An underground market for unapproved weight-loss medications is propelled by TikTok fitness influencers and vendors on communication apps, based on new investigations.
The experimental drug, which remains in research studies, is being advertised 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 market exists on Telegram, where communities with numerous of members share “before and after” images, injection guides and assertions of next-day UK delivery. Sellers promote the substance there before redirecting customers to other platforms for purchases.
Retatrutide is an experimental injection created by American pharmaceutical company Eli Lilly. The treatment affects three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials suggest it could help patients lose up to a quarter of their total weight. Referred to as the “triple G”, the substance is being promoted digitally as the successor to Ozempic.
However, physicians and chemists have warned that the distribution of what is still an unlicensed medication in the UK is worrisome and could lead to individuals injecting substances of unknown origin.
Several professionals said the demand for retatrutide could be linked to the rising price of licensed slimming products such as Mounjaro.
Marketing retatrutide on TikTok or Telegram is illegal in the UK, as it is an unapproved drug that cannot be marketed or supplied for personal consumption under the Human Medicines Regulations 2012.
Several content creators attempt to sidestep the rules by calling to the drug 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 breach medicines, advertising, and customer laws, potentially leading to penalties, prosecution or prison.
Based on TikTok, the service has taken down problematic material and prohibited related keywords and search suggestions. The organization stated it was committed to maintaining the service safe and investing in strengthening enforcement strategies.
Investigations also discovered groups with up to nine thousand members selling retatrutide using the platform's built-in search feature, which operates like a public directory. Entering “retatrutide” immediately brings up channels with thousands of users, filled with images of slimming results, positive reviews and step-by-step guides for mixing or administering at residence.
Within moments of entering one group, a seller posted WhatsApp details, where most transactions take place. The seller sent an guidebook and guaranteed shipping within two days. When questioned whether the product was authentic, one vendor said: “You can’t be sure.” Another provided a image of a alleged testing documentation. None asked about body mass, medical conditions or previous experience.
Within these communities, messages show black plastic parcels with postal service stickers, claiming to include new batches. One message stated: “It took eight of us to load them this morning.”
Buyers can select between powder vials, mixed at residence with purified liquid, or pre-filled injectors typically priced at £160 for 20 milligrams. When questioned how much time a injector should be used, vendors give conflicting responses ranging from a several days to “depends on your body”.
A spokesperson for Telegram said it regularly monitored dangerous content 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 online products may not include what they advertise,” said Jason Murphy, the head of pharmacy at a pharmacy service.
Dr Crystal Wyllie of an online medical service connected the increase in interest to current price rises for approved weight-loss medications such as Mounjaro. “With prices increasing, individuals are turning to online platforms. But fake treatments are highly dangerous. You can’t be certain what’s inside or whether the conditions they were made in was sterile,” she explained.
Her team has previously encountered individuals injured by personal administration from unverified suppliers. “We understand the frustration, but buying from messaging apps or WhatsApp is gambling with your health,” said Wyllie. “These materials could be contaminated or improperly measured.”
A representative from Eli Lilly stated retatrutide was in third stage clinical trials and had not been reviewed or approved by any regulatory agency globally. “Consequently at this time no one can market [it] for personal consumption,” they explained, adding that any item “misleadingly claiming itself as a Lilly investigational substance not yet authorized … may expose users to possibly significant medical dangers”.
