A shadow market for unlicensed weight-loss drugs is being driven by TikTok fitness influencers and vendors on communication apps, based on new investigations.
Retatrutide, which remains in clinical trials, is being advertised by online personalities for its alleged weight-reducing effects. Viewers are encouraged to message these profiles privately for supplier links, while also receiving promotional offers.
Separately, a robust market exists on messaging services, where groups with thousands of members share comparison photos, administration instructions and claims of next-day UK delivery. Sellers market the drug there before directing customers to other platforms for transactions.
Retatrutide is an experimental injection created by US drugmaker Eli Lilly. The treatment affects three gut hormones – GLP-1, GIP and pancreatic hormone. Early trials indicate it could assist patients lose up to a quarter of their total weight. Nicknamed the “triple G”, the substance is being hailed digitally as the next Ozempic.
Nevertheless, doctors and chemists have cautions that the distribution of what remains an unlicensed medication in the United Kingdom is worrisome and could result in individuals injecting substances of uncertain source.
Some experts said the demand for retatrutide could be connected to the rising price of approved weight loss products such as Mounjaro.
Selling retatrutide on social media or messaging apps is illegal in the United Kingdom, as it is an unapproved drug that must not be marketed or distributed for personal consumption under the British medical regulations.
Several content creators try to sidestep the rules by referring to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled substance, but promotion and supply can still violate medicines, advertising, and consumer regulations, potentially leading to penalties, legal action or imprisonment.
Based on the social media company, the service has taken down violative material and banned related keywords and query recommendations. The company said it was committed to maintaining the service safe and allocating resources in strengthening enforcement strategies.
Investigations also found communities with up to 9,000 members selling retatrutide using the platform's integrated discovery tool, which functions like a online catalog. Entering “retatrutide” instantly displays groups with thousands of members, filled with images of weight loss, positive testimonials and detailed instructions for preparing or administering at residence.
Within minutes of entering one group, a vendor posted contact information, where most transactions take place. The seller provided an instruction manual and guaranteed delivery within 48 hours. When asked whether the substance was genuine, one seller responded: “You can’t be sure.” Another shared a image of a supposed testing documentation. None inquired about body mass, health issues or previous experience.
Inside these communities, posts display black plastic packages with postal service stickers, stating to include fresh supplies. One communication stated: “It took eight of us to load them this morning.”
Buyers can select between dry substance containers, mixed at home with purified liquid, or pre-filled injectors usually priced at 160 pounds for 20 milligrams. When questioned how long a injector should last, sellers give conflicting responses varying between a several days to “depends on your body”.
A spokesperson for Telegram stated it regularly monitored harmful material on its platform 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. Although the science behind retatrutide is valid, these digital versions may not include what they claim,” said a pharmacy expert, the director of pharmacy at a pharmacy service.
Dr Crystal Wyllie of an online medical service linked the increase in interest to current price rises for authorized slimming drugs such as Mounjaro. “With costs increasing, individuals are using social media. But fake injections are highly risky. You cannot know what’s inside or whether the conditions they were produced in was clean,” she said.
Her team has previously seen individuals injured by personal administration from unconfirmed sources. “We understand the frustration, but purchasing from Telegram or communication platforms is gambling with your health,” stated the doctor. “These substances could be contaminated or improperly measured.”
A spokesperson from Eli Lilly said retatrutide was in phase 3 research studies and had not been evaluated or authorized by any government authority anywhere in the world. “Consequently at this time no one can market [it] for personal consumption,” they said, adding that any product “falsely representing itself as a Lilly experimental substance not yet authorized … may expose users to possibly serious medical dangers”.
