Cartalax
Cartilage tripeptide bioregulator — connective tissue (no validated dose)

Cartalax is a short synthetic peptide bioregulator — the tripeptide Ala-Glu-Asp (AED) — from the Khavinson family of "peptide bioregulators." It has been studied for effects on chondrocyte and stem-cell gene expression related to cartilage and connective tissue.
Cartalax has no clinical-trial-established human dose. The published research is preclinical — cell-culture and gene-expression studies, mostly from Russian laboratories — so every protocol circulating online is community convention extrapolated from lab work and general peptide-handling habits, not a validated regimen.
Dosing Reference
Reconstitution
Add 2 mL bacteriostatic water to the 20 mg vial. Resulting concentration: 10 mg/mL.
| Dose | Syringe Units | mL Volume | Schedule |
|---|---|---|---|
| 0.2 mg | 2 units | 0.02 mL | Daily SubQ (10–20 day course)Lower community range |
| 1 mg | 10 units | 0.1 mL | Daily SubQ (10–20 day course)Mid community range |
| 2 mg | 20 units | 0.2 mL | Daily SubQ (10–20 day course)Upper community range |
Math assumes U-100 insulin syringes (1 mL = 100 units). Verify your syringe matches before use. Round half-units to the nearest visible mark.
Reconstitution
For a 20 mg vial with 2 mL bacteriostatic water, the concentration is 10 mg/mL; a 1 mg dose draws to 10 units (0.1 mL). With 4 mL, the concentration is 5 mg/mL; a 1 mg dose draws to 20 units (0.2 mL). For a 10 mg vial with 2 mL, the concentration is 5 mg/mL.
For a 0.2 mg (200 mcg) dose at 10 mg/mL, that is just 2 units — which is why many community sources dilute further for measurable volumes. Gently swirl — do not shake. Refrigerate at 2–8°C and use within 28 days.
Cycling Protocol
Community sources describe Cartalax the way the older Khavinson bioregulators were used clinically in Russia — as short, repeated low-dose courses (often 10–20 days) rather than continuous daily dosing. The original rationale is that short peptides act as transient signals to gene-expression machinery rather than agents needing steady blood levels (Khavinson & Anisimov, 2009). There is no controlled human data establishing an optimal cycle length, so this is convention, not evidence.
Routes of Administration
Subcutaneous injection is the route community protocols describe. Some bioregulator products are also sold in sublingual/oral-mucosal formats. No published human trial defines a route for Cartalax specifically.
- Sites: Abdomen, thigh, or other areas with adequate subcutaneous fat, rotating sites across courses
- Volume: Small — at 10 mg/mL even a 1 mg dose is only 0.1 mL
- Because the community dose range is low and uncertain, many users dilute generously so small doses are measurable
Stacking Protocols
There is no human trial data on Cartalax stacks. Community sources sometimes pair it with other Khavinson bioregulators or with better-studied repair peptides, on a theoretical "different mechanisms" rationale.
| Stack | Rationale | Notes | | --- | --- | --- | | Cartalax + BPC-157 | Connective-tissue repair via different mechanisms | No data on the combination; community-reported only | | Cartalax + TB-500 | Broader tissue repair pairing | Theoretical; no controlled data |
These reflect community theory, not validated combinations.
Side Effects & Safety
- Limited safety data — there is no published human safety dataset for Cartalax specifically. Community reports describe it as well tolerated at low doses, but that is anecdote, not a safety profile.
- Injection-site reactions — the most commonly mentioned community-reported event (mild redness or irritation), consistent with other subcutaneous peptides.
- Unknown long-term effects — no long-term human exposure data exists.
The short-peptide bioregulator class has a generally benign profile in the preclinical literature, but absence of reported harm in cell-culture work is not the same as demonstrated human safety.
Research Basis
The honest answer: the dose numbers do not come from human trials.
The published evidence is preclinical. The strongest Cartalax-relevant study examined the AED peptide's effect on gene expression in aging human mesenchymal stem cells, where it raised IGF1 gene expression several-fold in cell culture (Ashapkin et al., 2020, PMID 32399807). A 2023 review summarized AED among peptides studied for chondrogenic (cartilage-forming) stem-cell regulation (Linkova et al., 2023, PMID 37176122). Both are cell-culture/mechanistic studies — neither establishes a human dose.
Community doses are extrapolated. The low-dose, short-course pattern is borrowed from how the original Khavinson tissue bioregulators were used, scaled by analogy and general peptide-handling convention. That is a reasonable starting point for the community, but it is not a tested protocol.
