Avoid purchasing and injecting unregulated peptides sold online, as they lack scientific evidence in humans and present serious risks of contamination, incorrect dosage, and impurities.

Adrian Chavez's warning is scientifically very sound and accurately reflects the documented risks. A vast chemical analysis study published in April 2026 on more than 6,400 samples of gray-market peptides (such as BPC-157) revealed that 41.6% to 71.1% of them did not meet basic quality criteria, and 15% showed bacterial contamination. Furthermore, regulatory agencies such as Health Canada and the FDA reiterate that these substances sold online under the label 'for research purposes' bypass standard safety controls. Regarding efficacy, a 2025 literature review on BPC-157 shows that evidence of benefits for physical recovery relies almost exclusively on animal models, with rigorous human trials being virtually nonexistent. Finally, the Harvard T.H. Chan School of Public Health emphasizes that the injection of these untested molecules can disrupt the body's natural defense system. The lack of long-term data on the dosages and purity of these unregulated products therefore fully justifies avoiding self-experimentation.
