A shadow economy for unlicensed weight-loss medications is being driven by social media fitness personalities and vendors on messaging platforms, according to new investigations.
Retatrutide, which is still in research studies, is being advertised by social media influencers for its supposed weight-reducing effects. Viewers are encouraged to message these profiles privately for source information, while also obtaining discount codes.
Additionally, a flourishing market exists on messaging services, where communities with thousands of members share comparison images, administration instructions and claims of next-day British shipping. Sellers promote the drug there before redirecting customers to other platforms for purchases.
Retatrutide is an experimental injection created by US drugmaker Eli Lilly. The treatment targets three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Early trials indicate it could assist patients reduce up to a quarter of their body weight. Nicknamed the “triple G”, the substance is being promoted digitally as the next Ozempic.
However, physicians and pharmacists have warned that the sale of what is still an unlicensed medication in the United Kingdom is a cause for concern and could result in users administering products of uncertain source.
Some experts said the popularity for the experimental drug could be connected to the rising cost of licensed weight loss products such as Mounjaro.
Selling the unapproved drug on TikTok or Telegram is prohibited in the UK, as it is an unapproved drug that cannot be promoted or supplied for personal consumption under the Human Medicines Regulations 2012.
Several influencers attempt to circumvent the regulations by calling to the substance as a “research chemical” or describing it as “not for human consumption”. The substance is not a restricted drug, but promotion and supply can still violate pharmaceutical, marketing, and customer laws, risking penalties, legal action or imprisonment.
Based on TikTok, the service has removed violative content and banned associated hashtags and query recommendations. The company stated it was committed to maintaining the platform secure and allocating resources in enhancing compliance measures.
Research also discovered groups with up to 9,000 participants marketing retatrutide using Telegram's integrated search feature, which operates like a online catalog. Entering “retatrutide” instantly brings up channels with numerous of users, populated with photos of weight loss, glowing reviews and step-by-step instructions for mixing or administering at residence.
After moments of joining one group, a seller posted WhatsApp details, where most transactions occur. The vendor sent an guidebook and guaranteed shipping within 48 hours. When questioned whether the substance was authentic, one seller responded: “You can’t be sure.” Another shared a photo of a supposed testing documentation. Not one inquired about weight, health issues or past usage.
Inside these groups, messages show dark colored packages with Royal Mail stickers, claiming to contain new batches. One communication stated: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, prepared at home with sterile water, or pre-filled pens typically priced at 160 pounds for 20mg. When asked how long a injector should be used, vendors give conflicting responses ranging from a few weeks to “depends on your body”.
A spokesperson for Telegram said it actively monitored dangerous material on its platform including material that encouraged the “misuse of controlled medications”. The company noted that it removed “millions of pieces of harmful content each day”.
“Individuals are administering substances they cannot confirm. Although the science behind this drug is valid, these digital versions may not include what they advertise,” said Jason Murphy, the director of pharmacy at a pharmacy service.
Dr Crystal Wyllie of Asda Online Doctor connected the increase in demand to recent cost increases for authorized weight-loss medications such as Mounjaro. “With costs rising, individuals are using online platforms. But fake treatments are highly dangerous. You can’t be certain what’s contained or whether the environment they were produced in was clean,” she said.
Her team has previously encountered patients harmed by self-injection from unconfirmed suppliers. “We recognize the frustration, but purchasing from messaging apps or WhatsApp is gambling with your well-being,” said the doctor. “These materials could be impure or incorrectly dosed.”
A spokesperson from the pharmaceutical company said the substance was in phase 3 research studies and had not been evaluated or authorized by any regulatory agency anywhere in the world. “Consequently at this point no one can sell [it] for human use,” they said, noting that any product “falsely representing itself as a Lilly experimental product not yet approved … may expose users to potentially significant health risks”.
