An underground economy for unlicensed slimming drugs is being driven by TikTok fitness influencers and vendors on communication apps, based on recent findings.

Investigational Treatment Acquiring Traction Via Social Media

Retatrutide, which is still in clinical trials, is being advertised by social media influencers for its supposed weight-reducing properties. Followers are encouraged to contact these profiles directly for supplier links, while also receiving promotional offers.

Active Commerce on Messaging Platforms

Additionally, a robust trade exists on messaging services, where communities with thousands of members share “before and after” photos, injection guides and claims of next-day UK delivery. Sellers market the substance there before directing buyers to WhatsApp for transactions.

Learning About Retatrutide

Retatrutide is an experimental injection developed by American pharmaceutical company Eli Lilly. The drug targets three gut hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials indicate 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.

Healthcare Professionals Voice Worries

Nevertheless, doctors and pharmacists have cautions that the sale of what is still an unapproved medication in the United Kingdom is a cause for concern and could result in users administering substances of unknown origin.

Several professionals said the popularity for the experimental drug could be connected to the increasing cost of licensed weight loss treatments such as Mounjaro.

Regulatory Status and Enforcement

Marketing the unapproved drug on social media or messaging apps is prohibited in the UK, as it is an unapproved drug that must not be promoted or supplied for personal consumption under the Human Medicines Regulations 2012.

Several content creators try to circumvent the rules by referring to the drug as a “research chemical” or citing it as “not for human consumption”. The substance is not a restricted drug, but promotion and distribution can still violate medicines, marketing, and consumer regulations, potentially leading to penalties, prosecution or prison.

Service Reaction and Material Removal

Based on TikTok, the platform has removed problematic content and banned related keywords and query recommendations. The organization said it was dedicated to maintaining the platform safe and investing in strengthening enforcement strategies.

Online Marketplace Activities

Investigations also found communities with up to nine thousand participants selling retatrutide using the platform's integrated search feature, which operates like a public directory. Typing “retatrutide” immediately displays groups with thousands of members, filled with photos of slimming results, positive testimonials and step-by-step guides for mixing or administering at home.

Within moments of entering one group, a seller posted WhatsApp details, where the majority of transactions take place. The seller provided an instruction manual and promised delivery within 48 hours. When questioned whether the product was genuine, one vendor said: “You can’t be sure.” Another provided a photo of a supposed laboratory certificate. Not one inquired about body mass, medical conditions or previous experience.

Product Details and Pricing

Within these groups, posts display dark colored parcels with postal service stickers, claiming to include new batches. One communication read: “It took eight of us to load them this morning.”

Buyers can choose between powder vials, mixed at home with sterile water, or ready-to-use pens usually sold at 160 pounds for 20mg. When questioned how long a pen should be used, sellers give conflicting responses ranging from a several days to “depends on your body”.

Service Oversight and Safety Measures

A spokesperson for Telegram stated it actively moderated harmful content 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”.

Healthcare Professional Warnings

“People are administering materials they can’t verify. Although the science behind this drug is sound, these online products may not contain what they claim,” stated a pharmacy expert, the director of pharmacy at a pharmacy service.

A medical professional of Asda Online Doctor linked the surge in demand to recent cost increases for approved slimming medications such as Mounjaro. “With costs rising, patients are turning to social media. But fake treatments are extremely risky. You can’t be certain what’s inside or whether the environment they were made in was clean,” she explained.

Her staff has already encountered patients harmed by self-injection from unverified sources. “We recognize the disappointment, but purchasing from Telegram or communication platforms is gambling with your well-being,” said Wyllie. “These materials could be impure or incorrectly dosed.”

Producer Statement

A representative from the pharmaceutical company said retatrutide was in phase 3 clinical trials and had not been evaluated or approved by any government authority globally. “Therefore at this time no one can sell [it] for human use,” they said, noting that any product “misleadingly claiming itself as a Lilly experimental substance not yet authorized … may expose users to potentially significant medical dangers”.
