An underground economy for unlicensed slimming drugs is being driven by social media fitness personalities and sellers on messaging platforms, according to recent findings.
Experimental Treatment Acquiring Popularity Online
The experimental drug, which remains in research studies, is being advertised by social media influencers for its supposed fat-burning effects. Followers are urged to message these profiles directly for supplier links, while also receiving discount codes.
Active Trade on Messaging Platforms
Additionally, a robust trade exists on messaging services, where groups with thousands of participants share comparison images, injection guides and assertions of rapid British shipping. Sellers market the substance there before redirecting customers to other platforms for transactions.
Learning About Retatrutide
Retatrutide is an experimental injection created by American pharmaceutical company Eli Lilly. The treatment affects three gut hormones – GLP-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Preliminary studies indicate it could assist patients lose up to a quarter of their total weight. Referred to as the “triple G”, the drug is being hailed digitally as the successor to Ozempic.
Medical Experts Express Concerns
However, physicians and pharmacists have cautions that the sale of what is still an unlicensed medication in the United Kingdom is a cause for concern and could lead to users injecting substances of uncertain source.
Several professionals stated the popularity for the experimental drug could be linked to the rising price of licensed weight loss products such as Mounjaro.
Regulatory Status and Enforcement
Marketing retatrutide on TikTok or Telegram is prohibited in the UK, as it is an unapproved medication that must not be promoted or supplied for human use under the British medical regulations.
Some influencers try to circumvent the regulations by referring to the drug as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a restricted substance, but advertising and supply can still breach medicines, advertising, and consumer laws, risking penalties, prosecution or imprisonment.
Platform Reaction and Content Elimination
According to the social media company, the service has removed problematic content and prohibited related keywords and query recommendations. The organization said it was committed to keeping the service secure and investing in strengthening enforcement strategies.
Online Marketplace Activities
Research also discovered groups with up to 9,000 members selling retatrutide using Telegram's integrated discovery tool, which operates like a public directory. Entering “retatrutide” instantly displays groups with thousands of members, filled with photos of weight loss, positive testimonials and step-by-step instructions for preparing or administering at home.
Within minutes of joining one community, a vendor shared WhatsApp details, where most purchases occur. The seller sent an guidebook and promised delivery within 48 hours. When asked whether the product was authentic, one vendor responded: “You can’t be sure.” Another shared a image of a supposed laboratory certificate. Not one inquired about weight, health issues or previous experience.
Item Information and Costs
Within these groups, posts show dark colored packages with Royal Mail labels, claiming to contain new batches. One message read: “It took eight of us to load them this morning.”
Buyers can select between powder vials, prepared at home with sterile water, or pre-filled pens usually sold at 160 pounds for 20mg. When asked how much time a pen should last, sellers give contradictory answers varying between a few weeks to “depends on your body”.
Service Moderation and Security Measures
A representative for the messaging service stated it regularly monitored dangerous content on its service including material that encouraged the “misuse of controlled medications”. The organization noted that it eliminated “millions of pieces of harmful content each day”.
Medical Expert Cautions
“People are administering materials they cannot confirm. Although the research behind this drug is sound, these digital versions may not include what they claim,” said a pharmacy expert, the director of pharmaceutical services at Chemist4U.
Dr Crystal Wyllie of an online medical service linked the surge in interest to current price rises for approved slimming medications such as Mounjaro. “With costs rising, patients are turning to online platforms. But counterfeit injections are extremely risky. You can’t be certain what’s inside or whether the environment they were made in was clean,” she explained.
Her team has previously encountered patients injured by self-injection from unconfirmed sources. “We understand the frustration, but buying from messaging apps or WhatsApp is gambling with your well-being,” said Wyllie. “These materials could be contaminated or improperly measured.”
Manufacturer Position
A spokesperson from the pharmaceutical company stated the substance was in phase 3 clinical trials and had not been evaluated or approved by any government authority anywhere in the world. “Consequently at this time no one can market [it] for human use,” they explained, adding that any product “misleadingly claiming itself as a company experimental product not yet approved … may subject users to potentially serious medical dangers”.
