An underground market for unapproved slimming drugs is being driven by TikTok fitness influencers and vendors on communication apps, based on recent findings.
Retatrutide, which remains in clinical trials, is being advertised by online personalities for its alleged weight-reducing properties. Viewers are encouraged to message these accounts directly for supplier links, while also receiving discount codes.
Additionally, a robust market exists on Telegram, where groups with thousands of participants share comparison photos, administration instructions and assertions of rapid UK delivery. Sellers promote the drug there before redirecting buyers to other platforms for transactions.
Retatrutide is an experimental injection created by US drugmaker Eli Lilly. The treatment targets three gut hormones – glucagon-like peptide-1, GIP and glucagon. Early trials suggest it could assist individuals reduce up to a quarter of their total weight. Referred to as the “triple G”, the drug is being hailed digitally as the next Ozempic.
Nevertheless, doctors and pharmacists have cautions that the sale of what is still an unlicensed medication in the United Kingdom is worrisome and could lead to individuals administering products of uncertain source.
Some professionals stated 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 TikTok or messaging apps is illegal in the UK, as it is an unapproved medication that cannot be promoted or distributed for human use under the Human Medicines Regulations 2012.
Several content creators try to circumvent the regulations by calling to the drug as a “research chemical” or describing it as “not for human consumption”. The substance is not a restricted drug, but promotion and supply can still violate medicines, marketing, and customer regulations, risking penalties, prosecution or prison.
According to the social media company, the service has taken down problematic content and banned associated keywords and search suggestions. The organization said it was committed to maintaining the platform secure and allocating resources in strengthening enforcement strategies.
Research also discovered communities with up to 9,000 members selling retatrutide using the platform's integrated search feature, which functions like a online catalog. Typing “retatrutide” instantly brings up channels with numerous of users, filled with images of weight loss, positive testimonials and detailed instructions for mixing or injecting at residence.
Within minutes of joining one group, a seller shared WhatsApp details, where most purchases occur. The vendor sent an guidebook and promised delivery within two days. When asked whether the product was genuine, one vendor said: “You can’t be sure.” Another shared a image of a supposed testing documentation. None asked about weight, medical conditions or previous experience.
Inside these groups, messages display black plastic parcels with Royal Mail stickers, stating to include fresh supplies. One message read: “It took eight of us to load them this morning.”
Buyers can choose between powder vials, prepared at home with sterile water, or ready-to-use injectors usually sold at £160 for 20 milligrams. When questioned how long a pen should be used, sellers give contradictory answers varying between a several days to “depends on your body”.
A spokesperson for the messaging service stated it actively monitored dangerous 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”.
“People are administering materials they can’t verify. Although the science behind retatrutide is valid, these online versions may not include what they claim,” said Jason Murphy, the director of pharmaceutical services at Chemist4U.
Dr Crystal Wyllie of Asda Online Doctor linked the surge in interest to recent cost increases for approved slimming drugs such as Mounjaro. “With prices rising, individuals are turning to social media. But fake injections are highly dangerous. You cannot know what’s inside or whether the conditions they were produced in was sterile,” she explained.
Her team has previously seen patients injured by personal administration from unconfirmed sources. “We recognize the frustration, but purchasing from messaging apps or WhatsApp is gambling with your well-being,” said the doctor. “These materials could be impure or incorrectly dosed.”
A spokesperson from the pharmaceutical company stated retatrutide was in third stage research studies and had not been evaluated or authorized by any government authority globally. “Therefore at this time no one can market [it] for human use,” they said, adding that any product “misleadingly claiming itself as a Lilly investigational product not yet approved … may subject users to possibly significant health risks”.
