Comparison

CJC-1295 vs Epitalon

Function

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, Epitalon is reported to increase lifespan and reduce tumor incidence in animals, and to influence differentiation of neural and mesenchymal stem cells; is studied as an epigenetic regulatory peptide36.

Mechanism

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, Epitalon is a synthetic tetrapeptide, Ala-Glu-Asp-Gly (AEDG), that has been shown to bind histones and modulate gene expression and chromatin state, with reported effects on pineal function, neurogenesis, and longevity in animal models36.

Length and Sequence

CJC-1295 is 29 amino acids long, whereas Epitalon is shorter as it has a length of 4 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. Epitalon is made up of a sequence of Alanine, Glutamic acid, Aspartic acid, Glycine.

Receptor

CJC-1295

Growth hormone–releasing hormone receptor (GHRHR) on anterior pituitary somatotrophs1094103

Epitalon
