An underground economy for unapproved slimming drugs is being driven by TikTok fitness influencers and sellers on communication apps, based on new investigations.
The experimental drug, which is still in clinical trials, is being promoted by online personalities for its alleged fat-burning properties. Viewers are urged to contact these profiles directly for source information, while also receiving discount codes.
Additionally, a robust market exists on messaging services, where communities with thousands of participants share “before and after” photos, administration instructions and assertions of next-day UK delivery. Sellers market the drug there before redirecting buyers to WhatsApp for purchases.
This medication is an experimental injection developed by US drugmaker Eli Lilly. The drug targets three gut hormones – glucagon-like peptide-1, GIP and pancreatic hormone. Preliminary studies suggest it could assist patients reduce up to 25% of their total weight. Referred to as the “triple G”, the drug is being hailed online as the next Ozempic.
Nevertheless, doctors and pharmacists have warned that the distribution of what remains an unlicensed drug in the UK is a cause for concern and could lead to users administering substances of unknown origin.
Several experts said the popularity for retatrutide could be connected to the increasing cost of licensed slimming treatments such as Mounjaro.
Marketing the unapproved drug on social media or messaging apps is prohibited in the UK, as it is an unlicensed medication that cannot be marketed or supplied for human use under the British medical regulations.
Several influencers attempt to circumvent the regulations by calling to the substance as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a restricted substance, but advertising and supply can still violate medicines, advertising, and consumer regulations, potentially leading to penalties, legal action or prison.
Based on TikTok, the service has removed problematic material and prohibited associated keywords and query recommendations. The company stated it was committed to maintaining the service safe and investing in enhancing compliance measures.
Research also discovered groups with up to 9,000 participants marketing the experimental drug using the platform's built-in discovery tool, which functions like a online catalog. Entering “retatrutide” instantly brings up groups with thousands of members, populated with images of weight loss, glowing testimonials and step-by-step instructions for preparing or administering at residence.
Within minutes of entering one community, a vendor posted contact information, where most purchases take place. The vendor provided an instruction manual and guaranteed shipping within two days. When asked whether the product was authentic, one seller responded: “You can’t be sure.” Another provided a photo of a supposed testing documentation. None asked about weight, medical conditions or past usage.
Inside these communities, messages show black plastic parcels with Royal Mail stickers, claiming to include new batches. One message stated: “It took eight of us to load them this morning.”
Buyers can choose between powder vials, prepared at residence with purified liquid, or ready-to-use injectors usually priced at 160 pounds for 20mg. When asked how much time a pen should be used, vendors give contradictory responses ranging from a few weeks to “depends on your body”.
A spokesperson for the messaging service stated it actively 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”.
“Individuals are administering substances they can’t verify. Although the research behind this drug is sound, these digital versions may not include what they claim,” said Jason Murphy, the director of pharmacy at a pharmacy service.
A medical professional of Asda Online Doctor linked the surge in demand to current cost increases for authorized slimming drugs such as Mounjaro. “With costs increasing, individuals are turning to online platforms. But counterfeit injections are extremely risky. You can’t be certain what’s inside or whether the conditions they were produced in was sterile,” she explained.
Her team has already seen individuals injured by self-injection from unverified suppliers. “We understand the disappointment, but purchasing from messaging apps or WhatsApp is taking chances with your well-being,” said the doctor. “These substances could be contaminated or improperly measured.”
A representative from the pharmaceutical company stated the substance was in phase 3 clinical trials and had not been reviewed or approved by any government authority globally. “Therefore at this time no one can sell [it] for personal consumption,” they explained, adding that any product “falsely representing itself as a Lilly investigational product not yet authorized … may subject users to possibly serious medical dangers”.
