BPC-157s evidence base is also concentrated in a single research group (Sikiric and colleagues, University of Zagreb) with limited independent replication
Use GHK-Cu as the anchor
If a patient receives two different drugs by separate injection on the same date, two units may be billed, but modifier 59 (or XS for Medicare) is required on the second unit to prevent a duplicate-service denial
