Some patients in a small human study reported less knee pain after treatment involving BPC-157. The study followed reported pain and did not establish whether an injured tendon or ligament healed.
What researchers studied
Researchers looked back at records from patients treated for different types of knee pain. Some received BPC-157 alone and others also received thymosin beta-4. There was no placebo group.
What patients experienced
Patients described changes in pain at follow-up. Because the study was small and included different conditions and treatments, it could not isolate the effect of BPC-157. A controlled trial measuring pain, function and tissue healing would answer a different question.
