A shadow market for unapproved weight-loss medications is being driven by social media fitness personalities and vendors on communication apps, based on new investigations.
Retatrutide, which remains in clinical trials, is being promoted by social media influencers for its supposed fat-burning properties. Viewers are urged to contact these accounts directly for source information, while also obtaining discount codes.
Additionally, a flourishing market exists on messaging services, where communities with thousands of participants share comparison images, administration instructions and claims of rapid British shipping. Sellers market the drug there before directing customers to WhatsApp for transactions.
This medication is an experimental injectable developed by US drugmaker Eli Lilly. The drug affects three intestinal hormones – GLP-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Early trials indicate it could help patients lose up to a quarter of their total weight. Nicknamed the “triple G”, the drug is being promoted digitally as the successor to Ozempic.
However, doctors and chemists have warned that the distribution of what is still an unlicensed drug in the UK is a cause for concern and could result in individuals administering products of unknown origin.
Some experts said the popularity for the experimental drug could be connected to the rising price of licensed weight loss treatments such as Mounjaro.
Marketing the unapproved drug on TikTok or messaging apps is illegal in the UK, as it is an unlicensed medication that cannot be promoted or distributed for human use under the Human Medicines Regulations 2012.
Some influencers try to sidestep the regulations by calling to the drug as a “research chemical” or citing it as “not for human consumption”. The substance is not a controlled substance, but promotion and supply can still violate pharmaceutical, advertising, and consumer regulations, risking fines, prosecution or imprisonment.
Based on TikTok, the service has removed problematic material and prohibited related hashtags and query recommendations. The organization said it was committed to maintaining the platform secure and allocating resources in enhancing compliance measures.
Investigations also found groups with up to nine thousand participants selling retatrutide using the platform's built-in discovery tool, which operates like a public directory. Typing “retatrutide” immediately displays channels with thousands of users, filled with photos of weight loss, glowing testimonials and detailed guides for mixing or injecting at home.
Within minutes of joining one group, a seller shared contact information, where the majority of purchases take place. The seller provided an guidebook and promised shipping within 48 hours. When asked whether the substance was authentic, one vendor responded: “You can’t be sure.” Another provided a image of a supposed testing documentation. Not one asked about weight, medical conditions or past usage.
Inside these communities, posts display black plastic parcels with postal service stickers, stating to contain fresh supplies. One communication read: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, prepared at residence with sterile water, or ready-to-use injectors typically sold at 160 pounds for 20 milligrams. When asked how long a pen should last, vendors give contradictory answers ranging from a several days to “depends on your body”.
A spokesperson for Telegram stated it actively monitored dangerous content on its service including content that encouraged the “misuse of controlled medications”. The organization noted that it eliminated “millions of pieces of harmful content each day”.
“Individuals are administering materials they can’t verify. Even if the science behind this drug is valid, these online products may not include what they advertise,” said Jason Murphy, the head of pharmacy at a pharmacy service.
Dr Crystal Wyllie of Asda Online Doctor connected the surge in demand to current cost increases for authorized slimming drugs such as Mounjaro. “With prices rising, individuals are turning to online platforms. But fake treatments are extremely dangerous. You cannot know what’s inside or whether the environment they were made in was clean,” she explained.
Her staff has already seen individuals injured by self-injection from unverified sources. “We recognize the frustration, but buying from Telegram or communication platforms is taking chances with your health,” stated the doctor. “These substances could be impure or incorrectly dosed.”
A representative from Eli Lilly said the substance was in third stage clinical trials and had not been evaluated or approved by any regulatory agency anywhere in the world. “Consequently at this time no one can sell [it] for human use,” they explained, adding that any item “falsely representing itself as a company investigational substance not yet approved … may subject users to possibly serious health risks”.
