An underground market for unapproved weight-loss medications is propelled by TikTok fitness influencers and sellers on messaging platforms, based on new investigations.
Retatrutide, which is still in clinical trials, is being advertised by online personalities for its supposed fat-burning properties. Viewers are encouraged to contact these profiles directly for supplier links, while also receiving discount codes.
Separately, a flourishing market exists on Telegram, where communities with numerous of members share “before and after” images, injection guides and claims of next-day UK delivery. Sellers promote the substance there before redirecting customers to WhatsApp for purchases.
This medication is an investigational injectable created by American pharmaceutical company Eli Lilly. The treatment affects three intestinal hormones – GLP-1, GIP and pancreatic hormone. Early trials indicate it could help individuals lose up to a quarter of their body weight. Referred to as the “triple G”, the drug is being promoted online as the next Ozempic.
However, physicians and pharmacists have cautions that the sale of what remains an unlicensed drug in the United Kingdom is a cause for concern and could result in users injecting substances of unknown origin.
Several professionals said the demand for the experimental drug could be connected to the increasing cost of approved weight loss treatments such as Mounjaro.
Marketing retatrutide on TikTok or Telegram is illegal in the UK, as it is an unlicensed medication that cannot be promoted or supplied for personal consumption under the British medical regulations.
Some content creators try to circumvent the rules by referring to the substance as a “research chemical” or citing it as “not for human consumption”. The substance is not a restricted substance, but promotion and supply can still breach medicines, advertising, and consumer laws, risking fines, prosecution or imprisonment.
According to TikTok, the service has taken down problematic content and banned related keywords and query recommendations. The organization stated it was dedicated to keeping the platform safe and allocating resources in strengthening compliance measures.
Investigations also found groups with up to nine thousand participants marketing the experimental drug using the platform's integrated discovery tool, which functions like a public directory. Typing “retatrutide” immediately displays groups with thousands of members, filled with images of weight loss, positive reviews and detailed instructions for preparing or injecting at residence.
After moments of joining one community, a seller shared WhatsApp details, where most purchases take place. The vendor provided an instruction manual and guaranteed delivery within two days. When questioned whether the substance was genuine, one seller said: “You can’t be sure.” Another shared a image of a alleged testing documentation. None asked about weight, health issues or previous experience.
Within these communities, posts show dark colored 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 dry substance containers, prepared at residence with purified liquid, or pre-filled injectors typically priced at £160 for 20 milligrams. When asked how much time a pen should last, vendors give conflicting answers varying between a several days to “depends on your body”.
A spokesperson for Telegram said it regularly moderated harmful material on its service including material that promoted the “misuse of controlled medications”. The organization added that it eliminated “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,” said a pharmacy expert, the head of pharmaceutical services at a pharmacy service.
Dr Crystal Wyllie of Asda Online Doctor linked the surge in interest to recent cost increases for approved slimming medications such as Mounjaro. “With prices rising, individuals are turning to online platforms. But fake treatments are extremely risky. You cannot know what’s inside or whether the conditions they were made in was clean,” she explained.
Her team has already encountered individuals injured by self-injection from unverified suppliers. “We understand the disappointment, but buying from Telegram or communication platforms is gambling with your health,” said Wyllie. “These substances could be impure or incorrectly dosed.”
A spokesperson from Eli Lilly stated the substance was in third stage research studies and had not been reviewed or authorized by any regulatory agency anywhere in the world. “Consequently at this point no one can market [it] for human use,” they said, noting that any product “falsely representing itself as a Lilly investigational product not yet approved … may expose patients to possibly serious medical dangers”.
