TB-500 — Mechanism of Action
TB-500 (Thymosin Beta-4) is a 43-amino acid peptide that sequesters G-actin monomers to regulate actin polymerization, promoting cell migration and proliferation. It activates integrin-linked kinase (ILK) and Akt phosphorylation for cell survival signaling, reduces inflammation via NF-kB pathway modulation, and promotes blood vessel formation.

BPC-157 — Mechanism of Action
BPC-157 is a synthetic pentadecapeptide derived from human gastric juice protein. It promotes healing through upregulation of the FAK-paxillin pathway and VEGF-mediated angiogenesis, activates the JAK-2/STAT-3 signaling cascade, enhances nitric oxide synthesis via the Akt-eNOS axis, and upregulates growth hormone receptor expression.
