BPC-157 (Body Protection Compound-157) is a synthetic peptide consisting of 15 amino acids derived from a protective protein found naturally in human gastric juice
Many users report significant improvements in healing times, reduced pain, and enhanced mobility following treatment
The volume per injection is small, typically less than 0.5ml, making the process quick and relatively painless for most users
