A shadow economy for unlicensed weight-loss medications is propelled by TikTok fitness influencers and sellers on communication apps, according to recent findings.
The experimental drug, which is still in research studies, is being promoted by social media influencers for its alleged fat-burning properties. Followers are urged to message these profiles directly for source information, while also obtaining promotional offers.
Separately, a flourishing trade exists on Telegram, where communities with thousands of members share “before and after” photos, administration instructions and assertions of rapid British shipping. Vendors promote the drug there before directing customers to other platforms for transactions.
Retatrutide is an investigational injection created by US drugmaker Eli Lilly. The drug affects three intestinal hormones – glucagon-like peptide-1, GIP and glucagon. Early trials suggest it could assist patients reduce up to a quarter of their body weight. Nicknamed the “triple G”, the drug is being promoted online as the next Ozempic.
However, physicians and chemists have cautions that the distribution of what remains an unapproved medication in the UK is a cause for concern and could lead to users administering products of unknown origin.
Several professionals said the popularity for the experimental drug could be linked to the increasing cost of licensed slimming treatments such as Mounjaro.
Marketing the unapproved drug on TikTok or Telegram is prohibited in the UK, as it is an unapproved medication that must not be marketed or distributed for personal consumption under the British medical regulations.
Several influencers 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 advertising and distribution can still breach medicines, advertising, and consumer regulations, risking fines, legal action or imprisonment.
According to the social media company, the service has taken down violative material and banned associated keywords and search suggestions. The company said it was committed to keeping the service safe and allocating resources in enhancing enforcement strategies.
Research also found communities with up to 9,000 participants selling retatrutide using Telegram's built-in search feature, which operates like a online catalog. Typing “retatrutide” immediately brings up channels with thousands of members, populated with images of weight loss, positive reviews and detailed guides for mixing or administering at home.
Within minutes of joining one community, a vendor posted WhatsApp details, where most purchases occur. The vendor sent an instruction manual and promised delivery within two days. When questioned whether the product was authentic, one vendor said: “You can’t be sure.” Another provided a image of a supposed testing documentation. None inquired about weight, medical conditions or previous experience.
Inside these communities, messages display dark colored packages with postal service labels, claiming to contain new batches. One message stated: “It took eight of us to load them this morning.”
Buyers can choose between dry substance containers, prepared at home with purified liquid, or pre-filled injectors typically priced at 160 pounds for 20 milligrams. When asked how much time a pen should last, vendors give conflicting responses varying between a few weeks to “depends on your body”.
A representative for Telegram said it regularly monitored dangerous material on its platform including content that encouraged the “misuse of controlled medications”. The organization noted that it removed “millions of pieces of harmful content each day”.
“People are administering materials they cannot confirm. Even if the science behind this drug is sound, these digital versions may not contain what they claim,” stated a pharmacy expert, the head of pharmaceutical services at a pharmacy service.
A medical professional of Asda Online Doctor linked the increase in interest to recent price rises for approved slimming medications such as Mounjaro. “With costs increasing, individuals are using online platforms. But counterfeit injections are highly risky. You can’t be certain what’s inside or whether the environment they were made in was clean,” she explained.
Her team has previously encountered patients injured by personal administration from unverified sources. “We understand the frustration, but buying from messaging apps or WhatsApp is taking chances with your well-being,” stated Wyllie. “These substances could be impure or improperly measured.”
A representative from Eli Lilly stated retatrutide was in phase 3 research studies and had not been evaluated or authorized by any regulatory agency globally. “Therefore at this time no one can sell [it] for personal consumption,” they said, adding that any product “falsely representing itself as a Lilly experimental product not yet authorized … may expose patients to potentially serious medical dangers”.
