A shadow economy for unlicensed slimming medications is being driven by social media fitness personalities and sellers on messaging platforms, based on new investigations.
Retatrutide, which is still in research studies, is being promoted by online personalities for its alleged fat-burning effects. Viewers are urged to contact these profiles privately for supplier links, while also obtaining promotional offers.
Additionally, a flourishing market exists on messaging services, where groups with thousands of members share “before and after” photos, injection guides and assertions of next-day British shipping. Sellers promote the substance there before directing customers to other platforms for purchases.
This medication is an investigational injection developed by US drugmaker Eli Lilly. The drug targets three gut hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials suggest it could help individuals reduce up to 25% of their total weight. Nicknamed the “triple G”, the substance is being promoted digitally as the successor to Ozempic.
Nevertheless, doctors and chemists have warned that the distribution of what is still an unlicensed drug in the United Kingdom is worrisome and could lead to individuals injecting products of uncertain source.
Some experts said the demand for retatrutide could be connected to the increasing price of licensed weight loss treatments such as Mounjaro.
Selling retatrutide on TikTok or messaging apps is illegal in the UK, as it is an unapproved medication that must not be marketed or distributed for human use under the British medical regulations.
Some influencers attempt to circumvent the regulations by referring to the drug as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a restricted drug, but promotion and distribution can still violate medicines, marketing, and customer laws, potentially leading to penalties, prosecution or prison.
According to the social media company, the service has removed problematic content and banned associated keywords and query recommendations. The company stated it was dedicated to maintaining the platform safe and allocating resources in strengthening compliance measures.
Research also found communities with up to 9,000 members selling the experimental drug using the platform's integrated discovery tool, which operates like a public directory. Typing “retatrutide” instantly brings up channels with numerous of users, populated with images of slimming results, positive reviews and step-by-step instructions for preparing or injecting at home.
Within moments of joining one community, a vendor shared contact information, where most transactions take place. The vendor provided an instruction manual and guaranteed delivery within 48 hours. When questioned whether the substance was authentic, one seller responded: “You can’t be sure.” Another provided a image of a alleged testing documentation. Not one asked about body mass, medical conditions or previous experience.
Within these communities, messages show dark colored packages with Royal Mail stickers, stating to include fresh supplies. One message stated: “It took eight of us to load them this morning.”
Buyers can select between powder vials, mixed at home with sterile water, or ready-to-use pens usually priced at £160 for 20mg. When asked how long a pen should last, sellers give contradictory responses ranging from a several days to “depends on your body”.
A spokesperson for Telegram said it actively monitored harmful material on its service including material that encouraged the “misuse of controlled medications”. The company added that it removed “millions of pieces of harmful content each day”.
“Individuals are administering substances they can’t verify. Even if the science behind this drug is sound, these online products may not include what they claim,” said a pharmacy expert, the director of pharmaceutical services at Chemist4U.
A medical professional of an online medical service connected the surge in interest to recent price rises for authorized weight-loss drugs such as Mounjaro. “With costs increasing, patients are using online platforms. But fake injections are extremely dangerous. You can’t be certain what’s inside or whether the conditions they were made in was sterile,” she explained.
Her staff has previously encountered individuals injured by self-injection from unverified sources. “We recognize the frustration, but purchasing from messaging apps or communication platforms is taking chances with your well-being,” said the doctor. “These substances could be contaminated or incorrectly dosed.”
A spokesperson from the pharmaceutical company said retatrutide was in phase 3 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 personal consumption,” they explained, noting that any product “falsely representing itself as a company investigational product not yet authorized … may subject users to potentially serious health risks”.
