What Is Cartalax? Dosage, Half-Life & How to Track It
Also known as: Ala-Glu-Asp · AED Peptide · Khavinson Bioregulator
Cartalax is a synthetic tripeptide — Ala-Glu-Asp — from Vladimir Khavinson’s bioregulator research, studied for effects on cartilage and connective-tissue cells. Protocols titrate from 2 mg up to 5 mg subcutaneously once daily over roughly 12 weeks. Published human dosing data is limited; this framework is extrapolated from preclinical research, and this page is educational only.
What Cartalax is and how it works
Cartalax belongs to the same Khavinson bioregulator family as Pinealon and Chonluten — a short, tissue-targeted tripeptide, in this case Ala-Glu-Asp, studied for effects on cartilage and extracellular matrix (ECM) biology. Preclinical work looks at markers like Ki-67 (a proliferation marker) in fibroblasts and chondrocytes, alongside reduced activity of pro-apoptotic signals like p53 and caspase-3 — the reading is that it may support the cell-renewal side of connective-tissue maintenance rather than acting as an anti-inflammatory.
This is early-stage, mechanism-focused research. Published human posology for subcutaneous Cartalax is limited, and the dosing framework that circulates is extrapolated from preclinical and observational sources rather than a controlled human dose-finding study — worth knowing before treating any specific number as settled.
Typical dosing & reconstitution
Cartalax is reconstituted with bacteriostatic water — a 20 mg vial in 3 mL gives roughly 6.67 mg/mL, where one insulin-syringe unit is about 66.7 mcg.
| Weeks | Daily dose | Units (U-100) ≈ |
|---|---|---|
| Weeks 1–2 | 2.0 mg | 30 units (0.30 mL) |
| Weeks 3–4 | 3.0 mg | 45 units (0.45 mL) |
| Weeks 5–8 | 4.0 mg | 60 units (0.60 mL) |
| Weeks 9–12 | 5.0 mg | 75 units (0.75 mL) |
This dilution keeps each injection under roughly 1 mL, the practical ceiling for a comfortable subcutaneous shot. Run your own vial and water through the reconstitution calculator to confirm units.
Half-life & why it’s titrated over 12 weeks
No human half-life has been published for Cartalax. As a tripeptide, it’s expected to be broken down by circulating peptidases quickly — likely a matter of minutes — the same pattern assumed across this whole Khavinson bioregulator family.
The 12-week titration isn’t a pharmacokinetic requirement so much as a gradual-exposure approach: starting at 2 mg and stepping up every couple of weeks lets you assess tolerability before reaching the top of the studied range, which matters more when independent human safety data is this limited.
What to track & considerations
Reported tolerability is generally favorable, with injection-site reaction as the main practical issue. Because the evidence base is thin, starting conservatively and tracking how you actually feel carries more weight here than it would for a well-studied compound.
Worth tracking: which titration week you’re on, the dose that day, and — since the studied mechanism is connective-tissue focused — whatever joint or mobility marker motivated the protocol in the first place.
How to track Cartalax in Stackeddd
Log each dose against the titration week so you always know your current dose without re-checking a table, and watch the joint or mobility marker you’re actually tracking this for. Reconstitution math is set once per vial — dial it in and every week’s units follow automatically.

Frequently asked questions
What is Cartalax used for?
Cartalax is a Khavinson tripeptide bioregulator studied preclinically for cartilage and connective-tissue support, via fibroblast/chondrocyte proliferation markers and reduced pro-apoptotic signaling. Human trial data is limited.
What is the half-life of Cartalax?
No formal human half-life is published. As a tripeptide it’s expected to clear quickly (likely minutes) via normal peptidase breakdown, consistent with its once-daily dosing.
How long is a Cartalax protocol?
Titration schedules typically run about 12 weeks, stepping the dose up from 2 mg to 5 mg daily every two to four weeks.
How do you reconstitute Cartalax?
Add 3 mL of bacteriostatic water to a 20 mg vial for about 6.67 mg/mL — a 3 mg dose is then roughly 45 units on a U-100 insulin syringe.
