An underground economy for unlicensed slimming drugs is propelled by TikTok fitness influencers and vendors on messaging platforms, based on recent findings.
Retatrutide, which is still in clinical trials, is being promoted by online personalities for its supposed fat-burning effects. Viewers are encouraged to message these accounts privately for supplier links, while also receiving promotional offers.
Separately, a flourishing market exists on messaging services, where groups with numerous of members share comparison images, injection guides and claims of next-day British shipping. Vendors promote the substance there before redirecting buyers to WhatsApp for purchases.
Retatrutide is an investigational injection developed by US drugmaker Eli Lilly. The drug targets three intestinal hormones – GLP-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Preliminary studies indicate it could assist patients reduce up to a quarter of their body weight. Referred to as the “triple G”, the substance is being hailed online as the next Ozempic.
Nevertheless, doctors and pharmacists have warned that the distribution of what is still an unlicensed drug in the United Kingdom is a cause for concern and could result in individuals administering products of unknown origin.
Several professionals stated the demand for the experimental drug could be linked to the rising cost of approved slimming products such as Mounjaro.
Marketing the unapproved drug on social media or Telegram is illegal in the UK, as it is an unapproved drug that must not be promoted or supplied for human use under the British medical regulations.
Some 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 restricted drug, but advertising and distribution can still violate pharmaceutical, advertising, and consumer regulations, potentially leading to fines, prosecution or imprisonment.
Based on the social media company, the platform has taken down violative material and banned related hashtags and query recommendations. The organization said it was dedicated to keeping the platform secure and investing in strengthening enforcement strategies.
Investigations also discovered groups with up to nine thousand participants selling retatrutide using Telegram's integrated search feature, which functions like a public directory. Typing “retatrutide” immediately displays groups with numerous of users, populated with photos of weight loss, positive reviews and detailed guides for mixing or injecting at home.
Within minutes of joining one group, a seller posted WhatsApp details, where most purchases occur. The seller provided an guidebook and guaranteed delivery within 48 hours. When questioned whether the product was authentic, one vendor said: “You can’t be sure.” Another provided a photo of a supposed laboratory certificate. Not one asked about body mass, health issues or past usage.
Within these communities, messages display black plastic parcels with Royal Mail labels, claiming to include new batches. One message stated: “It took eight of us to load them this morning.”
Customers can select between powder vials, prepared at home with purified liquid, or pre-filled injectors typically priced at 160 pounds for 20 milligrams. When questioned how long a injector should be used, vendors give conflicting answers ranging from a several days to “depends on your body”.
A spokesperson for Telegram stated it regularly moderated harmful material on its service including material that promoted the “misuse of controlled medications”. The company noted that it removed “millions of pieces of harmful content each day”.
“Individuals are administering materials they cannot confirm. Although the science behind retatrutide is sound, these digital products may not include what they advertise,” stated a pharmacy expert, the head of pharmacy at Chemist4U.
Dr Crystal Wyllie of an online medical service connected the surge in interest to recent price rises for approved weight-loss medications such as Mounjaro. “With costs rising, individuals are turning to social media. But fake injections are highly risky. You can’t be certain what’s inside or whether the environment they were produced in was sterile,” she explained.
Her team has already seen patients injured by self-injection from unverified suppliers. “We recognize the frustration, but purchasing from messaging apps or WhatsApp is gambling with your well-being,” said the doctor. “These substances could be impure or improperly measured.”
A spokesperson from the pharmaceutical company stated the substance was in third stage research studies and had not been evaluated or authorized by any regulatory agency globally. “Therefore at this time no one can sell [it] for personal consumption,” they said, adding that any product “falsely representing itself as a company investigational product not yet approved … may expose patients to potentially significant medical dangers”.
