A shadow market for unapproved slimming drugs is propelled by social media fitness personalities and sellers on communication apps, according to new investigations.
The experimental drug, which remains in clinical trials, is being promoted by social media influencers for its alleged fat-burning properties. Followers are urged to message these profiles directly for supplier links, while also receiving promotional offers.
Separately, a robust trade exists on Telegram, where communities with thousands of participants share “before and after” photos, injection guides and claims of next-day UK delivery. Vendors market the substance there before redirecting buyers to WhatsApp for purchases.
Retatrutide is an experimental injectable created by American pharmaceutical company Eli Lilly. The drug targets three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Preliminary studies indicate it could help individuals reduce up to a quarter of their total weight. Nicknamed the “triple G”, the substance is being hailed online as the successor to Ozempic.
However, doctors and pharmacists have cautions that the sale of what is still an unapproved drug in the United Kingdom is worrisome and could lead to individuals administering products of uncertain source.
Some professionals said the demand for retatrutide could be linked to the rising price 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 unlicensed drug that cannot be promoted or distributed for human use under the Human Medicines Regulations 2012.
Several content creators attempt to sidestep the regulations by referring to the drug as a “research chemical” or citing it as “not for human consumption”. The substance is not a controlled drug, but promotion and supply can still violate pharmaceutical, marketing, and consumer regulations, potentially leading to penalties, legal action or prison.
Based on the social media company, the service has removed violative material and banned associated hashtags and query recommendations. The company stated it was dedicated to maintaining the platform secure and investing in enhancing compliance measures.
Investigations also found communities with up to nine thousand members marketing the experimental drug using the platform's integrated discovery tool, which operates like a online catalog. Typing “retatrutide” immediately displays groups with thousands of members, filled with photos of slimming results, glowing testimonials and detailed instructions for mixing or injecting at home.
Within moments of entering one group, a seller shared WhatsApp details, where the majority of transactions occur. The vendor sent an guidebook and promised delivery within two days. When asked whether the product was genuine, one seller responded: “You can’t be sure.” Another shared a photo of a alleged laboratory certificate. None inquired about body mass, medical conditions or previous experience.
Inside these communities, messages display dark colored parcels with postal service labels, claiming to contain new batches. One message read: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, mixed at residence with purified liquid, or pre-filled injectors usually sold at 160 pounds for 20 milligrams. When questioned how much time a pen should be used, sellers give conflicting responses ranging from a several days to “depends on your body”.
A representative for the messaging service stated it actively monitored harmful content on its platform including material that encouraged the “misuse of controlled medications”. The organization added that it removed “millions of pieces of harmful content each day”.
“Individuals are administering materials they cannot confirm. Although the science behind retatrutide is valid, these digital versions may not contain what they claim,” said Jason Murphy, the head of pharmaceutical services at Chemist4U.
A medical professional of Asda Online Doctor linked the increase in demand to current cost increases for authorized weight-loss medications such as Mounjaro. “With prices increasing, individuals are using social media. But fake injections are highly dangerous. You cannot know what’s contained or whether the conditions they were made in was sterile,” she said.
Her staff has already seen individuals harmed by personal administration from unconfirmed suppliers. “We recognize the disappointment, but buying from messaging apps or communication platforms is taking chances with your health,” said the doctor. “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 evaluated or authorized by any government authority globally. “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 expose patients to potentially significant health risks”.
