An underground market for unapproved slimming drugs is being driven by social media fitness personalities and vendors on communication apps, based on new investigations.
Retatrutide, which is still in clinical trials, is being advertised by social media influencers for its supposed fat-burning properties. Viewers are urged to message these profiles directly for supplier links, while also obtaining promotional offers.
Separately, a flourishing trade exists on Telegram, where groups with thousands of members share comparison images, administration instructions and claims of rapid UK delivery. Sellers market the substance there before redirecting customers to WhatsApp for transactions.
Retatrutide is an investigational injectable created by US drugmaker Eli Lilly. The treatment targets three intestinal hormones – glucagon-like peptide-1, GIP and glucagon. Early trials indicate it could assist individuals reduce up to 25% of their total weight. Nicknamed the “triple G”, the substance is being promoted digitally as the successor to Ozempic.
However, doctors and chemists have warned that the distribution of what is still an unapproved drug in the United Kingdom is a cause for concern and could lead to individuals injecting substances of uncertain source.
Several professionals stated the demand for the experimental drug could be connected to the rising price of approved weight loss products such as Mounjaro.
Selling retatrutide on social media or messaging apps is illegal 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.
Several influencers attempt to circumvent the regulations by referring to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a restricted substance, but advertising and distribution can still breach pharmaceutical, advertising, and customer laws, potentially leading to penalties, legal action or imprisonment.
According to TikTok, the service has taken down violative content and prohibited related keywords and query recommendations. The organization stated it was committed to keeping the service safe and investing in enhancing enforcement strategies.
Investigations also found communities with up to 9,000 members selling the experimental drug using the platform's built-in search feature, which operates like a online catalog. Entering “retatrutide” instantly displays groups with thousands of users, populated with photos of slimming results, glowing reviews and step-by-step guides for mixing or administering at home.
After minutes of joining one community, a seller posted contact information, where most transactions take place. The seller provided an guidebook and guaranteed shipping within two days. When questioned whether the product was genuine, one vendor responded: “You can’t be sure.” Another provided a photo of a alleged testing documentation. Not one inquired about body mass, health issues or past usage.
Inside these groups, messages display dark colored packages with postal service stickers, claiming to include new batches. One communication 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 pens typically priced at 160 pounds for 20mg. When asked how long a pen should last, sellers give contradictory responses varying between a several days to “depends on your body”.
A representative for Telegram said it actively monitored harmful material on its service including material that encouraged the “misuse of controlled medications”. The organization noted that it removed “millions of pieces of harmful content each day”.
“Individuals are injecting substances they cannot confirm. Even if the science behind this drug is valid, these online products may not contain what they claim,” said Jason Murphy, the director of pharmacy at a pharmacy service.
A medical professional of Asda Online Doctor linked the increase in interest to current price rises for authorized weight-loss drugs such as Mounjaro. “With costs rising, individuals are using online platforms. But counterfeit injections are extremely dangerous. You can’t be certain what’s inside or whether the environment they were produced in was clean,” she said.
Her team has already encountered patients harmed by self-injection from unverified sources. “We recognize the frustration, but buying from Telegram or WhatsApp is taking chances with your well-being,” said Wyllie. “These materials could be impure or incorrectly dosed.”
A representative from Eli Lilly said the substance was in third stage research studies and had not been reviewed or approved by any regulatory agency anywhere in the world. “Therefore at this point no one can market [it] for human use,” they explained, adding that any item “misleadingly claiming itself as a company investigational product not yet approved … may expose users to potentially serious health risks”.
