An underground market for unlicensed slimming medications is propelled by TikTok fitness influencers and vendors on messaging platforms, according to recent findings.
The experimental drug, which is still in clinical trials, is being promoted by social media influencers for its alleged fat-burning properties. Viewers are urged to contact these accounts privately for source information, while also receiving promotional offers.
Separately, a robust trade exists on messaging services, where communities with thousands of members share comparison photos, administration instructions and assertions of next-day British shipping. Vendors market the drug there before redirecting customers to WhatsApp for purchases.
Retatrutide is an experimental injection developed by American pharmaceutical company Eli Lilly. The treatment affects three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Preliminary studies suggest it could assist patients reduce up to 25% of their body weight. Referred to as the “triple G”, the drug is being hailed digitally as the successor to Ozempic.
Nevertheless, physicians and pharmacists have cautions that the distribution of what is still an unlicensed drug in the UK is worrisome and could lead to users injecting substances of unknown origin.
Some experts stated the popularity for retatrutide could be connected to the rising cost of approved slimming treatments such as Mounjaro.
Selling retatrutide on social media or Telegram is prohibited in the UK, as it is an unapproved drug that must not be marketed or distributed for personal consumption under the Human Medicines Regulations 2012.
Some content creators try to sidestep the rules by calling to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a restricted drug, but promotion and distribution can still violate medicines, marketing, and customer regulations, potentially leading to fines, prosecution or prison.
Based on TikTok, the service has removed problematic material and prohibited related hashtags and query recommendations. The organization said it was dedicated to maintaining the service secure and investing in enhancing compliance measures.
Investigations also found communities with up to nine thousand members selling retatrutide using the platform's integrated discovery tool, which functions like a public directory. Entering “retatrutide” immediately displays channels with thousands of members, populated with photos of weight loss, positive testimonials and step-by-step guides for mixing or administering at residence.
After minutes of joining one group, a vendor posted WhatsApp details, where the majority of transactions take place. The seller provided an guidebook and promised shipping within 48 hours. When asked whether the product was genuine, one vendor said: “You can’t be sure.” Another provided a image of a supposed testing documentation. None inquired about weight, medical conditions or past usage.
Inside these communities, messages display black plastic packages with Royal Mail labels, claiming to include fresh supplies. One communication read: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, prepared at residence with sterile water, or pre-filled injectors typically sold at £160 for 20mg. When asked how long a pen should last, sellers give conflicting answers varying between a few weeks to “depends on your body”.
A representative for Telegram said it regularly monitored dangerous content on its platform including material that promoted the “misuse of controlled medications”. The company added that it eliminated “millions of pieces of harmful content each day”.
“People are injecting substances they can’t verify. Even if the science behind retatrutide is valid, these online versions may not include what they claim,” stated a pharmacy expert, the director of pharmaceutical services at Chemist4U.
A medical professional of Asda Online Doctor linked the surge in demand to current cost increases for approved slimming medications such as Mounjaro. “With prices rising, individuals are using social media. But fake treatments are highly dangerous. You cannot know what’s inside or whether the environment they were produced in was sterile,” she said.
Her team has previously encountered patients injured by self-injection from unverified suppliers. “We recognize the disappointment, but buying from messaging apps or WhatsApp is taking chances with your well-being,” said Wyllie. “These substances could be impure or incorrectly dosed.”
A representative from the pharmaceutical company stated retatrutide was in phase 3 research studies and had not been reviewed or approved by any government authority globally. “Consequently at this point no one can market [it] for personal consumption,” they said, noting that any item “misleadingly claiming itself as a Lilly investigational product not yet approved … may expose users to possibly significant health risks”.
