    Summary · context
    A retrospective study was done at the Institute for Hormonal Balance in Orlando, Florida, USA to see whether intra-articular injection of the peptide BPC 157, alone or combined with TB4, helped relieve knee pain.
    Summary · context
    Of the 17 patients in the study, 16 were contacted by phone to follow up on the status of their knee pain.

Studies that did not test the peptide alone4

In this study, the peptide was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking the peptide.
