Several professionals stated the popularity for retatrutide could be linked to the rising cost of approved slimming treatments such as Mounjaro.

Selling retatrutide on TikTok or messaging apps is illegal in the UK, as it is an unlicensed drug that cannot be promoted or supplied for human use under the Human Medicines Regulations 2012.

After moments of entering one group, a vendor shared contact information, where most transactions take place. The vendor sent an instruction manual and guaranteed shipping within 48 hours. When questioned whether the substance was genuine, one seller responded: “You can’t be sure.” Another provided a photo of a alleged testing documentation. Not one asked about weight, health issues or previous experience.

Platform Oversight and Security Measures

A spokesperson for the messaging service said it actively monitored harmful content on its service including content that encouraged the “misuse of controlled medications”. The organization added that it removed “millions of pieces of harmful content each day”.

Medical Expert Warnings

“People are injecting substances they cannot confirm. Although the research behind retatrutide is valid, these online products may not contain what they claim,” said a pharmacy expert, the director of pharmacy at a pharmacy service.

Dr Crystal Wyllie of Asda Online Doctor linked the surge in demand to current cost increases for approved slimming drugs such as Mounjaro. “With prices rising, patients are using social media. But counterfeit treatments are highly dangerous. You cannot know what’s inside or whether the environment they were produced in was clean,” she said.

Her staff has already encountered individuals harmed by personal administration from unconfirmed sources. “We understand the disappointment, but buying from messaging apps or WhatsApp is taking chances with your health,” stated the doctor. “These substances could be impure or incorrectly dosed.”

Manufacturer Statement

A representative from the pharmaceutical company stated retatrutide was in third stage research studies and had not been reviewed or authorized by any regulatory agency anywhere in the world. “Therefore at this time no one can sell [it] for personal consumption,” they said, noting that any product “misleadingly claiming itself as a company investigational product not yet authorized … may subject users to possibly serious medical dangers”.
