL (1 mg = 10 units).
Storage
Powder
Freezer / fridge
Keep sealed vial in the freezer (−20 °C) for long-term storage; fridge (2–8 °C) is fine for a few weeks. Keep dry and out of light.
After mixing
~28 days
Refrigerate at 2–8 °C. Never freeze after mixing. Keep upright, capped, and out of light.
Travel
Keep cool
Short trips at room temperature are generally fine for powder; keep mixed vials cold.
Side effects & cautions
Reported side effects
- Injection-site redness
- Mild headache or fatigue (user reports)
- Unknown long-term effects
Cautions
- Evidence comes almost entirely from one research group and has not been independently replicated.
- No human safety data to speak of.
- No data in pregnancy or breastfeeding.
FDA & international status
Not FDA-approved
Cartalax is not an approved drug in the US. It is sold as a research chemical.
Regulations change often — verify with the FDA, EMA, MHRA, Health Canada, TGA and WADA before acting.
Often paired with
EpithalonBoth are Khavinson bioregulators and share the AED motif; they are often run together in 'bioregulator' courses.

FAQ
What is a 'peptide bioregulator'?
A term from Russian research for very short peptides said to restore normal gene activity in specific tissues. The idea is interesting but not well supported outside that research group.
Is it related to Epithalon?
Yes. Cartalax is AED; Epithalon is AEDG — the same three amino acids plus glycine.
Will it fix arthritis?
There's no human trial showing that. Treat claims about cartilage repair as unproven.
