Teens chase rapid body changes by buying unregulated peptides online

A growing number of teens are injecting black-market peptides they find on social media—such as retatrutide and melanotan—for quick weight loss and tanning. Sourced through informal networks like Telegram, these products are often labeled “not for human consumption” and used in DIY stacks, with minimal medical oversight and unknown long-term health risks. Experts warn that adolescence is a critical development period, and unregulated, rapidly acting peptides can have serious consequences, including hormonal disruption, cardiovascular issues, and skewed body image driven by looksmaxxing culture.
