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

Cortagen effects

  • Reported support of cortical neuron function and gene expression
  • Improvements in memory and attention (Russian observational)
  • Neuroprotection in cerebral ischemia models
  • Possible support for post-stroke and post-concussive recovery
  • Modulation of neuroplasticity-related gene expression

Cartalax side effects

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

Cortagen side effects

  • Generally well-tolerated in Russian clinical use
  • Mild injection-site reactions
  • Limited Western safety validation
  • Possible mild sleep disturbance with late-day dosing

Cartalax vs Cortagen — common questions

What is the difference between Cartalax and Cortagen?

Cartalax: Khavinson short peptide bioregulator targeting chondrocytes and connective tissue. Typical dose 1,000-5,000 mcg. Cortagen: Khavinson short peptide bioregulator targeting cortical neurons and CNS gene expression. Typical dose 1,000-5,000 mcg. Both fall under the Bioregulators category.

Can you stack Cartalax and Cortagen?

Stacking Cartalax with Cortagen 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 Cortagen?

Cartalax is typically dosed: Once daily (SubQ) or sublingual for Joint / cartilage support. Cortagen is typically dosed: Once daily morning (SubQ) or intranasal for Cognitive support.

Are Cartalax and Cortagen FDA approved?

Cartalax: Not FDA approved. Cortagen: Not FDA approved.
