A shadow market for unapproved slimming drugs is propelled by TikTok fitness influencers and sellers on messaging platforms, based on new investigations.
The experimental drug, which is still in clinical trials, is being promoted by social media influencers for its alleged fat-burning effects. Followers are encouraged to message these accounts directly for source information, while also receiving discount codes.
Separately, a robust trade exists on messaging services, where groups with thousands of participants share comparison photos, injection guides and assertions of next-day UK delivery. Sellers promote the drug there before directing customers to WhatsApp for purchases.
Retatrutide is an experimental injection created by American pharmaceutical company Eli Lilly. The drug affects three intestinal hormones – GLP-1, GIP and glucagon. Early trials suggest it could help individuals lose up to 25% of their body weight. Referred to as the “triple G”, the substance is being promoted digitally as the successor to Ozempic.
Nevertheless, physicians and chemists have cautions that the sale of what remains an unapproved medication in the UK is worrisome and could lead to individuals administering products of unknown origin.
Several professionals stated the demand for the experimental drug could be connected to the rising price of approved weight loss treatments such as Mounjaro.
Marketing retatrutide on social media or Telegram is illegal in the UK, as it is an unapproved medication that must not be marketed or supplied for human use under the British medical regulations.
Several content creators attempt to sidestep the rules by calling to the substance as a “research chemical” or citing it as “not for human consumption”. The substance is not a controlled drug, but advertising and distribution can still breach pharmaceutical, marketing, and consumer regulations, potentially leading to fines, prosecution or prison.
Based on TikTok, the service has removed problematic material and prohibited related keywords and search suggestions. The organization stated it was committed to keeping the service secure and investing in enhancing enforcement strategies.
Research also discovered communities with up to nine thousand members marketing the experimental drug using the platform's built-in search feature, which operates like a public directory. Typing “retatrutide” immediately displays groups with thousands of members, populated with photos of slimming results, glowing reviews and detailed guides for preparing or injecting at home.
After minutes of entering one group, a vendor shared WhatsApp details, where most purchases occur. The vendor sent an instruction manual and guaranteed shipping within 48 hours. When questioned whether the product was genuine, one seller responded: “You can’t be sure.” Another provided a photo of a supposed testing documentation. Not one asked about weight, health issues or past usage.
Inside these communities, posts show black plastic parcels with postal service stickers, stating to include fresh supplies. One communication read: “It took eight of us to load them this morning.”
Customers can select between powder vials, prepared at home with purified liquid, or pre-filled pens usually sold at £160 for 20mg. When asked how much time a injector should be used, sellers give conflicting answers varying between a few weeks to “depends on your body”.
A representative for the messaging service said it regularly monitored dangerous material on its platform including material that promoted the “misuse of controlled medications”. The company noted that it removed “millions of pieces of harmful content each day”.
“Individuals are administering materials they can’t verify. Even if the research behind retatrutide is sound, these digital versions may not contain what they claim,” stated a pharmacy expert, the head of pharmaceutical services at Chemist4U.
A medical professional of Asda Online Doctor connected the surge in interest to recent cost increases for authorized slimming medications such as Mounjaro. “With prices increasing, patients are using social media. But fake injections are extremely risky. You can’t be certain what’s contained or whether the conditions they were made in was clean,” she said.
Her team has already seen individuals injured by self-injection from unverified suppliers. “We understand the frustration, but buying from messaging apps or WhatsApp is gambling with your health,” stated the doctor. “These substances could be impure or improperly measured.”
A spokesperson from the pharmaceutical company stated the substance was in third stage research studies and had not been reviewed or authorized by any regulatory agency 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 Lilly investigational substance not yet authorized … may subject patients to potentially serious health risks”.
