A shadow market for unlicensed slimming medications is being driven by social media fitness personalities and sellers on communication apps, based on recent findings.
Retatrutide, which remains in clinical trials, is being promoted by online personalities for its alleged fat-burning properties. Viewers are encouraged to message these profiles directly for supplier links, while also obtaining promotional offers.
Separately, a robust trade exists on Telegram, where groups with thousands of members share comparison photos, administration instructions and assertions of next-day UK delivery. Vendors market the substance there before redirecting customers to other platforms for transactions.
Retatrutide is an investigational injection created by American pharmaceutical company Eli Lilly. The drug targets three intestinal hormones – glucagon-like peptide-1, GIP and pancreatic hormone. Preliminary studies suggest it could help individuals reduce up to a quarter of their body weight. Referred to as the “triple G”, the drug is being hailed online as the next Ozempic.
Nevertheless, physicians and chemists have warned that the sale of what remains an unlicensed medication in the UK is a cause for concern and could result in individuals administering substances of unknown origin.
Several experts said the demand for the experimental drug could be connected to the increasing cost of approved weight loss products such as Mounjaro.
Marketing the unapproved drug on social media or messaging apps is illegal in the UK, as it is an unlicensed drug that must not be marketed or distributed for human use under the British medical regulations.
Several content creators try to sidestep the regulations by calling to the substance as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled drug, but advertising and supply can still violate pharmaceutical, advertising, and customer laws, risking fines, legal action or prison.
Based on TikTok, the service has removed problematic content and banned related hashtags and query recommendations. The organization said it was dedicated to keeping the platform safe and allocating resources in enhancing compliance measures.
Research also found groups with up to nine thousand participants marketing retatrutide using Telegram's integrated search feature, which functions like a online catalog. Entering “retatrutide” instantly displays channels with thousands of users, filled with photos of slimming results, positive reviews and detailed instructions for preparing or administering at home.
Within minutes of joining one group, a vendor posted contact information, where the majority of purchases occur. The seller provided an instruction manual and guaranteed shipping within two days. When asked whether the substance was authentic, one seller responded: “You can’t be sure.” Another shared a photo of a supposed testing documentation. Not one asked about body mass, health issues or previous experience.
Inside these groups, messages display dark colored 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 choose between powder vials, mixed at home with purified liquid, or pre-filled injectors usually sold at £160 for 20 milligrams. When questioned how long a injector should last, vendors give contradictory answers varying between a few weeks to “depends on your body”.
A representative for Telegram said it actively monitored dangerous content on its service including content that promoted the “misuse of controlled medications”. The organization added that it eliminated “millions of pieces of harmful content each day”.
“Individuals are administering materials they cannot confirm. Even if the research behind retatrutide is valid, these digital versions may not include what they advertise,” said a pharmacy expert, the head of pharmacy at Chemist4U.
Dr Crystal Wyllie of Asda Online Doctor linked the increase in demand to recent cost increases for authorized slimming medications such as Mounjaro. “With prices rising, individuals are turning to online platforms. But fake injections are highly dangerous. You cannot know what’s inside or whether the conditions they were produced in was clean,” she said.
Her staff has already seen individuals injured by personal administration from unverified suppliers. “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 improperly measured.”
A spokesperson from Eli Lilly said the substance was in third stage clinical trials and had not been evaluated or approved by any government authority anywhere in the world. “Therefore at this time no one can sell [it] for human use,” they said, adding that any product “falsely representing itself as a Lilly investigational product not yet approved … may subject patients to potentially significant medical dangers”.
