An underground economy for unlicensed slimming drugs is propelled by social media fitness personalities and sellers on communication apps, according to recent findings.
The experimental drug, which is still in clinical trials, is being promoted by social media influencers for its alleged weight-reducing effects. Followers are urged to message these profiles privately for supplier links, while also receiving promotional offers.
Separately, a flourishing trade exists on messaging services, where communities with numerous of participants share “before and after” images, administration instructions and assertions of next-day British shipping. Vendors promote the substance there before directing customers to other platforms for transactions.
This medication is an experimental injectable developed by American pharmaceutical company Eli Lilly. The treatment affects three gut hormones – GLP-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Preliminary studies suggest it could help patients reduce up to 25% of their total weight. Referred to as the “triple G”, the substance is being promoted online as the next Ozempic.
Nevertheless, doctors and chemists have warned that the sale of what is still an unapproved medication in the UK is worrisome and could lead to individuals injecting products of unknown origin.
Some professionals said the demand for the experimental drug could be connected to the rising price of approved slimming products such as Mounjaro.
Selling retatrutide on TikTok or Telegram is illegal in the United Kingdom, as it is an unlicensed medication that must not be marketed or supplied for human use under the Human Medicines Regulations 2012.
Several content creators try to circumvent the rules by referring to the drug as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a restricted drug, but advertising and distribution can still breach pharmaceutical, marketing, and consumer laws, risking penalties, prosecution or prison.
Based on TikTok, the platform has removed violative material and banned related hashtags and query recommendations. The company stated it was committed to keeping the service secure and allocating resources in strengthening compliance measures.
Research also found groups with up to 9,000 members selling retatrutide using Telegram's integrated discovery tool, which operates like a online catalog. Typing “retatrutide” immediately displays channels with numerous of members, filled with images of slimming results, positive testimonials and detailed instructions for mixing or injecting at home.
After moments of joining one group, a seller shared WhatsApp details, where most purchases take place. The vendor provided an guidebook and promised delivery within 48 hours. When questioned whether the product was genuine, one vendor said: “You can’t be sure.” Another shared a photo of a alleged laboratory certificate. Not one asked about weight, medical conditions or past usage.
Inside these groups, messages show dark colored packages with Royal Mail labels, stating to contain new batches. One message 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 ready-to-use injectors typically priced at 160 pounds for 20mg. When asked how long a pen should be used, vendors give conflicting responses ranging from a few weeks to “depends on your body”.
A representative for the messaging service stated it regularly moderated dangerous content on its service including material that encouraged the “misuse of controlled medications”. The company added that it eliminated “millions of pieces of harmful content each day”.
“Individuals are injecting substances they cannot confirm. Although the science behind this drug is valid, these online versions may not contain what they claim,” stated a pharmacy expert, the director of pharmaceutical services at Chemist4U.
Dr Crystal Wyllie of an online medical service linked the increase in interest to recent cost increases for approved weight-loss medications such as Mounjaro. “With prices increasing, individuals are turning to online platforms. But counterfeit treatments are highly risky. You can’t be certain what’s inside or whether the conditions they were produced in was clean,” she said.
Her team has previously seen individuals injured by self-injection from unconfirmed suppliers. “We recognize the frustration, but purchasing from messaging apps or WhatsApp is taking chances with your health,” said Wyllie. “These materials could be impure or incorrectly dosed.”
A spokesperson from the pharmaceutical company said retatrutide was in third stage clinical trials and had not been reviewed or authorized by any regulatory agency globally. “Consequently at this point no one can sell [it] for personal consumption,” they said, noting that any item “misleadingly claiming itself as a Lilly investigational substance not yet authorized … may subject patients to possibly significant health risks”.
