A shadow market for unlicensed weight-loss drugs is being driven by TikTok fitness influencers and sellers on communication apps, based on new investigations.

Experimental Drug Acquiring Popularity Online

The experimental drug, which is still in clinical trials, is being promoted by online personalities for its alleged fat-burning properties. Followers are urged to contact these profiles directly for source information, while also obtaining promotional offers.

Thriving Trade on Social Networks

Additionally, a flourishing market exists on messaging services, where groups with thousands of members share comparison photos, injection guides and claims of next-day UK delivery. Vendors market the drug there before redirecting buyers to WhatsApp for transactions.

Understanding Retatrutide

Retatrutide is an experimental injectable created by American pharmaceutical company Eli Lilly. The drug targets three intestinal hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials suggest it could assist patients reduce up to a quarter of their total weight. Nicknamed the “triple G”, the drug is being promoted digitally as the next Ozempic.

Healthcare Professionals Express Concerns

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

Several experts stated the popularity for the experimental drug could be linked to the increasing price of licensed weight loss treatments such as Mounjaro.

Regulatory Status and Implementation

Marketing the unapproved drug on TikTok or Telegram is prohibited in the United Kingdom, as it is an unlicensed medication that cannot be promoted or distributed for personal consumption under the British medical regulations.

Some influencers attempt to sidestep 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 advertising and distribution can still breach pharmaceutical, marketing, and consumer regulations, risking fines, prosecution or imprisonment.

Platform Response and Content Removal

Based on the social media company, the service has removed violative content and banned associated keywords and query recommendations. The organization stated it was dedicated to maintaining the service secure and allocating resources in enhancing enforcement strategies.

Digital Trading Operations

Investigations also discovered communities with up to nine thousand participants marketing retatrutide using Telegram's integrated search feature, which functions like a online catalog. Entering “retatrutide” immediately displays channels with thousands of members, filled with photos of weight loss, glowing reviews and detailed guides for preparing or injecting at home.

After moments of entering one community, a seller shared contact information, where the majority of purchases occur. The seller sent an instruction manual and promised shipping within two days. When asked whether the product was authentic, one vendor responded: “You can’t be sure.” Another shared a image of a supposed testing documentation. None asked about weight, medical conditions or previous experience.

Item Information and Pricing

Inside these communities, posts show dark colored parcels with postal service labels, stating to contain new batches. One communication stated: “It took eight of us to load them this morning.”

Buyers can choose between dry substance containers, prepared at home with sterile water, or ready-to-use pens typically sold at £160 for 20mg. When questioned how much time a pen should be used, sellers give conflicting answers ranging from a several days to “depends on your body”.

Platform Moderation and Security Measures

A spokesperson for Telegram said it regularly monitored harmful content on its platform including material that promoted the “misuse of controlled medications”. The organization added that it removed “millions of pieces of harmful content each day”.

Healthcare Professional Warnings

“Individuals are administering materials they can’t verify. Even if the science behind retatrutide is valid, these online products may not include what they claim,” stated a pharmacy expert, the director of pharmacy at Chemist4U.

Dr Crystal Wyllie of an online medical service linked the surge in demand to current cost increases for authorized weight-loss medications such as Mounjaro. “With prices increasing, individuals are turning to online platforms. But counterfeit treatments are extremely risky. You cannot know what’s contained or whether the conditions they were produced in was clean,” she said.

Her team has already seen individuals injured by self-injection from unverified sources. “We understand the frustration, but buying from Telegram or WhatsApp is gambling with your health,” said the doctor. “These substances could be impure or incorrectly dosed.”

Manufacturer Position

A spokesperson from the pharmaceutical company said the substance was in phase 3 research studies and had not been reviewed or approved by any government authority globally. “Therefore at this point no one can sell [it] for human use,” they explained, adding that any product “falsely representing itself as a Lilly investigational substance not yet authorized … may expose patients to potentially significant medical dangers”.
