TB-500 TB-500 (TB500) TB-500 (Thymosin Beta-4 Fragment) 5mg or 10mg (Lyophilized Peptide) For Research Use Only TB-500 is a synthetic Thymosin Beta-4 fragment studied in preclinical models for its roles in actin-binding dynamics, cell migration, angiogenesis, and tissue repair signaling

any human use for muscle growth occurs off-label and outside FDA-reviewed clinical protocols

That said, the combination itself has not been clinically validated there are no controlled human trials of this specific blend, and the supporting data for each peptide is largely preclinical (animal) work and anecdote
