A connective tissue bioregulator that supports cartilage matrix synthesis and joint health.
A synthetic tetrapeptide bioregulator (Ala-Glu-Asp-Pro) targeting cartilage and connective tissue. Research suggests it stimulates chondrocyte and fibroblast expression of collagen, proteoglycans, and hyaluronic acid — components essential for cartilage matrix integrity and joint lubrication.
Used in Russian bioregulator protocols for musculoskeletal ageing, often combined with Testagen and other bioregulators in comprehensive longevity stacks. The research base is primarily Russian and Eastern European.
Regular use is proposed to slow articular cartilage degradation associated with ageing, trauma, and inflammatory joint disease, though independent replication in Western peer-reviewed literature remains limited.
