An underground market for unlicensed slimming medications is being driven by social media fitness personalities and vendors on communication apps, based on recent findings.
Retatrutide, which is still in clinical trials, is being advertised by social media influencers for its supposed fat-burning effects. Viewers are urged to message these accounts privately for supplier links, while also receiving discount codes.
Additionally, a robust market exists on messaging services, where communities with thousands of members share “before and after” photos, injection guides and claims of rapid British shipping. Sellers promote the substance there before redirecting buyers to WhatsApp for transactions.
This medication is an investigational injection created by US drugmaker Eli Lilly. The treatment affects three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Early trials suggest it could assist individuals reduce up to a quarter of their body weight. Nicknamed the “triple G”, the drug is being hailed digitally as the successor to Ozempic.
Nevertheless, physicians and pharmacists have warned that the distribution of what remains an unapproved drug in the UK is a cause for concern and could result in individuals injecting products of uncertain source.
Some experts stated the popularity for retatrutide could be linked to the rising price of approved weight loss treatments such as Mounjaro.
Marketing the unapproved drug on social media or Telegram is prohibited in the UK, as it is an unlicensed drug that must not be promoted or distributed for human use under the Human Medicines Regulations 2012.
Several content creators try to sidestep the rules by referring to the substance as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a controlled substance, but advertising and distribution can still violate medicines, marketing, and customer laws, risking fines, prosecution or prison.
Based on TikTok, the service has removed problematic material and banned related hashtags and query recommendations. The organization stated it was dedicated to maintaining the platform secure and investing in strengthening enforcement strategies.
Research also discovered communities with up to 9,000 participants marketing retatrutide using Telegram's built-in discovery tool, which functions like a online catalog. Entering “retatrutide” immediately brings up channels with thousands of users, filled with photos of slimming results, positive testimonials and step-by-step guides for mixing or injecting at residence.
After minutes of joining one community, a seller posted WhatsApp details, where most transactions take place. The vendor provided an instruction manual and promised shipping within two days. When questioned whether the product was authentic, one vendor responded: “You can’t be sure.” Another provided a image of a supposed laboratory certificate. Not one asked about weight, health issues or previous experience.
Inside these groups, messages show dark colored packages with Royal Mail stickers, stating to include new batches. One communication stated: “It took eight of us to load them this morning.”
Customers can select between dry substance containers, mixed at home with purified liquid, or ready-to-use injectors typically sold at £160 for 20mg. When questioned how long a pen should last, vendors give contradictory responses ranging from a few weeks to “depends on your body”.
A spokesperson for Telegram stated it regularly monitored dangerous material on its service including content that encouraged the “misuse of controlled medications”. The company added that it removed “millions of pieces of harmful content each day”.
“People are injecting materials they cannot confirm. Even if the science behind retatrutide is valid, these online versions may not include what they advertise,” said Jason Murphy, the head of pharmacy at a pharmacy service.
A medical professional of an online medical service linked the increase in interest to current price rises for approved weight-loss drugs such as Mounjaro. “With costs increasing, individuals 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 explained.
Her staff has already encountered individuals injured by personal administration from unconfirmed suppliers. “We recognize the disappointment, but purchasing from messaging apps or communication platforms is taking chances with your well-being,” stated Wyllie. “These materials could be impure or improperly measured.”
A spokesperson from the pharmaceutical company said the substance was in phase 3 research studies and had not been evaluated or approved 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 company experimental product not yet approved … may expose patients to possibly serious medical dangers”.
