In the preclinical literature it is described across six complementary axes: angiogenesis via VEGFR2/eNOS/NO, regulation of FAK-paxillin signalling, protection of the endothelium and the gastric-intestinal mucosa, modulation of the brain-gut axis with the NO pathway, tendon maturation with fibroblast proliferation, and cytoprotection as a common denominator
It is chemically a true peptide (six amino acids, including two D-amino acid substitutions for stability), so unlike some non-peptide GH secretagogues it is correctly classified in this category
