BPC-157 and TB-500 are synthetic peptides studied for their regenerative and healing properties. BPC-157, derived from human gastric juice, supports tissue repair by enhancing angiogenesis, promoting fibroblast migration, and reducing inflammation through modulation of nitric oxide pathways and growth factor signaling.
 It has shown potential in accelerating healing of skin, muscle, tendon, ligament, and gastrointestinal tissues, with studies indicating its ability to stabilize the gastrointestinal mucosa and support gut health.
 TB-500, a synthetic version of Thymosin Beta-4, promotes cell migration and tissue regeneration by regulating actin polymerization and cytoskeletal organization, which aids in wound healing and reduces scarring.
 Both peptides stimulate blood vessel formation—TB-500 by upregulating vascular endothelial growth factor (VEGF), and BPC-157 by increasing VEGFR2 receptors—thereby improving blood flow to injured areas.
 Together, they are used in preclinical research for their complementary roles in cellular repair, tissue remodeling, and anti-inflammatory effects.
