An underground economy for unapproved weight-loss medications is being driven by TikTok fitness influencers and sellers on communication apps, based on recent findings.
Retatrutide, which remains in research studies, is being advertised by social media influencers for its supposed fat-burning effects. Followers are urged to contact these profiles privately for source information, while also obtaining discount codes.
Additionally, a robust trade exists on Telegram, where groups with thousands of participants share “before and after” images, administration instructions and claims of rapid UK delivery. Sellers market the drug there before directing customers to other platforms for purchases.
This medication is an experimental injection developed by American pharmaceutical company Eli Lilly. The treatment targets three gut hormones – GLP-1, GIP and pancreatic hormone. Preliminary studies indicate it could assist patients lose up to 25% of their total weight. Nicknamed the “triple G”, the substance is being hailed online as the next Ozempic.
However, doctors and chemists have warned that the distribution of what remains an unlicensed drug in the UK is worrisome and could lead to individuals administering products of unknown origin.
Some professionals said the popularity for the experimental drug could be connected to the rising price of approved weight loss treatments such as Mounjaro.
Selling retatrutide on social media or Telegram is prohibited in the UK, as it is an unlicensed medication that must not be promoted or distributed for human use under the Human Medicines Regulations 2012.
Several influencers try to sidestep the rules by referring to the substance as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a controlled drug, but advertising and supply can still violate pharmaceutical, advertising, and consumer regulations, risking fines, prosecution or imprisonment.
According to the social media company, the service has taken down violative material and prohibited associated hashtags and search suggestions. The organization stated it was committed to keeping the service secure and allocating resources in enhancing compliance measures.
Investigations also discovered communities with up to 9,000 participants selling the experimental drug using the platform's built-in search feature, which functions like a online catalog. Entering “retatrutide” immediately brings up channels with thousands of users, populated with photos of slimming results, positive testimonials and step-by-step guides for mixing or injecting at home.
After moments of entering one community, a vendor posted WhatsApp details, where most transactions occur. The seller provided an guidebook and promised delivery within 48 hours. When asked whether the substance was authentic, one seller responded: “You can’t be sure.” Another provided a photo of a alleged testing documentation. None asked about body mass, health issues or past usage.
Inside these groups, posts display black plastic parcels with postal service stickers, stating to include fresh supplies. One communication read: “It took eight of us to load them this morning.”
Customers can choose between powder vials, mixed at home with sterile water, or ready-to-use pens usually priced at £160 for 20 milligrams. When asked how long a injector should last, vendors give conflicting responses ranging from a few weeks to “depends on your body”.
A representative for Telegram stated it actively moderated harmful material on its service including content that promoted the “misuse of controlled medications”. The company noted that it eliminated “millions of pieces of harmful content each day”.
“People are injecting materials they cannot confirm. Even if the research behind this drug is valid, these online products may not include what they advertise,” said Jason Murphy, the head of pharmacy at a pharmacy service.
Dr Crystal Wyllie of Asda Online Doctor connected the surge in interest to current price rises for authorized slimming drugs such as Mounjaro. “With prices increasing, individuals are using online platforms. But fake treatments are highly risky. You can’t be certain what’s contained or whether the conditions they were made in was clean,” she explained.
Her team has previously seen patients injured by self-injection from unconfirmed sources. “We recognize the frustration, but purchasing from messaging apps or WhatsApp is gambling with your well-being,” stated Wyllie. “These materials could be contaminated or improperly measured.”
A representative from the pharmaceutical company said the substance was in third stage clinical trials and had not been evaluated or approved by any regulatory agency globally. “Therefore at this time no one can market [it] for personal consumption,” they explained, adding that any product “misleadingly claiming itself as a company experimental substance not yet approved … may subject patients to potentially significant health risks”.
