A shadow economy for unlicensed weight-loss drugs is propelled by TikTok fitness influencers and vendors on messaging platforms, according to new investigations.
The experimental drug, which remains in research studies, is being advertised by social media influencers for its supposed fat-burning effects. Viewers are urged to message these profiles directly for supplier links, while also obtaining discount codes.
Separately, a flourishing market exists on Telegram, where groups with thousands of members share comparison images, administration instructions and claims of rapid UK delivery. Vendors market the drug there before directing customers to WhatsApp for purchases.
Retatrutide is an experimental injectable developed by US drugmaker Eli Lilly. The drug targets three intestinal hormones – GLP-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials indicate it could assist patients lose up to 25% of their total weight. Nicknamed the “triple G”, the drug is being promoted digitally as the successor to Ozempic.
However, physicians and chemists have cautions that the distribution of what is still an unlicensed drug in the UK is a cause for concern and could lead to users administering products of unknown origin.
Some experts stated the demand for retatrutide could be linked to the increasing price of licensed weight loss treatments such as Mounjaro.
Marketing the unapproved drug on social media or messaging apps is prohibited in the UK, as it is an unlicensed drug that cannot be marketed or distributed for human use under the British medical regulations.
Several content creators try to sidestep 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 promotion and distribution can still breach medicines, advertising, and customer regulations, risking penalties, legal action or imprisonment.
Based on TikTok, the platform has removed violative material and banned associated hashtags and query recommendations. The organization said it was dedicated to keeping the service safe and allocating resources in strengthening enforcement strategies.
Investigations also found groups with up to nine thousand participants marketing the experimental drug using Telegram's built-in discovery tool, which functions like a public directory. Entering “retatrutide” instantly displays groups with numerous of users, populated with photos of slimming results, glowing reviews and step-by-step guides for mixing or injecting at residence.
After moments of joining one community, a vendor shared contact information, where most transactions occur. The vendor provided an guidebook and promised shipping within two days. When questioned whether the substance was genuine, one seller said: “You can’t be sure.” Another shared a photo of a alleged testing documentation. None inquired about body mass, medical conditions or past usage.
Inside these groups, posts show dark colored parcels with Royal Mail labels, claiming to include fresh supplies. One message read: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, mixed at residence with sterile water, or ready-to-use injectors usually priced at £160 for 20mg. When asked how much time a injector should be used, sellers give conflicting answers ranging from a several days to “depends on your body”.
A spokesperson for the messaging service said it actively monitored dangerous material on its service including material that promoted the “misuse of controlled medications”. The company noted that it removed “millions of pieces of harmful content each day”.
“People are administering materials they cannot confirm. Although the research behind this drug is valid, these online versions may not include what they claim,” stated a pharmacy expert, the director of pharmacy at Chemist4U.
A medical professional of an online medical service linked the surge in demand to current cost increases for approved weight-loss medications such as Mounjaro. “With costs rising, individuals are turning to online platforms. But fake injections are extremely risky. You cannot know what’s inside or whether the environment they were made in was sterile,” she said.
Her team has previously seen individuals harmed by self-injection from unverified suppliers. “We understand the frustration, but buying from messaging apps or communication platforms is gambling with your health,” said the doctor. “These substances could be impure or incorrectly dosed.”
A spokesperson from Eli Lilly stated retatrutide was in third stage clinical trials and had not been reviewed or authorized by any government authority anywhere in the world. “Therefore at this time no one can sell [it] for human use,” they explained, adding that any item “falsely representing itself as a company investigational product not yet approved … may subject patients to potentially serious medical dangers”.
