      Product Detail  


    Cortagen is a bioregulatory peptide that acts primarily on the brain and central nervous system. Studies have shown that it is a powerful regulator of inflammatory responses, especially in the nervous system, helping to restore the balance and normal function between pro-oxidant and antioxidant processes. Cortagen stimulates the expression of interleukin-2 and helps regulate immune function primarily by reducing autoimmune responses.
