An underground market for unlicensed weight-loss medications is being driven by social media fitness personalities and vendors on communication apps, according to new investigations.
The experimental drug, which remains in research studies, is being advertised by online personalities for its alleged weight-reducing properties. Viewers are urged to message these profiles privately for supplier links, while also obtaining promotional offers.
Separately, a robust trade exists on Telegram, where communities with numerous of members share “before and after” images, administration instructions and claims of next-day British shipping. Vendors promote the drug there before directing buyers to other platforms for purchases.
Retatrutide is an investigational injectable created by US drugmaker Eli Lilly. The drug targets three intestinal hormones – GLP-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials indicate it could help individuals lose up to a quarter of their body weight. Nicknamed the “triple G”, the drug is being promoted digitally as the successor to Ozempic.
However, doctors and chemists have cautions that the sale of what remains an unlicensed medication in the UK is worrisome and could result in individuals injecting products of uncertain source.
Several experts said the popularity for the experimental drug could be linked to the rising price of licensed slimming treatments such as Mounjaro.
Marketing retatrutide on social media or messaging apps is illegal in the UK, as it is an unapproved drug that cannot be promoted or supplied for personal consumption under the Human Medicines Regulations 2012.
Some content creators attempt to circumvent the rules by calling to the substance as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled drug, but promotion and distribution can still violate medicines, marketing, and customer laws, potentially leading to fines, legal action or imprisonment.
According to the social media company, the service has taken down violative material and prohibited related keywords and search suggestions. The company said it was dedicated to keeping the service safe and investing in strengthening enforcement strategies.
Research also discovered groups with up to nine thousand participants selling retatrutide using the platform's integrated discovery tool, which operates like a public directory. Typing “retatrutide” immediately displays channels with thousands of members, filled with images of weight loss, positive reviews and detailed guides for preparing or administering at residence.
Within moments of entering one community, a vendor shared contact information, where most transactions occur. The vendor sent an instruction manual and guaranteed delivery within two days. When asked whether the substance was authentic, one seller said: “You can’t be sure.” Another provided a photo of a alleged testing documentation. None inquired about weight, medical conditions or previous experience.
Inside these communities, messages show black plastic parcels with Royal Mail labels, claiming to include new batches. One communication stated: “It took eight of us to load them this morning.”
Customers can choose between powder vials, mixed at residence with sterile water, or ready-to-use injectors usually priced at £160 for 20mg. When questioned how much time a injector should last, sellers give contradictory answers ranging from a few weeks to “depends on your body”.
A representative for the messaging service stated it regularly monitored harmful content on its platform including content that encouraged the “misuse of controlled medications”. The organization noted that it eliminated “millions of pieces of harmful content each day”.
“Individuals are injecting substances they can’t verify. Even if the research behind retatrutide is sound, these digital versions may not contain what they claim,” stated Jason Murphy, the director of pharmaceutical services at a pharmacy service.
A medical professional of an online medical service connected the surge in interest to recent price rises for approved weight-loss medications such as Mounjaro. “With prices increasing, individuals are turning to online platforms. But counterfeit injections are highly dangerous. You cannot know what’s contained or whether the environment they were made in was sterile,” she said.
Her staff has already seen individuals harmed by self-injection from unconfirmed sources. “We understand the frustration, but purchasing from messaging apps or communication platforms is gambling with your health,” said Wyllie. “These materials could be contaminated or incorrectly dosed.”
A spokesperson from Eli Lilly stated retatrutide was in phase 3 clinical trials and had not been evaluated or approved by any government authority globally. “Therefore at this point no one can market [it] for personal consumption,” they explained, noting that any item “misleadingly claiming itself as a company experimental substance not yet authorized … may subject patients to potentially significant medical dangers”.
