“BPC-157 peptide supplements sold online have been found to contain lead and other contaminants.”

The evidence supports general contamination concerns for unregulated online supplements but does not substantiate the specific claim that BPC-157 products have been analytically confirmed to contain lead. The most authoritative sources use conditional language like "potential contamination" and "may be tainted," while the only BPC-157-specific testing dataset (469 samples across 69 vendors) reports purity variability but no lead detections. Lead contamination data cited in the evidence pertains to protein powders and dietary supplements broadly, not BPC-157 specifically.

“BPC-157 and TB-500 peptide supplements are FDA-approved and have been scientifically proven to heal injuries and slow aging in humans.”

This claim is false on both of its core assertions. Neither BPC-157 nor TB-500 holds FDA approval for any therapeutic indication — the 2026 Category 1 reclassification permits compounding under physician oversight but is explicitly not FDA approval. The "scientifically proven" claim is equally unsupported: human evidence consists only of small, uncontrolled pilot studies, with no large-scale randomized controlled trials, and there is no human clinical evidence for anti-aging effects.
