  1. 01AnimalAnimal study (in vivo)Efficacy outcome

    In rats with colocutaneous fistula, BPC‑157 given parenterally or perorally accelerated healing of the colonic and skin defect, leading to suitable closure of the fistula.

    In plain wordsIn rats with a gut-to-skin fistula, BPC‑157 sped up healing of the gut and skin defects and closed the fistula.
