An underground economy for unlicensed weight-loss drugs is being driven by TikTok fitness influencers and vendors on messaging platforms, according to new investigations.
Retatrutide, which is still in clinical trials, is being advertised by social media influencers for its alleged weight-reducing properties. Followers are encouraged to message these profiles directly for supplier links, while also obtaining discount codes.
Separately, a robust market exists on Telegram, where groups with numerous of participants share “before and after” images, administration instructions and assertions of rapid British shipping. Sellers market the drug there before directing buyers to other platforms for transactions.
This medication is an experimental injectable developed by American pharmaceutical company Eli Lilly. The drug affects three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Preliminary studies suggest it could assist patients reduce 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.
Nevertheless, physicians and pharmacists have warned that the sale of what remains an unlicensed medication in the United Kingdom is a cause for concern and could result in individuals injecting substances of unknown origin.
Several professionals said the popularity for the experimental drug could be connected to the rising cost of approved weight loss treatments such as Mounjaro.
Selling retatrutide on social media or Telegram is prohibited in the UK, as it is an unlicensed drug that must not be promoted or distributed for personal consumption under the British medical regulations.
Some influencers attempt to sidestep the rules by calling to the substance as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled substance, but advertising and supply can still breach medicines, advertising, and customer regulations, potentially leading to fines, prosecution or prison.
According to the social media company, the service has taken down problematic material and prohibited associated hashtags and search suggestions. The organization said it was committed to maintaining the platform secure and investing in enhancing compliance measures.
Research also found communities with up to 9,000 members marketing retatrutide using the platform's built-in discovery tool, which functions like a online catalog. Entering “retatrutide” instantly displays channels with thousands of members, filled with images of slimming results, positive reviews and step-by-step guides for mixing or administering at home.
Within moments of entering one group, a vendor shared WhatsApp details, where most purchases take place. The seller sent an instruction manual and guaranteed shipping within two days. When questioned whether the product was genuine, one seller responded: “You can’t be sure.” Another provided a image of a supposed testing documentation. None inquired about weight, medical conditions or past usage.
Inside these communities, messages show dark colored parcels with Royal Mail labels, stating to include new batches. One communication stated: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, mixed at residence with purified liquid, or ready-to-use injectors typically priced at 160 pounds for 20mg. When asked how much time a injector should be used, sellers give conflicting answers varying between a several days to “depends on your body”.
A representative for the messaging service said it regularly moderated harmful material on its platform including content that promoted the “misuse of controlled medications”. The organization noted that it removed “millions of pieces of harmful content each day”.
“People are administering materials they cannot confirm. Even if the research behind retatrutide is valid, these digital products may not contain what they advertise,” said a pharmacy expert, the director of pharmaceutical services at a pharmacy service.
A medical professional of Asda Online Doctor connected the increase in demand to recent cost increases for approved slimming drugs such as Mounjaro. “With prices increasing, patients are turning to online platforms. But counterfeit treatments are highly dangerous. You can’t be certain what’s contained or whether the environment they were produced in was sterile,” she said.
Her team has already encountered individuals harmed by self-injection from unverified suppliers. “We recognize the disappointment, but purchasing from Telegram or WhatsApp is gambling with your health,” stated the doctor. “These materials could be contaminated or incorrectly dosed.”
A spokesperson from Eli Lilly stated the substance was in third stage clinical trials and had not been evaluated or authorized by any regulatory agency globally. “Therefore at this time no one can market [it] for human use,” they explained, noting that any item “misleadingly claiming itself as a Lilly experimental product not yet approved … may expose users to possibly significant health risks”.
