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

Thymalin effects

  • Reported improvement in T-cell numbers (especially CD4+)
  • Improvement in CD4/CD8 ratio
  • Enhanced NK-cell function
  • Reduction in infection rates in immunocompromised patients
  • Long-term observational reduction in mortality (Khavinson 2003 study)
  • Anti-inflammatory effects

Cartalax side effects

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

Thymalin side effects

  • Generally well-tolerated across 40 years of Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Caution in active autoimmune disease

Cartalax dosing ranges

Joint / cartilage support

1-5 mg · Once daily (SubQ) or sublingual · 10-20 day cycles, repeated 2-3 times per year

Thymalin dosing ranges

Immune support (Russian clinical)

5-30 mg · Once daily IM or SubQ · 5-10 day course, repeated 2-3 times per year

Cartalax vs Thymalin — common questions

What is the difference between Cartalax and Thymalin?

Cartalax: Khavinson short peptide bioregulator targeting chondrocytes and connective tissue. Typical dose 1,000-5,000 mcg. Thymalin: Original Khavinson thymic peptide complex — multi-peptide immunomodulator with 40-year Russian clinical track record. Typical dose 5,000-30,000 mcg. Both fall under the Bioregulators category.

Can you stack Cartalax and Thymalin?

Stacking Cartalax with Thymalin 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.

Which is dosed more frequently, Cartalax or Thymalin?

Cartalax is typically dosed: Once daily (SubQ) or sublingual for Joint / cartilage support. Thymalin is typically dosed: Once daily IM or SubQ for Immune support (Russian clinical).

Are Cartalax and Thymalin FDA approved?

Cartalax: Not FDA approved. Thymalin: Not FDA approved.
