Peptide Science Basics: Evidence-First Education on Peptides and Health

Key Takeaways BPC-157 and TB-500 are both peptides discussed for soft-tissue recovery, but they come from different biological families and act through different mechanisms. BPC-157 is a synthetic 15-amino-acid fragment derived from a protective protein found in gastric juice, and its research base leans toward gut, tendon, and ligament healing. TB-500 is a synthetic fragment of Thymosin Beta-4, a naturally occurring protein, and its research base leans toward cell migration,
