An underground market for unlicensed weight-loss drugs is propelled by TikTok fitness influencers and vendors on communication apps, based on new investigations.
Retatrutide, which remains in clinical trials, is being promoted by online personalities for its supposed fat-burning properties. Viewers are encouraged to contact these profiles directly for supplier links, while also obtaining promotional offers.
Separately, a flourishing trade exists on Telegram, where communities with thousands of members share comparison images, injection guides and claims of rapid UK delivery. Sellers market the substance there before directing buyers to other platforms for transactions.
This medication is an investigational injectable created by US drugmaker Eli Lilly. The drug affects three intestinal hormones – glucagon-like peptide-1, GIP and pancreatic hormone. Preliminary studies indicate it could help patients reduce up to 25% of their body weight. Referred to as the “triple G”, the substance is being hailed digitally as the successor to Ozempic.
Nevertheless, doctors and pharmacists have warned that the distribution of what remains an unapproved medication in the United Kingdom is a cause for concern and could result in users injecting substances of uncertain source.
Some professionals said the popularity for the experimental drug could be linked to the rising cost of licensed slimming treatments such as Mounjaro.
Selling retatrutide on TikTok or Telegram is illegal in the United Kingdom, as it is an unlicensed medication that cannot be marketed or supplied for human use under the Human Medicines Regulations 2012.
Several content creators attempt to circumvent the rules by referring to the drug as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a controlled substance, but promotion and supply can still breach pharmaceutical, advertising, and consumer laws, risking fines, legal action or prison.
According to TikTok, the platform has removed problematic material and banned related hashtags and search suggestions. The company said it was dedicated to keeping the service safe and investing in enhancing enforcement strategies.
Investigations also found communities with up to nine thousand participants marketing retatrutide using Telegram's built-in discovery tool, which functions like a public directory. Entering “retatrutide” immediately displays groups with thousands of users, populated with photos of slimming results, glowing reviews and detailed instructions for mixing or administering at home.
After minutes of entering one community, a seller posted WhatsApp details, where the majority of transactions take place. The vendor sent an instruction manual and guaranteed delivery within 48 hours. When asked whether the substance was genuine, one seller responded: “You can’t be sure.” Another shared a image of a supposed laboratory certificate. None asked about body mass, medical conditions or previous experience.
Within these communities, posts display dark colored packages with postal service labels, stating to contain new batches. One communication stated: “It took eight of us to load them this morning.”
Buyers can select between powder vials, mixed at residence with sterile water, or ready-to-use pens typically priced at £160 for 20mg. When asked how long a pen should be used, vendors give contradictory answers varying between a few weeks to “depends on your body”.
A representative for the messaging service stated it regularly moderated harmful material on its platform including content that encouraged the “misuse of controlled medications”. The organization added that it eliminated “millions of pieces of harmful content each day”.
“People are administering materials they can’t verify. Even if the research behind this drug is sound, these digital versions may not include what they advertise,” stated a pharmacy expert, the director of pharmacy at a pharmacy service.
Dr Crystal Wyllie of an online medical service connected the increase in demand to recent price rises for authorized slimming drugs such as Mounjaro. “With prices rising, individuals are turning to online platforms. But fake treatments are highly risky. You cannot know what’s inside or whether the conditions they were produced in was sterile,” she said.
Her staff has previously encountered patients harmed by self-injection from unconfirmed sources. “We recognize the disappointment, but buying from messaging apps or communication platforms is taking chances with your well-being,” said the doctor. “These materials could be contaminated or improperly measured.”
A spokesperson from the pharmaceutical company stated the substance was in third stage research studies and had not been evaluated or approved by any government authority anywhere in the world. “Consequently at this point no one can sell [it] for human use,” they explained, adding that any item “falsely representing itself as a Lilly experimental substance not yet authorized … may expose users to potentially significant medical dangers”.
