An underground economy for unapproved slimming drugs is propelled by TikTok fitness influencers and sellers on messaging platforms, according to recent findings.
Retatrutide, which is still in clinical trials, is being promoted by social media influencers for its supposed fat-burning properties. Followers are urged to contact these profiles directly for supplier links, while also receiving discount codes.
Additionally, a flourishing trade exists on Telegram, where communities with thousands of participants share “before and after” images, injection guides and assertions of rapid UK delivery. Sellers promote the substance there before directing customers to other platforms for transactions.
Retatrutide is an investigational injectable created by US drugmaker Eli Lilly. The drug targets three intestinal hormones – GLP-1, GIP and glucagon. Preliminary studies indicate it could help individuals reduce up to a quarter of their total weight. Nicknamed the “triple G”, the substance is being promoted online as the successor to Ozempic.
Nevertheless, doctors and chemists have warned that the sale of what remains an unlicensed drug in the United Kingdom is a cause for concern and could result in users injecting substances of unknown origin.
Several professionals said the demand for retatrutide could be linked to the increasing price of approved weight loss products such as Mounjaro.
Marketing the unapproved drug on social media or messaging apps is illegal in the United Kingdom, as it is an unlicensed medication that must not be promoted or supplied for personal consumption under the Human Medicines Regulations 2012.
Several content creators attempt to circumvent the rules by calling to the substance as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled substance, but advertising and supply can still violate pharmaceutical, advertising, and customer regulations, potentially leading to fines, legal action or prison.
According to the social media company, the platform has taken down violative content and prohibited related hashtags and query recommendations. The company said it was dedicated to maintaining the service secure and allocating resources in strengthening compliance measures.
Research also found groups with up to 9,000 participants marketing the experimental drug using Telegram's integrated search feature, which functions like a public directory. Entering “retatrutide” instantly displays groups with numerous of members, filled with photos of weight loss, glowing reviews and detailed instructions for preparing or administering at residence.
Within minutes of joining one community, a vendor shared WhatsApp details, where most purchases take place. The seller sent an instruction manual and guaranteed delivery within 48 hours. When asked whether the product was genuine, one seller said: “You can’t be sure.” Another shared a image of a supposed laboratory certificate. Not one inquired about body mass, health issues or past usage.
Within these groups, posts display black plastic parcels with Royal Mail labels, stating to contain new batches. One message stated: “It took eight of us to load them this morning.”
Buyers can choose between powder vials, mixed at home with sterile water, or ready-to-use injectors typically priced at 160 pounds for 20 milligrams. When asked how long a pen should last, sellers give conflicting responses ranging from a few weeks to “depends on your body”.
A representative for the messaging service stated it regularly monitored harmful material on its platform including content that encouraged the “misuse of controlled medications”. The company noted that it eliminated “millions of pieces of harmful content each day”.
“Individuals are administering materials they cannot confirm. Even if the research behind this drug is valid, these digital products may not contain what they advertise,” said a pharmacy expert, the director of pharmacy at Chemist4U.
Dr Crystal Wyllie of Asda Online Doctor linked the surge in demand to recent cost increases for approved slimming drugs such as Mounjaro. “With costs increasing, patients are using social media. But counterfeit injections are highly dangerous. You can’t be certain what’s contained or whether the environment they were made in was sterile,” she said.
Her team has already encountered patients injured by self-injection from unconfirmed suppliers. “We understand the disappointment, but purchasing from Telegram or WhatsApp is taking chances with your well-being,” said the doctor. “These materials could be impure or incorrectly dosed.”
A spokesperson from Eli Lilly stated retatrutide was in phase 3 research studies and had not been evaluated or approved by any government authority anywhere in the world. “Consequently at this point no one can market [it] for personal consumption,” they explained, noting that any product “misleadingly claiming itself as a company investigational product not yet approved … may subject users to potentially serious health risks”.
