A shadow market for unapproved slimming medications is propelled by TikTok fitness influencers and vendors on communication apps, based on recent findings.
The experimental drug, which is still in clinical trials, is being promoted by social media influencers for its alleged weight-reducing effects. Viewers are encouraged to message these profiles directly for supplier links, while also obtaining discount codes.
Separately, a robust trade exists on Telegram, where groups with thousands of members share comparison images, injection guides and claims of next-day British shipping. Vendors market the drug there before redirecting buyers to other platforms for purchases.
Retatrutide is an experimental injectable created by US drugmaker Eli Lilly. The treatment affects three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials indicate it could assist individuals reduce up to a quarter of their total weight. Nicknamed the “triple G”, the substance is being promoted digitally as the next Ozempic.
Nevertheless, physicians and pharmacists have cautions that the distribution of what remains an unapproved medication in the United Kingdom is worrisome and could lead to individuals injecting substances of uncertain source.
Several professionals stated the popularity for the experimental drug could be linked to the increasing price of approved weight loss products such as Mounjaro.
Marketing the unapproved drug on TikTok or messaging apps is prohibited in the United Kingdom, as it is an unlicensed drug that must not be marketed or supplied for human use under the Human Medicines Regulations 2012.
Several influencers try to sidestep the rules by calling to the substance as a “research chemical” or citing it as “not for human consumption”. The substance is not a restricted substance, but advertising and distribution can still breach medicines, advertising, and customer regulations, risking fines, prosecution or prison.
According to TikTok, the service has taken down problematic content and banned related hashtags and search suggestions. The organization stated it was dedicated to keeping the platform safe and investing in strengthening enforcement strategies.
Investigations also discovered groups with up to nine thousand participants marketing the experimental drug using Telegram's built-in search feature, which operates like a online catalog. Typing “retatrutide” instantly brings up groups with thousands of members, populated with images of slimming results, positive testimonials and detailed guides for preparing or injecting at residence.
Within minutes of entering one community, a seller posted contact information, where most purchases occur. The vendor provided an instruction manual and guaranteed shipping within 48 hours. When questioned whether the substance was genuine, one vendor said: “You can’t be sure.” Another provided a photo of a supposed testing documentation. Not one asked about body mass, health issues or previous experience.
Inside these communities, messages show dark colored parcels with postal service stickers, claiming to include fresh supplies. One message stated: “It took eight of us to load them this morning.”
Buyers can choose between dry substance containers, mixed at home with sterile water, or pre-filled injectors typically sold at £160 for 20mg. When questioned how long a injector should be used, sellers give contradictory answers ranging from a several days to “depends on your body”.
A spokesperson for Telegram said it regularly monitored harmful material on its service including content that promoted the “misuse of controlled medications”. The company added that it eliminated “millions of pieces of harmful content each day”.
“Individuals are injecting materials they cannot confirm. Even if the research behind this drug is sound, these digital versions may not include what they advertise,” said Jason Murphy, the head of pharmaceutical services at a pharmacy service.
Dr Crystal Wyllie of Asda Online Doctor linked the surge in interest to current price rises for approved weight-loss medications such as Mounjaro. “With prices increasing, patients are turning to social media. But counterfeit injections are extremely risky. You cannot know what’s contained or whether the conditions they were produced in was clean,” she explained.
Her team has already encountered individuals injured by self-injection from unconfirmed sources. “We understand the frustration, but purchasing from messaging apps or communication platforms is taking chances with your well-being,” said Wyllie. “These substances could be contaminated or incorrectly dosed.”
A representative from Eli Lilly said retatrutide was in third stage clinical trials and had not been reviewed or authorized by any government authority globally. “Therefore at this point no one can market [it] for human use,” they explained, noting that any item “misleadingly claiming itself as a company investigational product not yet authorized … may expose patients to possibly significant medical dangers”.
