Peptides

GHRP-2 (Growth Hormone Releasing Peptide-2) is a hexapeptide which is considered a hormone secretagogue. The single polypeptide chain which is composed of six amino acids is a growth hormone releasing peptide. This peptide lacks opioid activity but is still a stimulator of GH release. It also works to regulate and correct production of low level growth hormone in test subjects. This amplification of the transduction pathway is what makes the study of this GHRP so fascinating to study. The peptide also limits the ability of somatostatin to reduce the limit of growth hormone levels. This allows more growth to be exerted during its biological half-life of 2.5 hours.
