BB20 is a research-grade peptide blend containing 10 mg of BPC-157 and 10 mg of TB-500 per vial. BPC-157 is a synthetic pentadecapeptide derived from a gastric protein fragment, commonly used in animal experiments and some in vitro studies on tissue repair, inflammation modulation, microcirculation, and gastrointestinal models. TB-500 is a synthetic analog of the core functional region of natural thymosin beta-4 (Tβ4), frequently employed in laboratory research on cell migration, actin regulation, angiogenesis, and soft tissue regeneration. The combination of these two peptides is often utilized in studies focusing on tissue repair, inflammatory responses, soft tissue regeneration, and injury repair mechanisms.
