An underground market for unapproved slimming medications is being driven by TikTok fitness influencers and sellers on messaging platforms, according to recent findings.

Investigational Treatment Gaining Traction Via Social Media

Retatrutide, which remains in clinical trials, is being promoted by social media influencers for its supposed fat-burning properties. Followers are urged to contact these profiles directly for supplier links, while also receiving discount codes.

Active Trade on Social Networks

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

Understanding Retatrutide

Retatrutide is an investigational injectable developed by American pharmaceutical company Eli Lilly. The drug targets three gut hormones – GLP-1, GIP and pancreatic hormone. Preliminary studies suggest it could assist patients lose up to 25% of their body weight. Referred to as the “triple G”, the substance is being promoted digitally as the successor to Ozempic.

Medical Professionals Express Worries

However, doctors and pharmacists have warned that the distribution of what remains an unapproved drug in the UK is a cause for concern and could lead to users injecting products of uncertain source.

Several professionals said the popularity for retatrutide could be linked to the rising price of licensed slimming treatments such as Mounjaro.

Legal Status and Enforcement

Selling retatrutide on TikTok or messaging apps is prohibited in the United Kingdom, as it is an unapproved medication that must not be promoted or distributed for personal consumption under the British medical regulations.

Several influencers try to circumvent the rules by referring to the substance as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a restricted substance, but promotion and distribution can still breach pharmaceutical, marketing, and consumer laws, potentially leading to fines, prosecution or imprisonment.

Service Reaction and Content Elimination

Based on TikTok, the platform has removed problematic material and prohibited related hashtags and query recommendations. The company said it was committed to maintaining the platform safe and allocating resources in enhancing compliance measures.

Digital Trading Operations

Research also found groups with up to 9,000 members selling retatrutide using the platform's integrated search feature, which functions like a public directory. Typing “retatrutide” instantly brings up groups with thousands of members, populated with images of slimming results, glowing testimonials and detailed instructions for mixing or administering at home.

Within minutes of joining one community, a vendor posted WhatsApp details, where most transactions occur. The seller provided an guidebook and promised shipping within 48 hours. When questioned whether the substance was authentic, one seller responded: “You can’t be sure.” Another shared a photo of a supposed testing documentation. Not one inquired about weight, health issues or past usage.

Item Details and Pricing

Within these communities, posts display dark colored packages with postal service labels, stating to contain fresh supplies. One communication stated: “It took eight of us to load them this morning.”

Buyers can choose between powder vials, prepared at residence with purified liquid, or ready-to-use injectors typically sold at £160 for 20mg. When asked how much time a pen should be used, sellers give conflicting answers varying between a few weeks to “depends on your body”.

Platform Moderation and Security Measures

A representative for Telegram said it actively monitored harmful material on its platform including material that encouraged the “misuse of controlled medications”. The company noted that it eliminated “millions of pieces of harmful content each day”.

Healthcare Expert Warnings

“Individuals are administering materials they cannot confirm. Even if the science behind this drug is valid, these digital versions may not contain what they claim,” said a pharmacy expert, the head of pharmacy at Chemist4U.

Dr Crystal Wyllie of Asda Online Doctor connected the increase in demand to current price rises for approved slimming drugs such as Mounjaro. “With costs rising, individuals are turning to social media. But counterfeit injections are highly risky. You cannot know what’s inside or whether the conditions they were made in was sterile,” she said.

Her team has already encountered individuals injured by self-injection from unconfirmed sources. “We recognize the frustration, but purchasing from messaging apps or communication platforms is taking chances with your well-being,” stated Wyllie. “These materials could be contaminated or improperly measured.”

Manufacturer Position

A spokesperson from Eli Lilly said retatrutide was in phase 3 research studies and had not been evaluated or approved by any regulatory agency globally. “Consequently at this point no one can sell [it] for personal consumption,” they said, noting that any item “falsely representing itself as a Lilly investigational substance not yet authorized … may subject users to potentially significant health risks”.
