An underground economy for unlicensed slimming drugs is propelled by TikTok fitness influencers and vendors on communication apps, based on new investigations.
Retatrutide, which is still in research studies, is being advertised by social media influencers for its supposed weight-reducing effects. Viewers are urged to message these profiles directly for source information, while also obtaining promotional offers.
Separately, a robust market exists on Telegram, where groups with thousands of participants share comparison images, administration instructions and claims of rapid British shipping. Vendors market the substance there before redirecting buyers to other platforms for transactions.
Retatrutide is an experimental injection created by US drugmaker Eli Lilly. The treatment targets three intestinal hormones – GLP-1, GIP and glucagon. Early trials suggest it could assist individuals lose up to a quarter of their body weight. Nicknamed the “triple G”, the drug is being promoted digitally as the successor to Ozempic.
Nevertheless, doctors and pharmacists have warned that the distribution of what is still an unapproved drug in the UK is a cause for concern and could result in users injecting substances of uncertain source.
Several professionals said the popularity for retatrutide could be linked to the increasing price of approved slimming treatments such as Mounjaro.
Selling retatrutide on TikTok or Telegram is prohibited in the United Kingdom, as it is an unlicensed medication that cannot be promoted or supplied for personal consumption under the Human Medicines Regulations 2012.
Several influencers try to circumvent the rules by referring to the drug as a “research chemical” or describing it as “not for human consumption”. The substance is not a restricted substance, but advertising and supply can still violate pharmaceutical, advertising, and consumer regulations, potentially leading to penalties, prosecution or imprisonment.
According to the social media company, the platform has taken down violative material and banned related hashtags and query recommendations. The organization stated it was dedicated to maintaining the platform safe and allocating resources in enhancing enforcement strategies.
Investigations also discovered communities with up to 9,000 participants marketing the experimental drug using the platform's built-in search feature, which functions like a online catalog. Typing “retatrutide” instantly brings up groups with thousands of members, populated with images of weight loss, positive reviews and detailed instructions for preparing or injecting at home.
Within moments of joining one community, a vendor shared WhatsApp details, where the majority of transactions take place. The seller provided an guidebook and promised shipping within 48 hours. When questioned whether the substance was authentic, one vendor said: “You can’t be sure.” Another provided a photo of a supposed laboratory certificate. Not one inquired about body mass, medical conditions or past usage.
Inside these groups, messages display black plastic packages with Royal Mail stickers, claiming to include new batches. One communication read: “It took eight of us to load them this morning.”
Buyers can choose between powder vials, mixed at home with sterile water, or ready-to-use injectors usually sold at 160 pounds for 20 milligrams. When asked how long a pen should be used, vendors give contradictory answers ranging from a several days to “depends on your body”.
A spokesperson for Telegram stated it regularly moderated dangerous material on its platform including content that encouraged the “misuse of controlled medications”. The company noted that it removed “millions of pieces of harmful content each day”.
“People are administering substances they cannot confirm. Although the research behind retatrutide is valid, these online versions may not include what they claim,” said Jason Murphy, the director of pharmacy at a pharmacy service.
Dr Crystal Wyllie of an online medical service linked the surge in demand to recent cost increases for approved slimming medications such as Mounjaro. “With costs rising, patients are using social media. But counterfeit treatments are highly dangerous. You can’t be certain what’s contained or whether the environment they were made in was clean,” she explained.
Her team has already encountered individuals injured by personal administration from unconfirmed suppliers. “We understand the disappointment, but buying from messaging apps or communication platforms is gambling with your well-being,” stated Wyllie. “These materials could be impure or improperly measured.”
A representative from the pharmaceutical company said the substance was in phase 3 clinical trials and had not been evaluated or authorized by any regulatory agency globally. “Consequently at this time no one can market [it] for personal consumption,” they said, noting that any item “falsely representing itself as a Lilly investigational substance not yet approved … may expose patients to possibly significant medical dangers”.
