Cartalax vs Semax
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Cartalax is a tetrapeptide bioregulator (Ala-Glu-Asp-Pro) developed by Professor Vladimir Khavinson for cartilage and connective tissue. It is tissue-specific for chondrocytes and cartilaginous structures, supporting cartilage matrix synthesis, slowing degenerative changes, and promoting joint longevity. It is used in the context of osteoarthritis, joint aging, and athletic cartilage preservation.
- Semax is a synthetic heptapeptide derived from ACTH developed in Russia. It is a potent nootropic that enhances memory, focus, and provides neuroprotection. Approved in Russia for cognitive disorders, stroke recovery, and traumatic brain injury.
- Half-Life
- Short (minutes); gene-regulatory effects are sustained
- Minutes (but effects persist for hours via BDNF induction)
