In the past, individuals sought unconventional treatments like crocodile dung, tapeworms, and raw meat facials to maintain youth and vitality. Today, some influencers promote injectable peptides as a solution, but scientific evidence does not fully support these claims.
While established injectable peptides such as insulin and GLP-1s are used in medicine, the peptides endorsed by influencers lack approval from Health Canada and lack extensive human trials. These unregulated peptides are often obtained through a “grey market,” legally intended for research but used for other purposes. Health Canada issued warnings in April 2025 and August against purchasing these unauthorized drugs online, and globally, the World Anti-Doping Agency has banned several injectables for athletes.
In contrast, the U.S. is considering easing FDA regulations on compounding popular peptides by pharmacies. However, experts caution against the use of unapproved injectables due to potential health risks and lack of scientific backing.
Peptides are amino acids that regulate bodily functions at the molecular level. Some synthetic injectable peptides are marketed as muscle enhancers or youth-promoting agents, but the evidence supporting these claims is scarce. Tim Caulfield, a health law expert, describes the current trend as “science-ploitation,” where genuine research is exploited for commercial gain.
Injectable peptides carry risks as their production is largely unregulated, raising concerns about sterility and product authenticity. The lack of oversight poses dangers such as bacterial infections and uncertain biological effects. Experts emphasize the importance of avoiding unproven pharmaceuticals and highlight the effectiveness of traditional health practices like exercise, nutrition, and adequate rest over unverified shortcuts.
In conclusion, the allure of injectable peptides as a shortcut to youth and fitness is met with skepticism by health professionals, urging caution and emphasizing the value of evidence-based health practices.
