Responsible Practice assessment
Material concerns- · Displays customer reviews describing real personal injury-recovery results ("insane results on a shoulder injury") -- vendor chose to keep these live.
- · Benefit-claim language observed on site: "Customer review quotes displayed on the BPC-157 product page: "this has improved my shoulder 75%"; "Insane results on a should[er] injury which I was looking at surgery for"; "helps massively control pain and discomfort of my arthritic shoulder"; "good for ligaments repair". These are user-submitted reviews, not vendor copy -- official product description itself stays research-framed."
