BPC-157 is a synthetic 15-peptide derived from gastric juice protein. It has attracted much attention for its remarkable wound healing ability. It can effectively promote the repair and healing of various tissues such as tendons, gastrointestinal fistulas and skin. Its mechanisms of action are diverse, including promoting angiogenesis, stimulating growth hormone receptor expression, and having a positive effect on the central nervous system through the serotonin and dopamine systems, thereby showing therapeutic potential in stroke, spinal cord injury and schizophrenia models. In addition, the peptide also has anti-ulcer effects, protects the gastrointestinal mucosa, resists damage caused by various toxins (such as NSAIDs, insulin overdose and copper poisoning), and improves behavioral disorders caused by damage to specific neurotransmitter systems. BPC-157 can remain stable and effective in the absence of a carrier and has good oral bioavailability.
