A precisely trimmed form of IGF-1 - IGF-1 DES comprises of a tri-peptide structure containing the molecules of Glycine-Proline-Glutamine. Used in the in vivo studies, IGF-1 DES 1mg has been used in brains of humans, bovine colostrums, and uterus of pigs. When combined with the in vitro studies, the usage of IGF-1 DES suggested that this peptide was more potent that the original IGF-1. IGF-1 DES was found to be active in triggering the hypertrophy and proliferation in cultured cells. This effect is induced into the cells by IGF-1 DES by alteration of the molecular sequence the originally circulating IGF-1 through the action of protease enzyme. IGF-1 DES 1mg can be purchased in its purest form through Pinnacle Peptides at attractive prices Originally extracted from E. coli - Insulin like Growth Factor (IGF)-1 DES comprises of 67 amino acids that are linked through a polypeptide chain. The extraction of this peptide from the original IGF-1 protein gave it a more stable and functional
