An underground market for unlicensed weight-loss medications is being driven by TikTok fitness influencers and sellers on messaging platforms, according to new investigations.
The experimental drug, which remains in clinical trials, is being advertised by social media influencers for its supposed fat-burning effects. Followers are encouraged to contact these profiles privately for source information, while also receiving promotional offers.
Separately, a flourishing trade exists on Telegram, where groups with thousands of members share “before and after” images, injection guides and assertions of next-day British shipping. Vendors market the drug there before directing buyers to other platforms for purchases.
Retatrutide is an investigational injection created by American pharmaceutical company Eli Lilly. The treatment targets three intestinal hormones – GLP-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Early trials suggest it could assist individuals lose up to 25% of their total weight. Referred to as the “triple G”, the substance is being promoted online as the successor to Ozempic.
However, doctors and pharmacists have warned that the sale of what is still an unlicensed drug in the UK is a cause for concern and could result in individuals injecting substances of uncertain source.
Several professionals said the demand for the experimental drug could be connected to the rising cost of approved weight loss treatments such as Mounjaro.
Selling retatrutide on TikTok or Telegram is illegal in the UK, as it is an unapproved drug that cannot be marketed or supplied for human use under the British medical regulations.
Some influencers attempt to circumvent the regulations by calling to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a restricted drug, but advertising and supply can still violate medicines, marketing, and customer regulations, risking penalties, prosecution or imprisonment.
According to the social media company, the service has taken down violative content and banned associated hashtags and search suggestions. The organization stated it was committed to maintaining the service safe and investing in enhancing compliance measures.
Investigations also found communities with up to nine thousand participants selling the experimental drug using Telegram's integrated search feature, which operates like a online catalog. Typing “retatrutide” immediately brings up channels with numerous of users, populated with images of weight loss, positive reviews and detailed instructions for preparing or administering at residence.
Within minutes of joining one group, a vendor shared WhatsApp details, where most transactions occur. The vendor provided an instruction manual and promised delivery within two days. When asked whether the substance was genuine, one seller said: “You can’t be sure.” Another provided a photo of a supposed laboratory certificate. Not one inquired about body mass, health issues or past usage.
Within these groups, posts show dark colored packages with Royal Mail stickers, claiming to include new batches. One communication read: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, mixed at residence with sterile water, or pre-filled pens usually priced at 160 pounds for 20 milligrams. When questioned how much time a injector should last, vendors give contradictory answers varying between a few weeks to “depends on your body”.
A representative for the messaging service stated it actively monitored harmful content on its service including material that promoted the “misuse of controlled medications”. The company added that it removed “millions of pieces of harmful content each day”.
“People are injecting materials they can’t verify. Although the science behind this drug is valid, these online products may not contain what they claim,” said Jason Murphy, the head of pharmaceutical services at Chemist4U.
A medical professional of Asda Online Doctor connected the surge in interest to current price rises for authorized slimming drugs such as Mounjaro. “With costs rising, individuals are using social media. But fake treatments are extremely risky. You cannot know what’s inside or whether the environment they were produced in was clean,” she said.
Her staff has previously encountered patients harmed by self-injection from unconfirmed sources. “We understand the frustration, but buying from messaging apps or communication platforms is gambling with your well-being,” said Wyllie. “These materials could be contaminated or incorrectly dosed.”
A representative from the pharmaceutical company stated retatrutide was in phase 3 research studies and had not been evaluated or authorized by any government authority anywhere in the world. “Therefore at this time no one can sell [it] for personal consumption,” they said, adding that any product “misleadingly claiming itself as a company experimental substance not yet authorized … may expose users to possibly significant health risks”.
