Comparison
While CJC-1295 is used in research to chronically elevate endogenous growth hormone and IGF-1 levels, enabling studies of body composition, metabolic, and anti-aging effects of prolonged GH exposure10, TB-500 is studied for enhancing musculoskeletal and cardiac repair, wound healing, and promoting cell migration and differentiation via actin cytoskeleton remodeling21255.
While CJC-1295 works as a tetrasubstituted 29-amino-acid analog of GHRH(1–29) that acts as a potent agonist at the GHRH receptor and, in its DAC form, covalently binds serum albumin to extend half-life from minutes to days, resulting in sustained pulsatile GH and IGF-1 increase1082, TB-500 is a synthetic peptide comprising the LKKTETQ actin-binding motif of thymosin beta-4 that binds G-actin, sequesters actin monomers, and promotes cell migration, angiogenesis, and tissue repair1255.
CJC-1295 is 29 amino acids long, whereas TB-500 is shorter as it has a length of 7 amino acids. CJC-1295 is made up of a sequence of Tyrosine, Alanine, Aspartic acid, Alanine, Isoleucine, Phenylalanine, Threonine, Glutamine, Serine, Tyrosine, Arginine, Lysine, Valine, Leucine, Alanine, Glutamine, Leucine, Serine, Alanine, Arginine, Lysine, Leucine, Leucine, Glutamine, Aspartic acid, Isoleucine, Leucine, Serine, Arginine. TB-500 is made up of a sequence of Lysine, Lysine, Lysine, Threonine, Glutamic acid, Threonine, Glutamine.
