An underground economy for unlicensed slimming drugs is being driven by TikTok fitness influencers and vendors on messaging platforms, based on new investigations.

Experimental Treatment Gaining Popularity Online

Retatrutide, which is still in clinical trials, is being promoted by social media influencers for its supposed fat-burning properties. Followers are encouraged to contact these profiles directly for source information, while also obtaining discount codes.

Active Trade on Social Networks

Separately, a flourishing market exists on messaging services, where communities with thousands of participants share comparison images, administration instructions and claims of next-day British shipping. Vendors market the substance there before redirecting customers to other platforms for transactions.

Learning About The Experimental Drug

Retatrutide is an investigational injectable developed by American pharmaceutical company Eli Lilly. The drug targets three intestinal hormones – GLP-1, glucose-dependent insulinotropic polypeptide and glucagon. Early trials indicate it could help individuals lose up to 25% of their body weight. Referred to as the “triple G”, the drug is being promoted online as the next Ozempic.

Medical Professionals Voice Concerns

Nevertheless, physicians and pharmacists have cautions that the sale of what is still an unlicensed drug in the United Kingdom is worrisome and could lead to users injecting substances of uncertain source.

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

Regulatory Status and Enforcement

Marketing retatrutide on TikTok or Telegram is illegal in the United Kingdom, as it is an unlicensed medication that cannot be marketed or supplied for human use under the British medical regulations.

Some influencers attempt to sidestep the rules by referring to the substance as a “research chemical” or describing it as “not for human consumption”. The substance is not a restricted drug, but advertising and distribution can still breach pharmaceutical, advertising, and customer laws, potentially leading to fines, legal action or imprisonment.

Platform Reaction and Content Removal

According to the social media company, the platform has taken down problematic content and prohibited related hashtags and search suggestions. The company said it was committed to maintaining the service secure and investing in enhancing enforcement strategies.

Digital Trading Activities

Research also found groups with up to nine thousand participants selling the experimental drug using Telegram's integrated discovery tool, which functions like a online catalog. Entering “retatrutide” immediately displays groups with thousands of users, populated with photos of weight loss, positive testimonials and step-by-step guides for mixing or injecting at home.

After moments of entering one community, a vendor shared WhatsApp details, where most purchases occur. The seller provided an instruction manual and promised shipping within 48 hours. When asked whether the product was genuine, one seller said: “You can’t be sure.” Another shared a image of a alleged laboratory certificate. None inquired about weight, medical conditions or previous experience.

Item Details and Costs

Within these groups, messages show dark colored parcels with Royal Mail labels, claiming to include fresh supplies. One communication read: “It took eight of us to load them this morning.”

Customers can select between powder vials, mixed at residence with purified liquid, or pre-filled pens typically sold at 160 pounds for 20 milligrams. When asked how much time a pen should last, vendors give conflicting responses varying between a several days to “depends on your body”.

Service Moderation and Safety Actions

A spokesperson for Telegram stated it regularly monitored harmful content on its service including content that encouraged the “misuse of controlled medications”. The company added that it eliminated “millions of pieces of harmful content each day”.

Medical Expert Cautions

“People are injecting materials they can’t verify. Although the research behind this drug is sound, these digital products may not contain what they claim,” said a pharmacy expert, 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 prices increasing, individuals are using social media. But fake injections are extremely risky. You cannot know what’s inside or whether the conditions they were made in was sterile,” she said.

Her staff has already seen patients injured by personal administration from unverified sources. “We recognize the frustration, but purchasing from messaging apps or WhatsApp is taking chances with your health,” said the doctor. “These materials could be impure or improperly measured.”

Manufacturer Position

A spokesperson from the pharmaceutical company said the substance was in phase 3 research studies and had not been evaluated or approved by any government authority globally. “Therefore at this time no one can sell [it] for personal consumption,” they said, noting that any product “falsely representing itself as a Lilly investigational product not yet approved … may subject users to potentially significant medical dangers”.
