Overview
BPC-157 and TB-500 are two of the most researched peptides for tissue repair and healing. While they share some similarities, they have distinct mechanisms and research applications.
BPC-157 (Body Protection Compound)
- Origin: Derived from human gastric juice
- Sequence: 15 amino acids
- Primary Research Focus: Gut healing, tendon/ligament repair, wound healing
- Mechanism: Promotes angiogenesis, modulates growth factors
- Stability: Highly stable, can be taken orally or injected
TB-500 (Thymosin Beta-4)
- Origin: Naturally occurring in human and animal cells
- Sequence: 43 amino acids
- Primary Research Focus: Muscle repair, cardiac tissue, hair growth
- Mechanism: Promotes cell migration, reduces inflammation
- Stability: Must be injected; not orally bioavailable
