Comparison
While GHRP-6 is used experimentally to produce strong GH surges and hyperphagia, allowing investigation of GH-dependent anabolism and energy-balance regulation2030, Selank is a peptide developed in Russia as an anxiolytic and nootropic; in animal models it reduces anxiety-like behavior and modulates immune parameters under stress39.
While GHRP-6 works as a first-generation synthetic hexapeptide ghrelin mimetic that potently stimulates GH release and markedly increases appetite via GHSR-1a activation in hypothalamus and pituitary203096, Selank is a synthetic heptapeptide, Thr-Lys-Pro-Arg-Pro-Gly-Pro, that combines a tuftsin fragment with a Pro-Gly-Pro motif and is reported to modulate GABAergic neurotransmission and cytokine balance while being resistant to proteolytic degradation39.
GHRP-6 is 6 amino acids long, whereas Selank is longer as it has a length of 7 amino acids. GHRP-6 is made up of a sequence of Histidine, Tryptophan, Alanine, Tryptophan, Phenylalanine, Lysine. Selank is made up of a sequence of Threonine, Lysine, Proline, Arginine, Proline, Glycine, Proline.
