GHRP-2 (growth hormone-releasing peptide 2) also called pralmorelin is a GHS (growth hormone secretagogue) used as a diagnostic agent. Growth hormone secretagogues are a product acting as secretagogues (that is, induce the secretion of GH (growth hormone).
What Is Growth Hormone-Releasing Peptide 2?
It’s a peptide that stimulates your body’s growth hormone (also known as somatotropin or human growth hormone) production. It’s one of the most effective and powerful preparations of the GHRP group, excelling in efficiency Ipamorelin and growth hormone-releasing peptide 6 (GHRP-6 or growth hormone-releasing hexapeptide) by approximately 30 per cent.
Its action is typically caused by the hypothalamus and pituitary stimulation, leading to an increased secretion of GH in 7 to 15 times, while the other stimulators of GH, based on the gamma-Aminobutyric acid (GABA or γ-aminobutyric acid) and amino acid level, don’t provide an increase that is more than 2 to 3 times.
The hypophysis (pituitary gland) is an endocrine gland that is roughly the size of a pea. It weighs 0.018 oz (0.5 grams) in the human body. It is located in the centre of the brain, and its function is to regulate the production of hormones of most of the endocrine glands.
The hypothalamus is the portion of the diencephalon (a division of the forebrain), the main centre of the ANS or autonomic nervous system (ANS, which humans don’t control, regulates blood circulation, metabolism organs, reproduction, excretion, digestion as well as respiration), controls sleep cycle, hormone levels and much more.
Hence, the peptide interacts with growth hormone secretagogue receptors (ghrelin receptors) and causes increased appetite.
