BPC-157 demonstrates exceptional safety in animal toxicology studies, with comprehensive evaluations in mice, rats, rabbits, and dogs failing to establish a lethal dose (LD) across wide dose ranges extending from standard research doses (6 g/kg) to levels exceeding 1000-fold higher concentrations (20 mg/kg), with no evidence of acute toxicity, organ-specific damage, or systemic adverse effects even following repeated high-dose administration
