A shadow market for unlicensed weight-loss drugs is being driven by TikTok fitness influencers and vendors on messaging platforms, according to new investigations.
Retatrutide, which remains in clinical trials, is being promoted by online personalities for its alleged fat-burning properties. Viewers are encouraged to contact these profiles privately for source information, while also receiving promotional offers.
Separately, a robust market exists on messaging services, where groups with numerous of members share “before and after” photos, injection guides and assertions of next-day British shipping. Sellers market the substance there before directing buyers to WhatsApp for purchases.
This medication is an experimental injection developed by US drugmaker Eli Lilly. The treatment targets three gut hormones – GLP-1, GIP and pancreatic hormone. Early trials indicate it could assist patients lose up to a quarter of their body weight. Nicknamed the “triple G”, the drug is being promoted online as the next Ozempic.
Nevertheless, physicians and chemists have cautions that the sale of what is still an unapproved drug in the United Kingdom is worrisome and could result in users injecting products of unknown origin.
Several professionals stated the popularity for retatrutide could be connected to the rising cost of licensed slimming treatments such as Mounjaro.
Selling retatrutide on social media or Telegram is illegal in the United Kingdom, as it is an unlicensed drug that cannot be marketed or distributed for personal consumption under the Human Medicines Regulations 2012.
Some content creators try to sidestep the regulations by calling to the drug as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a controlled drug, but advertising and distribution can still violate pharmaceutical, marketing, and consumer laws, potentially leading to fines, legal action or prison.
Based on the social media company, the platform has removed problematic content and prohibited related keywords and query recommendations. The company stated it was dedicated to maintaining the platform secure and investing in enhancing compliance measures.
Research also discovered groups with up to 9,000 participants marketing retatrutide using the platform's integrated discovery tool, which functions like a public directory. Entering “retatrutide” instantly displays channels with numerous of members, populated with images of weight loss, positive reviews and detailed guides for mixing or administering at home.
Within minutes of joining one community, a vendor posted contact information, where the majority of purchases take place. The vendor sent an instruction manual and guaranteed delivery within two days. When questioned whether the product was genuine, one seller said: “You can’t be sure.” Another shared a image of a alleged laboratory certificate. None inquired about weight, medical conditions or previous experience.
Inside these groups, posts show dark colored parcels with postal service labels, claiming to include fresh supplies. One communication read: “It took eight of us to load them this morning.”
Buyers can choose between powder vials, prepared at home with sterile water, or pre-filled pens typically sold at £160 for 20mg. When questioned how much time a pen should last, vendors give conflicting responses varying between a few weeks to “depends on your body”.
A spokesperson for the messaging service said it regularly moderated harmful material on its service including material that promoted the “misuse of controlled medications”. The organization noted that it eliminated “millions of pieces of harmful content each day”.
“People are administering materials they can’t verify. Even if the research behind retatrutide is sound, these online versions may not contain what they claim,” said a pharmacy expert, the director of pharmaceutical services at a pharmacy service.
Dr Crystal Wyllie of Asda Online Doctor linked the surge in interest to recent price rises for approved weight-loss drugs such as Mounjaro. “With costs rising, patients are using online platforms. But counterfeit injections are extremely risky. You can’t be certain what’s contained or whether the conditions they were made in was sterile,” she said.
Her team has already encountered individuals injured by personal administration from unconfirmed sources. “We recognize the frustration, but purchasing from messaging apps or WhatsApp is taking chances 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 phase 3 research studies and had not been reviewed or approved by any government authority anywhere in the world. “Therefore at this point no one can market [it] for human use,” they said, adding that any product “misleadingly claiming itself as a company investigational substance not yet authorized … may subject users to possibly significant health risks”.
