Regulatory experts and health officials in the UK have expressed alarm about the proliferation of experimental peptides and anabolic steroids being sold online, noting gaps in oversight that create significant public health risks.
Prof Channa Jayasena of Imperial College London, who works as a consultant in reproductive endocrinology and andrology, stated he encounters patients regularly who are taking experimental peptides. He highlighted particular dangers associated with these substances, noting that anabolic steroids are known to increase death risk threefold. Many peptides are manufactured in China without standard quality controls, creating contamination risks. Jayasena characterized the situation as lawless, with people injecting untested substances that contain powerful solvents potentially at hazardous concentrations.
The issue has been amplified by social media platforms, according to recent reporting. A Guardian investigation documented how fitness influencers use Telegram to market anabolic steroids, prescription medicines, and unregulated peptides. Prof Susan Backhouse of Leeds Beckett University attributed rising use to widespread body dissatisfaction and constant exposure to before-and-after imagery on social feeds. She emphasized that self-experimentation has become easier, with consumers able to purchase products through influencer links and receive them within days.
Multiple officials identified regulatory fragmentation as a core problem. The MHRA handles medicine regulation while the Advertising Standards Authority has limited scope, leaving gaps where medical claims by non-professionals occur without oversight. Layla Moran, Liberal Democrat chair of the health select committee, criticized technology firms for insufficient platform protections and described regulatory agencies as overwhelmed. Conservative MP Luke Evans, a former GP, called for awareness campaigns, data collection, and clarification of accountability.
Government officials responded that the MHRA’s criminal enforcement unit investigates suspected offences and that the Online Safety Act treats illegal drug sales as a priority.
