A shadow economy for unlicensed weight-loss drugs is being driven by TikTok fitness influencers and vendors on messaging platforms, according to recent findings.
Retatrutide, which remains in clinical trials, is being promoted by online personalities for its supposed fat-burning properties. Followers are urged to contact these profiles directly for source information, while also obtaining promotional offers.
Separately, a robust market exists on Telegram, where groups with thousands of participants share comparison photos, injection guides and assertions of next-day British shipping. Sellers promote the drug there before directing buyers to other platforms for purchases.
This medication is an investigational injectable created by American pharmaceutical company Eli Lilly. The treatment targets three intestinal hormones – GLP-1, GIP and pancreatic hormone. Early trials indicate it could assist patients lose up to 25% of their body weight. Nicknamed the “triple G”, the substance is being promoted digitally as the next Ozempic.
Nevertheless, doctors and chemists have cautions that the distribution of what is still an unapproved drug in the UK is a cause for concern and could lead to users administering substances of unknown origin.
Some experts said the demand for retatrutide could be connected to the increasing price of licensed weight loss treatments such as Mounjaro.
Marketing retatrutide on social media or messaging apps is prohibited in the UK, as it is an unlicensed medication that must not be promoted or distributed for personal consumption under the Human Medicines Regulations 2012.
Some influencers try to circumvent the regulations by calling to the substance as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a restricted substance, but advertising and distribution can still breach pharmaceutical, advertising, and consumer laws, potentially leading to penalties, legal action or prison.
Based on the social media company, the platform has taken down problematic material and prohibited associated keywords and query recommendations. The organization stated it was dedicated to maintaining the platform safe and investing in strengthening compliance measures.
Investigations also found communities with up to 9,000 participants selling retatrutide using Telegram's built-in search feature, which operates like a online catalog. Entering “retatrutide” instantly brings up groups with numerous of users, populated with images of slimming results, glowing reviews and detailed guides for preparing or injecting at home.
Within moments of entering one community, a seller posted WhatsApp details, where the majority of transactions take place. The seller sent an instruction manual and promised shipping within two days. When asked whether the substance was genuine, one vendor responded: “You can’t be sure.” Another shared a photo of a supposed testing documentation. Not one inquired about body mass, medical conditions or previous experience.
Within these communities, messages display dark colored parcels with Royal Mail labels, stating to include fresh supplies. One communication stated: “It took eight of us to load them this morning.”
Buyers can select between powder vials, prepared at residence with purified liquid, or ready-to-use pens usually priced at £160 for 20mg. When questioned how much time a injector should last, sellers give contradictory answers varying between a few weeks to “depends on your body”.
A representative for the messaging service stated it regularly monitored harmful content on its platform including content that encouraged the “misuse of controlled medications”. The company noted that it removed “millions of pieces of harmful content each day”.
“People are administering materials they cannot confirm. Although the science behind this drug is sound, these online products may not include what they advertise,” stated a pharmacy expert, the head of pharmacy at Chemist4U.
Dr Crystal Wyllie of an online medical service connected the increase in interest to recent cost increases for approved slimming medications such as Mounjaro. “With prices increasing, patients are turning to online platforms. But counterfeit injections are extremely dangerous. You can’t be certain what’s inside or whether the conditions they were made in was sterile,” she said.
Her team has already seen patients harmed by personal administration from unconfirmed sources. “We recognize the disappointment, but purchasing from Telegram or communication platforms is taking chances with your well-being,” stated the doctor. “These substances could be contaminated or improperly measured.”
A representative from the pharmaceutical company said retatrutide was in third stage research studies and had not been reviewed or approved by any regulatory agency anywhere in the world. “Consequently at this time no one can sell [it] for personal consumption,” they explained, noting that any item “falsely representing itself as a company experimental product not yet authorized … may expose patients to potentially significant health risks”.
