An underground economy for unapproved slimming medications is being driven by TikTok fitness influencers and vendors on communication apps, according to new investigations.
Retatrutide, which remains in research studies, is being advertised by social media influencers for its supposed weight-reducing effects. Viewers are encouraged to message these accounts privately for supplier links, while also obtaining discount codes.
Additionally, a robust market exists on messaging services, where groups with thousands of participants share comparison images, injection guides and claims of rapid UK delivery. Vendors promote the drug there before redirecting buyers to WhatsApp for purchases.
Retatrutide is an investigational injection created by American pharmaceutical company Eli Lilly. The treatment targets three gut hormones – glucagon-like peptide-1, GIP and glucagon. Early trials suggest it could assist patients reduce up to a quarter of their body weight. Referred to as the “triple G”, the substance is being promoted digitally as the next Ozempic.
Nevertheless, doctors and chemists have cautions that the distribution of what is still an unapproved drug in the United Kingdom is worrisome and could lead to individuals administering substances of unknown origin.
Some experts stated the demand for the experimental drug could be linked to the increasing price of approved weight loss products such as Mounjaro.
Marketing retatrutide on social media or messaging apps is prohibited in the United Kingdom, as it is an unapproved medication that must not be marketed or distributed for human use under the Human Medicines Regulations 2012.
Several influencers try to sidestep the regulations by referring to the substance as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a controlled substance, but advertising and distribution can still violate medicines, marketing, and consumer laws, risking fines, legal action or prison.
Based on TikTok, the service has removed violative material and prohibited associated hashtags and search suggestions. The company said it was dedicated to keeping the platform safe and investing in strengthening enforcement strategies.
Research also found communities with up to 9,000 participants marketing the experimental drug using Telegram's integrated search feature, which operates like a public directory. Typing “retatrutide” instantly brings up groups with numerous of users, filled with images of weight loss, positive reviews and detailed instructions for preparing or injecting at residence.
After moments of joining one group, a vendor posted WhatsApp details, where most purchases occur. The vendor provided an guidebook and guaranteed delivery within 48 hours. When asked whether the product was authentic, one seller responded: “You can’t be sure.” Another shared a photo of a alleged testing documentation. None asked about weight, medical conditions or past usage.
Within these groups, posts display dark colored packages with Royal Mail labels, stating to contain new batches. One message read: “It took eight of us to load them this morning.”
Buyers can choose between powder vials, prepared at home with sterile water, or ready-to-use pens usually sold at 160 pounds for 20mg. When asked how much time a pen should last, sellers give contradictory responses ranging from a several days to “depends on your body”.
A spokesperson for Telegram said it regularly monitored dangerous content on its platform including content that promoted the “misuse of controlled medications”. The organization added that it eliminated “millions of pieces of harmful content each day”.
“People are injecting substances they cannot confirm. Although the science behind retatrutide is valid, these online products may not contain what they advertise,” said Jason Murphy, the director of pharmacy at a pharmacy service.
A medical professional of an online medical service linked the increase in interest to recent price rises for authorized slimming drugs such as Mounjaro. “With prices rising, patients are turning to social media. But fake injections are highly dangerous. You cannot know what’s inside or whether the conditions they were produced in was sterile,” she explained.
Her staff has previously seen patients injured by personal administration from unverified suppliers. “We understand the frustration, but buying from Telegram or communication platforms is gambling with your health,” stated Wyllie. “These materials could be contaminated or incorrectly dosed.”
A representative from Eli Lilly stated the substance was in third stage research studies and had not been reviewed or approved by any government authority anywhere in the world. “Consequently at this time no one can sell [it] for human use,” they explained, adding that any product “falsely representing itself as a company experimental product not yet authorized … may expose patients to possibly serious health risks”.
