The released acid, by penetrating the intestinal wall, lowers its local pH, thus preparing the small capsule containing the peptide and, in our case, the absorption enhancer which is carnitine
GHK-Cu is often described as a healing peptide, but results depend on context
A 2003 Achilles tendon study reported BPC-157 activity in transected rat Achilles tendon models, describing the peptide sequence and molecular weight and connecting it to tendon healing research
Within the GI system, BPC-157 has been characterised across stomach, duodenum, small intestine, colon, and oesophagus in models of ulceration, NSAID toxicity, ethanol damage, inflammatory bowel disease, and anastomotic healing, Tendon and ligament research represents the second most extensively documented tissue application
