An underground economy for unapproved weight-loss medications is propelled by TikTok fitness influencers and sellers on messaging platforms, based on recent findings.
Retatrutide, which is still in research studies, is being promoted by social media influencers for its supposed weight-reducing effects. Viewers are urged to contact these accounts directly for supplier links, while also receiving discount codes.
Additionally, a flourishing market exists on Telegram, where communities with thousands of members share comparison images, injection guides and claims of rapid British shipping. Vendors market the substance there before directing customers to other platforms for purchases.
Retatrutide is an investigational injectable developed by American pharmaceutical company Eli Lilly. The treatment affects three gut hormones – GLP-1, GIP and glucagon. Early trials indicate it could help individuals reduce up to a quarter of their total weight. Referred to as the “triple G”, the drug is being hailed online as the successor to Ozempic.
However, doctors and pharmacists have warned that the sale of what remains an unlicensed medication in the UK is a cause for concern and could result in users administering substances of uncertain source.
Several professionals stated the popularity for the experimental drug could be connected to the increasing cost of approved weight loss treatments such as Mounjaro.
Selling 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 personal consumption under the Human Medicines Regulations 2012.
Some content creators attempt to sidestep the rules by calling 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 violate medicines, marketing, and consumer laws, potentially leading to fines, prosecution or imprisonment.
According to TikTok, the platform has removed problematic content and banned associated keywords and query recommendations. The organization said it was dedicated to maintaining the service secure and investing in strengthening compliance measures.
Investigations also found groups with up to 9,000 members selling the experimental drug using Telegram's integrated discovery tool, which operates like a online catalog. Entering “retatrutide” instantly displays groups with thousands of members, populated with images of weight loss, positive testimonials and step-by-step guides for preparing or administering at residence.
Within moments of joining one community, a vendor shared contact information, where most purchases take place. The seller provided an guidebook and guaranteed delivery within two days. When asked whether the substance was authentic, one seller said: “You can’t be sure.” Another shared a image of a supposed testing documentation. Not one asked about body mass, medical conditions or past usage.
Inside these groups, posts show black plastic packages with Royal Mail stickers, claiming to include new batches. One message stated: “It took eight of us to load them this morning.”
Customers can select between dry substance containers, mixed at residence with purified liquid, or pre-filled pens typically priced at £160 for 20mg. When questioned how much time a pen should last, vendors give contradictory answers varying between a several days to “depends on your body”.
A spokesperson for Telegram said it regularly moderated harmful material on its service including material that encouraged the “misuse of controlled medications”. The organization noted that it removed “millions of pieces of harmful content each day”.
“Individuals are injecting materials they cannot confirm. Although the science behind this drug is valid, these digital versions may not include what they advertise,” said a pharmacy expert, the head of pharmacy at a pharmacy service.
A medical professional of Asda Online Doctor connected the increase in demand to recent cost increases for authorized weight-loss drugs such as Mounjaro. “With prices increasing, patients are turning to online platforms. But fake injections are extremely dangerous. You can’t be certain what’s contained or whether the conditions they were made in was clean,” she explained.
Her staff has already seen individuals harmed by self-injection from unconfirmed suppliers. “We understand the disappointment, but buying from messaging apps or communication platforms is taking chances with your health,” said Wyllie. “These substances could be impure or improperly measured.”
A representative from the pharmaceutical company said retatrutide was in phase 3 research studies and had not been reviewed or authorized by any government authority anywhere in the world. “Consequently at this time no one can sell [it] for human use,” they explained, adding that any item “falsely representing itself as a Lilly experimental substance not yet approved … may subject users to potentially serious health risks”.
