An underground market for unapproved slimming drugs is being driven by social media fitness personalities and vendors on communication apps, according to recent findings.
Retatrutide, which remains in clinical trials, is being advertised by online personalities for its alleged weight-reducing effects. Viewers are urged to message these accounts privately for supplier links, while also obtaining discount codes.
Additionally, a robust market exists on Telegram, where communities with thousands of members share “before and after” photos, administration instructions and claims of next-day British shipping. Vendors market the drug there before redirecting buyers to WhatsApp for purchases.
Retatrutide is an investigational injectable developed by US drugmaker Eli Lilly. The drug targets three gut hormones – GLP-1, GIP and glucagon. Early trials suggest it could assist individuals reduce up to a quarter of their total weight. Referred to as the “triple G”, the substance is being promoted online as the successor to Ozempic.
However, physicians and pharmacists have warned that the distribution of what is still an unapproved medication in the UK is a cause for concern and could lead to individuals administering substances of uncertain source.
Some professionals said the popularity for retatrutide could be connected to the increasing price of approved slimming treatments such as Mounjaro.
Marketing the unapproved drug on social media or messaging apps is illegal in the United Kingdom, as it is an unlicensed drug that must not be marketed or distributed for personal consumption under the British medical regulations.
Some 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 advertising and supply can still breach medicines, advertising, and customer laws, potentially leading to penalties, prosecution or imprisonment.
According to TikTok, the platform has taken down violative content and prohibited associated keywords and query recommendations. The organization said it was committed to maintaining the service secure and allocating resources in strengthening enforcement strategies.
Investigations also discovered communities with up to nine thousand members selling retatrutide using the platform's built-in search feature, which operates like a online catalog. Typing “retatrutide” immediately brings up groups with thousands of members, populated with images of weight loss, positive reviews and step-by-step guides for preparing or injecting at residence.
Within moments of entering one group, a seller posted WhatsApp details, where most purchases take place. The vendor sent an instruction manual and guaranteed delivery within 48 hours. When questioned whether the product was genuine, one vendor responded: “You can’t be sure.” Another provided a image of a alleged laboratory certificate. None inquired about body mass, health issues or past usage.
Inside these communities, messages show dark colored packages 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, mixed at home with sterile water, or pre-filled injectors usually priced at £160 for 20mg. When questioned how long a pen should be used, vendors give conflicting answers ranging from a few weeks 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 company added that it eliminated “millions of pieces of harmful content each day”.
“Individuals are injecting substances they can’t verify. Although the research behind this drug is valid, these digital versions may not contain what they claim,” said a pharmacy expert, the director of pharmacy at Chemist4U.
Dr Crystal Wyllie of an online medical service connected the surge in interest to current cost increases for authorized slimming medications such as Mounjaro. “With prices increasing, individuals are using social media. But fake injections are extremely risky. You can’t be certain what’s inside or whether the conditions they were made in was clean,” she said.
Her staff has already encountered patients harmed by personal administration from unconfirmed suppliers. “We understand the disappointment, but purchasing from Telegram or WhatsApp is taking chances with your well-being,” stated Wyllie. “These substances could be impure or incorrectly dosed.”
A representative from the pharmaceutical company stated retatrutide was in third stage clinical trials and had not been reviewed or approved by any regulatory agency globally. “Therefore at this time no one can sell [it] for human use,” they explained, noting that any product “falsely representing itself as a company investigational product not yet approved … may expose users to potentially serious health risks”.
