A shadow economy for unapproved weight-loss medications is propelled by social media fitness personalities and sellers on communication apps, based on recent findings.
Retatrutide, which is still in research studies, is being advertised by social media influencers for its supposed fat-burning effects. Followers are encouraged to contact these accounts privately for supplier links, while also receiving promotional offers.
Separately, a flourishing market exists on Telegram, where groups with numerous of members share “before and after” photos, injection guides and claims of rapid British shipping. Sellers market the substance there before directing customers to other platforms for purchases.
Retatrutide is an experimental injection created by American pharmaceutical company Eli Lilly. The drug targets three gut hormones – GLP-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Preliminary studies indicate it could assist individuals lose up to a quarter of their body weight. Nicknamed the “triple G”, the substance is being promoted digitally as the successor to Ozempic.
Nevertheless, doctors and pharmacists have warned that the sale of what is still an unapproved medication in the UK is a cause for concern and could lead to users administering products of unknown origin.
Several professionals stated the demand for the experimental drug could be connected to the rising price of licensed weight loss treatments such as Mounjaro.
Selling retatrutide on social media or Telegram is illegal in the UK, as it is an unlicensed medication that must not be marketed or distributed for human use under the Human Medicines Regulations 2012.
Some influencers try to circumvent the rules by referring to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a restricted substance, but advertising and supply can still breach medicines, marketing, and customer regulations, potentially leading to fines, prosecution or prison.
Based on TikTok, the platform has taken down violative content and prohibited related hashtags and query recommendations. The organization said it was committed to keeping the platform secure and investing in strengthening compliance measures.
Research also discovered groups with up to 9,000 participants selling retatrutide using the platform's integrated discovery tool, which functions like a public directory. Typing “retatrutide” instantly brings up channels with thousands of users, filled with images of weight loss, glowing testimonials and detailed guides for mixing or administering at residence.
Within minutes of entering one group, a seller shared WhatsApp details, where the majority of transactions occur. The vendor sent an instruction manual and promised delivery within two days. When asked whether the substance was genuine, one seller responded: “You can’t be sure.” Another provided a image of a supposed laboratory certificate. None asked about body mass, health issues or past usage.
Inside these communities, messages display black plastic packages with Royal Mail labels, claiming to include new batches. One message stated: “It took eight of us to load them this morning.”
Customers can select between powder vials, prepared at residence with sterile water, or ready-to-use pens usually priced at £160 for 20 milligrams. When questioned how long a injector should be used, vendors give contradictory answers ranging from a several days to “depends on your body”.
A spokesperson for Telegram said it actively moderated harmful material on its platform including material that encouraged the “misuse of controlled medications”. The organization noted that it eliminated “millions of pieces of harmful content each day”.
“People are injecting materials they can’t verify. Although the science behind retatrutide is sound, these digital versions may not include what they advertise,” said a pharmacy expert, the director of pharmaceutical services at Chemist4U.
Dr Crystal Wyllie of Asda Online Doctor connected the increase in interest to current cost increases for approved weight-loss drugs such as Mounjaro. “With prices increasing, patients are turning to social media. But fake injections are extremely dangerous. You can’t be certain what’s inside 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 understand the disappointment, but purchasing from Telegram or WhatsApp is gambling with your health,” stated Wyllie. “These substances could be contaminated or incorrectly dosed.”
A spokesperson from the pharmaceutical company stated retatrutide was in phase 3 research studies and had not been reviewed or approved by any government authority globally. “Consequently at this point no one can market [it] for personal consumption,” they said, adding that any item “falsely representing itself as a company experimental substance not yet approved … may expose patients to potentially significant medical dangers”.
