Summary

GHRP-2 (pralmorelin) is a synthetic growth hormone-releasing peptide and GHS-R agonist developed primarily as a diagnostic agent for hypothalamic-pituitary function; it was awaiting approval in Japan for this diagnostic indication and underwent phase II trials for short stature, while US development for GH deficiency was discontinued [1]. In a controlled human study, GHRP-2 infusion increased food intake by roughly 36% versus saline in healthy men and significantly raised serum GH levels, paralleling effects reported for ghrelin [2]. Preclinical work indicates GHRP-2 can directly act on myocytes to attenuate muscle-atrophy-related ubiquitin ligases [4]. The remaining literature concerns urinary detection of GHRP-2 in anti-doping testing rather than therapeutic efficacy [3]. Human evidence for GHRP-2 as an administered therapeutic is therefore limited, anchored mainly in diagnostic use and small mechanistic studies [1,2].
