TB4 (TB-500)
10mg · 2ml
SKU: tb4-10mg
TB-500 (Thymosin Beta-4) is a peptide derived from the naturally occurring Thymosin Beta-4 protein that plays a key role in cell migration, tissue regeneration, and inflammation reduction. It operates through actin sequestration to facilitate cellular migration to injury sites, promote angiogenesis, and enhance tissue remodeling.

BPC-157 (Body Protection Compound-157) is a synthetic pentadecapeptide studied for its role in tissue repair, particularly in soft tissue, GI mucosal, tendon, ligament, and muscle injury models. Its proposed mechanism involves nitric oxide signaling and angiogenesis-related pathways to modulate inflammation and promote healing.
