As interest in peptides has grown, so has confusion. Many people encounter BPC-157 alongside other peptides and assume they all function similarly. In reality, peptides vary widely in purpose, biological role, and research context.
Some peptides are studied for hormonal signaling. Others for metabolic regulation. Some influence appetite, growth pathways, or immune signaling. BPC-157 stands out because it is not primarily a hormonal or performance-oriented peptide, yet it is frequently grouped with them.
This article exists to clarify that difference.
Rather than asking, “Which peptide is best?”, a better question is:
What role is each peptide studied for—and how does BPC-157 differ from the rest?
