It's a 15-amino acid chain: Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Asp Classification : Pentadecapeptide (15 amino acids) Origin : Derived from gastric cytoprotective compounds Primary targets : Tissue repair, angiogenesis, growth factor upregulation Primary use : Tendon, ligament, and connective tissue repair Why Tendon Repair Is Challenging Tendons have notoriously poor blood supply compared to muscle
Stable gastric pentadecapeptide BPC 157 and striated, smooth, and heart muscle
The two compounds are paired in this blend because their mechanisms are mechanistically complementary BPC-157 modulates nitric oxide signaling and growth factor expression to support gastrointestinal, vascular, and connective-tissue healing, while TB-500 sequesters G-actin to drive cell migration, angiogenesis, and post-injury tissue remodeling
However, some peptides like HGH and IGF-1 may require more precise dosing due to their potency
Dosing errors in either direction affect both safety and results
