  • stimulation of muscle growth, even in older athletes. The peptide has an active influence on the growth of muscle fibers;
  • reduction in the percentage of body fat;
  • charge of the body with energy;
  • improves the delivery of amino acids and glucose;
  • accelerates the synthesis of RNA.

It is believed that IGF-1LR3 shows better fat loss results than even somatotropin.
