A shadow market for unlicensed weight-loss medications is being driven by social media fitness personalities and vendors on messaging platforms, according to recent findings.
Retatrutide, which remains in research studies, is being promoted by social media influencers for its alleged weight-reducing properties. Followers are urged to contact these profiles privately for source information, while also receiving discount codes.
Separately, a robust market exists on messaging services, where communities with thousands of participants share comparison photos, injection guides and claims of rapid UK delivery. Sellers market the substance there before directing buyers to other platforms for purchases.
Retatrutide is an investigational injectable developed by American pharmaceutical company Eli Lilly. The drug affects three gut hormones – GLP-1, GIP and glucagon. Early trials suggest it could help patients reduce up to a quarter of their total weight. Referred to as the “triple G”, the drug is being promoted online as the successor to Ozempic.
However, doctors and pharmacists have warned that the distribution of what remains an unlicensed medication in the UK is worrisome and could result in individuals injecting products of uncertain source.
Several experts said the demand for the experimental drug could be connected to the increasing cost of licensed slimming treatments such as Mounjaro.
Marketing the unapproved drug on TikTok or Telegram is prohibited in the UK, as it is an unlicensed drug that cannot be marketed or distributed for personal consumption under the Human Medicines Regulations 2012.
Several content creators try to sidestep the rules by referring to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a restricted drug, but promotion and supply can still breach pharmaceutical, marketing, and consumer regulations, risking fines, legal action or imprisonment.
Based on the social media company, the service has taken down violative content and prohibited related hashtags and search suggestions. The organization stated it was dedicated to keeping the platform secure and allocating resources in strengthening enforcement strategies.
Investigations also found groups with up to nine thousand members marketing retatrutide using the platform's integrated search feature, which functions like a public directory. Typing “retatrutide” instantly brings up channels with numerous of users, filled with images of slimming results, glowing testimonials and step-by-step instructions for mixing or injecting at residence.
Within moments of entering one community, a seller shared WhatsApp details, where the majority of transactions occur. The seller provided an guidebook and guaranteed shipping within 48 hours. When asked whether the substance was genuine, one seller said: “You can’t be sure.” Another provided a photo of a alleged testing documentation. None inquired about body mass, medical conditions or previous experience.
Within these groups, posts show black plastic packages with postal service stickers, stating to contain new batches. One message read: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, prepared at residence with purified liquid, or ready-to-use injectors usually priced at £160 for 20mg. When questioned how much time a injector should last, vendors give contradictory answers varying between a few weeks to “depends on your body”.
A spokesperson for Telegram said it actively moderated harmful material on its service including content that promoted the “misuse of controlled medications”. The organization noted that it eliminated “millions of pieces of harmful content each day”.
“Individuals are injecting materials they cannot confirm. Although the research behind retatrutide is valid, these online products may not contain what they claim,” stated a pharmacy expert, the director of pharmaceutical services at a pharmacy service.
A medical professional of an online medical service linked the surge in interest to recent price rises for authorized weight-loss medications such as Mounjaro. “With costs rising, patients are using social media. But fake injections are extremely dangerous. You cannot know what’s contained or whether the environment they were produced in was sterile,” she explained.
Her staff has already encountered patients injured by self-injection from unconfirmed suppliers. “We understand the frustration, but purchasing from messaging apps or WhatsApp is gambling with your health,” said Wyllie. “These materials could be contaminated or improperly measured.”
A spokesperson from the pharmaceutical company stated the substance was in third stage clinical trials and had not been evaluated or approved by any regulatory agency anywhere in the world. “Consequently at this point no one can sell [it] for human use,” they explained, adding that any item “misleadingly claiming itself as a company investigational substance not yet approved … may subject patients to possibly serious health risks”.
