A shadow market for unlicensed weight-loss medications is being driven by TikTok fitness influencers and vendors on communication apps, based on new investigations.
The experimental drug, which remains in research studies, is being advertised by social media influencers for its supposed weight-reducing properties. Viewers are urged to contact these accounts privately for source information, while also receiving discount codes.
Additionally, a robust market exists on Telegram, where communities with thousands of participants share “before and after” images, administration instructions and assertions of rapid British shipping. Sellers market the drug there before directing customers to other platforms for transactions.
Retatrutide is an investigational injection developed by American pharmaceutical company Eli Lilly. The drug affects three gut hormones – GLP-1, GIP and glucagon. Early trials suggest it could help individuals lose up to a quarter of their total weight. Nicknamed the “triple G”, the drug is being hailed online as the successor to Ozempic.
Nevertheless, physicians and pharmacists have cautions that the sale of what remains an unlicensed medication in the United Kingdom is worrisome and could lead to users injecting substances of unknown origin.
Several professionals stated the demand for the experimental drug could be connected to the increasing cost of approved weight loss treatments such as Mounjaro.
Selling retatrutide on social media or Telegram is illegal in the UK, as it is an unlicensed drug that cannot be promoted or supplied for personal consumption under the British medical regulations.
Several influencers attempt to sidestep the regulations by referring to the substance as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled substance, but promotion and supply can still breach medicines, marketing, and customer laws, risking fines, legal action or prison.
According to TikTok, the platform has removed violative material and banned related keywords and query recommendations. The organization said it was committed to keeping the service secure and investing in enhancing compliance measures.
Investigations also found groups with up to 9,000 members marketing retatrutide using the platform's built-in discovery tool, which functions like a public directory. Typing “retatrutide” immediately displays groups with thousands of members, filled with photos of slimming results, glowing reviews and detailed guides for preparing or injecting at home.
After moments of entering one community, a seller posted WhatsApp details, where most transactions occur. The vendor sent an guidebook and guaranteed delivery within 48 hours. When questioned whether the product was genuine, one vendor responded: “You can’t be sure.” Another shared a image of a supposed testing documentation. Not one asked about body mass, medical conditions or previous experience.
Inside these groups, posts display black plastic packages with postal service stickers, claiming to contain new batches. One communication read: “It took eight of us to load them this morning.”
Buyers can choose between dry substance containers, mixed at home with purified liquid, or pre-filled pens usually sold at £160 for 20 milligrams. When questioned how much time a injector should be used, sellers give contradictory responses varying between a few weeks to “depends on your body”.
A spokesperson for Telegram stated it regularly monitored dangerous content on its platform including material that promoted the “misuse of controlled medications”. The company added that it removed “millions of pieces of harmful content each day”.
“Individuals are administering substances they cannot confirm. Even if the science behind this drug is sound, these online products may not contain what they claim,” said a pharmacy expert, the head of pharmacy at a pharmacy service.
A medical professional of an online medical service connected the surge in interest to current price rises for approved weight-loss medications such as Mounjaro. “With costs increasing, patients are turning to online platforms. But fake injections are extremely dangerous. You cannot know what’s contained or whether the conditions they were produced in was clean,” she explained.
Her staff has already encountered patients injured by self-injection from unconfirmed suppliers. “We understand the frustration, but buying from messaging apps or communication platforms is gambling with your well-being,” said the doctor. “These materials could be impure or improperly measured.”
A representative from the pharmaceutical company stated retatrutide was in phase 3 research studies and had not been evaluated or approved by any government authority globally. “Therefore at this point no one can market [it] for personal consumption,” they explained, adding that any item “falsely representing itself as a company experimental product not yet authorized … may expose patients to possibly significant medical dangers”.
