Animal studies have demonstrated BPC-157's cytoprotective effects against NSAID-induced gastric lesions, alcohol-induced stomach damage, stress ulcers, and models of inflammatory bowel disease (ulcerative colitis and Crohn's disease)

Moreover, GH signaling to elicit IGF1 gene transcription is blocked in the absence of appropriate insulin signaling, a phenomenon also known as un-coupling, and resulting in growth arrest (60, 61, 63, 64) (Figure 3)
