A shadow economy for unlicensed slimming medications is being driven by TikTok fitness influencers and vendors on communication apps, according to recent findings.
Retatrutide, which is still in research studies, is being promoted by social media influencers for its supposed fat-burning properties. Viewers are encouraged to contact these profiles directly for supplier links, while also receiving promotional offers.
Additionally, a flourishing trade exists on messaging services, where groups with thousands of participants share “before and after” photos, injection guides and claims of rapid British shipping. Vendors market the drug there before redirecting customers to WhatsApp for purchases.
This medication is an experimental injectable created by American pharmaceutical company Eli Lilly. The drug affects three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials indicate it could assist patients reduce up to a quarter of their body weight. Nicknamed the “triple G”, the drug is being hailed digitally as the successor to 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 lead to users administering substances of unknown origin.
Some experts stated the demand for retatrutide could be linked to the increasing cost of approved slimming products such as Mounjaro.
Marketing the unapproved drug on TikTok or Telegram is illegal in the United Kingdom, as it is an unlicensed medication that cannot be marketed or distributed for human use under the British medical regulations.
Several content creators attempt to circumvent the regulations by calling to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a restricted substance, but advertising and distribution can still violate pharmaceutical, marketing, and customer regulations, potentially leading to fines, legal action or prison.
Based on TikTok, the platform has removed problematic material and banned associated keywords and query recommendations. The organization said it was dedicated to maintaining the platform secure and allocating resources in enhancing enforcement strategies.
Research also found communities with up to 9,000 members marketing retatrutide using the platform's integrated discovery tool, which functions like a online catalog. Typing “retatrutide” immediately displays groups with thousands of users, filled with images of weight loss, glowing reviews and step-by-step instructions for preparing or administering at home.
After moments of entering one group, a vendor posted contact information, where the majority of transactions take place. The vendor provided an guidebook and guaranteed shipping within two days. When asked whether the substance was genuine, one vendor responded: “You can’t be sure.” Another provided a photo of a supposed laboratory certificate. None asked about weight, medical conditions or previous experience.
Inside these groups, posts display black plastic parcels with Royal Mail stickers, claiming to include fresh supplies. One communication read: “It took eight of us to load them this morning.”
Buyers can choose between powder vials, prepared at home with purified liquid, or pre-filled injectors typically sold at 160 pounds for 20mg. When questioned how long a pen should be used, sellers give conflicting responses ranging from a several days to “depends on your body”.
A spokesperson for the messaging service stated it regularly moderated dangerous content on its platform including content that promoted the “misuse of controlled medications”. The company added that it removed “millions of pieces of harmful content each day”.
“People are injecting materials they cannot confirm. Although the research behind this drug is sound, these online versions may not include what they claim,” stated Jason Murphy, the head of pharmaceutical services at a pharmacy service.
Dr Crystal Wyllie of Asda Online Doctor connected the surge in demand to current cost increases for approved slimming drugs such as Mounjaro. “With prices increasing, individuals are turning to online platforms. But fake treatments are highly risky. You can’t be certain what’s inside or whether the conditions they were made in was sterile,” she said.
Her staff has previously seen individuals injured by self-injection from unconfirmed suppliers. “We understand the disappointment, but buying from Telegram or WhatsApp is gambling with your health,” said Wyllie. “These materials could be contaminated or incorrectly dosed.”
A representative from Eli Lilly stated retatrutide was in phase 3 research studies and had not been evaluated or authorized by any government authority anywhere in the world. “Therefore at this point no one can market [it] for personal consumption,” they explained, noting that any item “falsely representing itself as a company experimental product not yet authorized … may subject users to potentially serious health risks”.
