A shadow economy for unapproved slimming drugs is propelled by TikTok fitness influencers and vendors on communication apps, based on recent findings.
Retatrutide, which is still in research studies, is being promoted by online personalities for its supposed fat-burning properties. Followers are urged to message these accounts privately for supplier links, while also receiving promotional offers.
Separately, a robust market exists on messaging services, where communities with numerous of members share “before and after” images, administration instructions and assertions of rapid UK delivery. Vendors promote the drug there before redirecting customers to WhatsApp for purchases.
Retatrutide is an experimental injection developed by American pharmaceutical company Eli Lilly. The drug targets three intestinal hormones – glucagon-like peptide-1, GIP and glucagon. Early trials suggest it could assist patients reduce up to a quarter of their body weight. Nicknamed the “triple G”, the drug is being promoted digitally as the next Ozempic.
Nevertheless, doctors and pharmacists have warned that the distribution of what is still an unapproved medication in the United Kingdom is a cause for concern and could result in individuals injecting substances of unknown origin.
Some professionals said the popularity for retatrutide could be linked to the increasing cost of approved weight loss treatments such as Mounjaro.
Marketing the unapproved drug on TikTok or Telegram is illegal in the United Kingdom, as it is an unlicensed drug that must not be promoted or distributed for personal consumption under the British medical regulations.
Several content creators attempt to sidestep the regulations by referring to the substance as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled drug, but advertising and distribution can still breach medicines, marketing, and customer laws, potentially leading to penalties, legal action or imprisonment.
Based on TikTok, the service has removed problematic material and prohibited associated hashtags and search suggestions. The company said it was committed to maintaining the platform safe and allocating resources in strengthening enforcement strategies.
Research also found groups with up to 9,000 members selling the experimental drug using the platform's built-in search feature, which functions like a public directory. Typing “retatrutide” immediately brings up groups with thousands of users, populated with photos of slimming results, positive testimonials and detailed guides for preparing or injecting at home.
Within moments of entering one community, a vendor posted WhatsApp details, where the majority of purchases occur. The seller provided an guidebook and promised delivery within 48 hours. When asked whether the substance was genuine, one vendor said: “You can’t be sure.” Another provided a image of a supposed laboratory certificate. Not one inquired about weight, medical conditions or previous experience.
Inside these groups, posts display black plastic parcels with postal service labels, claiming to include new batches. One communication stated: “It took eight of us to load them this morning.”
Buyers can select between dry substance containers, prepared at residence with purified liquid, or pre-filled injectors typically sold at 160 pounds for 20mg. When questioned how long a injector should last, sellers give conflicting responses varying between a several days to “depends on your body”.
A representative for Telegram stated it actively moderated harmful content on its platform including material that promoted the “misuse of controlled medications”. The organization noted that it removed “millions of pieces of harmful content each day”.
“Individuals are injecting materials they cannot confirm. Even if the research behind this drug is valid, these digital products may not contain what they advertise,” said Jason Murphy, the director of pharmaceutical services at a pharmacy service.
Dr Crystal Wyllie of Asda Online Doctor linked the surge in demand to recent cost increases for approved slimming drugs such as Mounjaro. “With prices rising, individuals are turning to social media. But counterfeit injections are highly risky. You cannot know what’s inside or whether the environment they were produced in was sterile,” she said.
Her staff has previously seen patients injured by personal administration from unverified sources. “We recognize the frustration, but purchasing from messaging apps or communication platforms is taking chances with your health,” stated Wyllie. “These substances could be impure or incorrectly dosed.”
A spokesperson from the pharmaceutical company stated the substance was in third stage research studies and had not been reviewed or approved by any government authority anywhere in the world. “Consequently at this point no one can sell [it] for personal consumption,” they explained, noting that any item “misleadingly claiming itself as a Lilly experimental substance not yet authorized … may subject patients to possibly significant medical dangers”.
