High copper levels may contribute to oxidative stress, neurological issues, or imbalances
Interestingly, the nitric oxide (NO) system blockade L-NAME can partially reverse this protective effect including reduction of gastric ulcer recurrence rate and ulcer indexes induced by BPC 157 (Table 2, Figure 1)
Mel Gibson has reportedly credited it
In these studies, BPC-157 has shown remarkable success in healing gastric ulcers, repairing damaged intestinal tissue, and even helping with inflammatory conditions

Where People Buy Peptides: Online "research chemical" suppliers No prescription needed Sold as vials of powder You reconstitute with sterile water Quality unknown Purity unknown 12-58% of supplements are contaminated with unlisted substances Compounding pharmacies (illegally) Some still compound banned peptides Higher quality control (theoretically) Requires prescription Legal risk for pharmacy and doctor Anti-aging/wellness clinics Cash-pay practices May source from gray market Charge $500-2,000+ per month Often stack multiple peptides Black market / gym dealers Sold alongside anabolic steroids Zero quality control Highest contamination risk The Quality Control Problem FDA warnings: Compounded peptides may have impurities Manufacturing varies widely No standardization Cross-contamination possible Real risk: You're injecting a substance of unknown purity, made in facilities with unknown quality control, based on research that doesn't exist, for conditions that haven't been studied
