A shadow market for unapproved slimming medications is being driven by TikTok fitness influencers and sellers on communication apps, based on recent findings.
The experimental drug, which is still in research studies, is being promoted by online personalities for its supposed fat-burning effects. Followers are urged to message these accounts privately for source information, while also receiving discount codes.
Separately, a flourishing trade exists on Telegram, where groups with thousands of participants share “before and after” images, administration instructions and assertions of rapid UK delivery. Sellers promote the drug there before directing customers to other platforms for transactions.
Retatrutide is an experimental injection developed by American pharmaceutical company Eli Lilly. The drug affects three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials indicate it could assist patients lose up to a quarter of their total weight. Nicknamed the “triple G”, the drug is being hailed digitally as the successor to Ozempic.
Nevertheless, doctors and pharmacists have cautions that the sale of what remains an unlicensed medication in the United Kingdom is a cause for concern and could result in users injecting products of uncertain source.
Several professionals stated the popularity for the experimental drug could be connected to the increasing price of approved weight loss treatments such as Mounjaro.
Marketing retatrutide on social media or Telegram is illegal in the United Kingdom, as it is an unlicensed medication that must not be marketed or supplied for human use under the Human Medicines Regulations 2012.
Some influencers try to sidestep the rules by calling to the drug as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a controlled drug, but promotion and supply can still violate medicines, marketing, and customer regulations, potentially leading to fines, prosecution or imprisonment.
Based on the social media company, the platform has removed problematic content and banned related hashtags and query recommendations. The company stated it was committed to maintaining the platform secure and allocating resources in enhancing compliance measures.
Research also discovered communities with up to 9,000 participants selling retatrutide using the platform's built-in discovery tool, which operates like a online catalog. Typing “retatrutide” immediately brings up channels with numerous of users, filled with photos of slimming results, positive reviews and detailed instructions for mixing or administering at home.
After moments of joining one community, a seller posted contact information, where most purchases occur. The seller provided an instruction manual and guaranteed delivery within 48 hours. When questioned whether the substance was authentic, one vendor said: “You can’t be sure.” Another provided a image of a supposed testing documentation. None inquired about body mass, health issues or previous experience.
Inside these communities, messages display dark colored packages with postal service labels, stating to contain fresh supplies. One communication stated: “It took eight of us to load them this morning.”
Buyers can select between dry substance containers, mixed at residence with sterile water, or ready-to-use injectors usually priced at 160 pounds for 20 milligrams. When questioned how much time a injector should last, vendors give contradictory answers ranging from a few weeks to “depends on your body”.
A spokesperson for the messaging service said it actively monitored dangerous content on its platform including material that encouraged the “misuse of controlled medications”. The organization added that it removed “millions of pieces of harmful content each day”.
“People are injecting materials they can’t verify. Even if the science behind this drug is sound, these digital products may not contain what they advertise,” said Jason Murphy, the director of pharmacy at a pharmacy service.
Dr Crystal Wyllie of Asda Online Doctor linked the increase in interest to current cost increases for authorized weight-loss medications such as Mounjaro. “With prices rising, individuals are using online platforms. But counterfeit injections are extremely dangerous. You can’t be certain what’s contained or whether the conditions they were made in was sterile,” she explained.
Her staff has previously seen individuals injured by personal administration from unconfirmed suppliers. “We understand the frustration, but buying from messaging apps or communication platforms is gambling with your health,” said the doctor. “These materials could be impure or improperly measured.”
A spokesperson from Eli Lilly stated retatrutide was in phase 3 clinical trials and had not been evaluated or authorized by any government authority globally. “Consequently at this time no one can market [it] for human use,” they said, adding that any product “falsely representing itself as a Lilly investigational substance not yet authorized … may expose users to possibly serious medical dangers”.
