As a recently reviewed subject (Vukojevic et al., 2022), BPC 157 has been shown to reduce brain lesions, trauma-induced brain injury (Tudor et al., 2010), compression-induced spinal cord injury (Perovic et al., 2019), and stroke (Vukojevic et al., 2020)

BPC-157 in particular has been extensively investigated in rodent gastrointestinal models, with laboratory studies examining ulcer-healing endpoints, mucosal blood flow markers, and cytoprotective signaling in gut epithelial cell preparations

For instance, studies on tendon fibroblasts have shown that BPC 157 can accelerate tendon healing by enhancing collagen production and cellular proliferation
