Stimulates fibroblast activity, increasing collagen and proteoglycan synthesis

Summary

Cartalax is a synthetic short peptide bioregulator derived from cartilage tissue. It supports regeneration of the extracellular cartilage matrix, stimulates fibroblast and chondrocyte activity, and may alleviate symptoms of osteoarthritis and other degenerative joint diseases. Commonly used in short injectable cycles with minimal systemic side effects.

How it works

  • Stimulates fibroblast activity, increasing collagen and proteoglycan synthesis
  • Promotes chondrocyte proliferation and enhances cartilage matrix regeneration
  • Modulates inflammation by regulating cytokine and matrix metalloproteinase expression

Dosing

  • unit: mg
    low dose: 2
    frequency: Daily
    high dose: 6
    standard dose: 4
    administration route: Subcutaneous (SQ)

Cycling

  • Inject 200 mcg daily for 10–20 days. Repeat every 3–6 months for chronic joint health maintenance. Split into 2–3 smaller daily doses if needed.

Side effects

common: ["Transient fatigue, mild flu-like sensation (user-reported)","Mild digestive upset, rare (user-reported)"]

Chemistry & PK

sequence: Short peptide bioregulator of cartilage tissue
half life: Approximately 24 hours
degradation: Rapid enzymatic degradation unless administered subcutaneously
molecular formula: Not fully disclosed (synthetic peptide complex)
tissue specificity: High specificity for cartilage, connective tissue, and synovial environments
