Cartalax

In plain English

Cartalax is a very short peptide developed in Russia as a bioregulator for cartilage and connective tissue. It is used to support joints, especially with age or wear.

What it's used for

  • Joint and cartilage support
  • Connective tissue health
  • Healthy aging

Benefits

In cell studies, Cartalax supported the growth and function of cartilage cells and reduced markers of cell aging. Users report less stiffness and more comfortable joints after a course.

How it works

In simple terms: it is thought to help cartilage cells act younger.

Like other Khavinson bioregulators, it is thought to influence gene activity in its target tissue, supporting cartilage cell renewal and reducing aging-related changes.

Development history

  • 2000s: Developed at the St. Petersburg Institute of Bioregulation and Gerontology.

Typical protocols

Educational information only, not medical advice. The information below describes how this peptide has been used in research, on prescription labels or by users. It is not a recommendation. Talk to a qualified healthcare professional before starting, stopping or changing anything.

Doses vary; these ranges are what users commonly report.

Use Dose Frequency Length
Joint support 1–2 mg Daily 10–20 days

Cycling

Short courses repeated once or twice a year.

Administration options

Subcutaneous injection.

Reconstitution and dosing calculator

Usually comes in 10 mg or 20 mg vials, mixed with 2 mL of bacteriostatic water.

1Peptide in the vial

The total amount printed on the vial label.

2Bacteriostatic water added

More water makes each dose a bigger, easier-to-measure draw. It does not change how much peptide is in the vial.

3Dose per injection

Use the dose from your protocol or your clinician. 1 mg = 1,000 mcg.

4Your syringe

All three are U-100 insulin syringes: 100 units = 1 mL. Smaller barrels make small doses easier to read.

    Side effects and safety

    • Users report it is generally well tolerated.
    • Very little safety data in people.
    • Avoid during pregnancy and breastfeeding.

    Common stacks

    BPC-157 and TB-500: for joint and tendon healing.

    Storage

    Powder: refrigerate or freeze. After mixing: refrigerate at 2–8 °C and use within about 3 weeks.

    Compare with

    BPC-157: a broader healing peptide with much more research.

    Frequently asked questions

    How is it different from BPC-157?

    Cartalax is a tiny bioregulator aimed at cartilage over time; BPC-157 is used to speed up healing of injuries.
