An underground market for unlicensed weight-loss medications is being driven by TikTok fitness influencers and vendors on messaging platforms, according to recent findings.
The experimental drug, which remains in clinical trials, is being promoted by social media influencers for its supposed fat-burning properties. Followers are encouraged to message these profiles directly for supplier links, while also obtaining promotional offers.
Additionally, a flourishing market exists on Telegram, where groups with numerous of members share “before and after” photos, administration instructions and claims of next-day UK delivery. Vendors promote the substance there before directing buyers to WhatsApp for transactions.
This medication is an experimental injectable created by American pharmaceutical company Eli Lilly. The treatment targets three intestinal hormones – GLP-1, GIP and glucagon. Early trials suggest it could assist patients lose up to a quarter of their total weight. Nicknamed the “triple G”, the drug is being promoted online as the successor to Ozempic.
Nevertheless, doctors and chemists have cautions that the distribution of what remains an unapproved drug in the United Kingdom is worrisome and could lead to users administering substances of uncertain source.
Some professionals said the demand for the experimental drug could be connected to the rising cost of approved weight loss products such as Mounjaro.
Marketing retatrutide on social media or messaging apps is prohibited in the United Kingdom, as it is an unapproved drug that cannot be marketed or supplied for human use under the Human Medicines Regulations 2012.
Several influencers attempt to circumvent the regulations by calling to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled drug, but advertising and supply can still violate medicines, advertising, and customer regulations, risking penalties, prosecution or prison.
Based on the social media company, the platform has taken down problematic material and prohibited related hashtags and query recommendations. The company stated it was committed to maintaining the platform secure and allocating resources in enhancing enforcement strategies.
Investigations also found groups with up to 9,000 members selling retatrutide using the platform's integrated search feature, which functions like a online catalog. Typing “retatrutide” immediately brings up groups with thousands of users, populated with images of weight loss, glowing reviews and detailed instructions for mixing or injecting at residence.
Within minutes of entering one community, a vendor shared WhatsApp details, where the majority of transactions occur. The seller provided an guidebook and promised shipping within 48 hours. When asked whether the product was genuine, one seller said: “You can’t be sure.” Another provided a photo of a alleged laboratory certificate. None inquired about body mass, medical conditions or past usage.
Inside these communities, messages display black plastic packages with postal service stickers, claiming to include new batches. One message stated: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, prepared at residence with purified liquid, or pre-filled injectors typically sold at £160 for 20 milligrams. When asked how long a injector should last, vendors give conflicting answers ranging from a several days to “depends on your body”.
A spokesperson for Telegram said it regularly moderated harmful material on its service including material that promoted the “misuse of controlled medications”. The organization added that it removed “millions of pieces of harmful content each day”.
“Individuals are administering materials they can’t verify. Even if the science behind retatrutide is sound, these online products may not include what they claim,” said Jason Murphy, the head of pharmacy at a pharmacy service.
A medical professional of an online medical service linked the increase in interest to recent cost increases for authorized slimming drugs such as Mounjaro. “With prices rising, patients are using online platforms. But counterfeit injections are highly dangerous. You cannot know what’s inside or whether the environment they were produced in was clean,” she explained.
Her staff has already encountered individuals harmed by self-injection from unverified sources. “We recognize the frustration, but purchasing from Telegram or communication platforms is taking chances with your well-being,” stated Wyllie. “These materials could be impure or incorrectly dosed.”
A spokesperson from Eli Lilly said retatrutide was in phase 3 clinical trials and had not been reviewed or authorized by any regulatory agency anywhere in the world. “Consequently at this point no one can market [it] for personal consumption,” they explained, adding that any item “misleadingly claiming itself as a Lilly investigational substance not yet approved … may subject patients to potentially significant health risks”.
