Cartalax effects

  • Reported support of chondrocyte function and cartilage matrix synthesis
  • Improvements in joint pain and mobility (Russian observational)
  • Possible slowing of age-related cartilage degradation
  • Recovery support after cartilage injury
  • Modulation of connective-tissue gene expression

Crystagen effects

  • Reported improvement in T-cell numbers and function
  • Restoration of age-related immune decline (Russian observational)
  • Support of thymic function in elderly patients
  • Anti-inflammatory effects
  • Recovery support after severe illness

Cartalax side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation

Crystagen side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Theoretical: caution in active autoimmune disease (immune modulation)

Cartalax vs Crystagen — common questions

What is the difference between Cartalax and Crystagen?

Cartalax: Khavinson short peptide bioregulator targeting chondrocytes and connective tissue. Typical dose 1,000-5,000 mcg. Crystagen: Khavinson short peptide bioregulator targeting thymus / immune cells. Typical dose 1,000-5,000 mcg. Both fall under the Bioregulators category.

Can you stack Cartalax and Crystagen?

Stacking Cartalax with Crystagen is a protocol-design question best raised with a clinician — it depends on your goal, current bloodwork, and whether both peptides target overlapping mechanisms. Both peptides should be tracked independently with separate injection sites and timing. PinnyPeptide supports multi-peptide stacks with automatic injection site rotation.
