An underground economy for unlicensed slimming medications is being driven by TikTok fitness influencers and vendors on communication apps, according to recent findings.
Retatrutide, which is still in clinical trials, is being promoted by social media influencers for its supposed weight-reducing effects. Followers are urged to message these accounts privately for source information, while also obtaining discount codes.
Additionally, a robust trade exists on Telegram, where communities with numerous of participants share comparison photos, injection guides and claims of next-day British shipping. Sellers promote the drug there before directing buyers to WhatsApp for transactions.
Retatrutide is an experimental injection created by US drugmaker Eli Lilly. The drug targets three intestinal hormones – GLP-1, GIP and pancreatic hormone. Early trials suggest it could assist patients lose up to 25% of their total weight. Referred to as the “triple G”, the substance is being promoted digitally as the next Ozempic.
Nevertheless, physicians and pharmacists have warned that the sale of what remains an unapproved medication in the UK is worrisome and could result in users injecting products of unknown origin.
Several experts said the popularity for retatrutide could be linked to the increasing cost of licensed slimming products such as Mounjaro.
Selling the unapproved drug on TikTok or Telegram is prohibited in the UK, as it is an unapproved drug that must not be marketed or supplied for personal consumption under the British medical regulations.
Several influencers attempt to circumvent the regulations by calling to the substance as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a restricted drug, but promotion and distribution can still violate medicines, advertising, and consumer regulations, risking penalties, legal action or prison.
According to the social media company, the platform has taken down violative material and banned related hashtags and search suggestions. The company said it was dedicated to keeping the service safe and investing in strengthening enforcement strategies.
Research also found groups with up to nine thousand participants selling retatrutide using Telegram's integrated search feature, which functions like a public directory. Typing “retatrutide” instantly displays channels with numerous of users, filled with photos of slimming results, glowing testimonials and detailed instructions for preparing or injecting at residence.
After minutes 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 said: “You can’t be sure.” Another provided a image of a supposed testing documentation. Not one inquired about body mass, medical conditions or past usage.
Inside these groups, posts display black plastic parcels with Royal Mail stickers, 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 home with sterile water, or ready-to-use pens usually priced at £160 for 20mg. When asked how long a injector should be used, sellers give conflicting answers varying between a several days to “depends on your body”.
A spokesperson for Telegram said it regularly moderated harmful material on its platform including content that promoted the “misuse of controlled medications”. The organization noted that it removed “millions of pieces of harmful content each day”.
“People are injecting substances they cannot confirm. Although the research behind this drug is sound, these digital products may not contain what they advertise,” said a pharmacy expert, the head of pharmaceutical services at a pharmacy service.
A medical professional of Asda Online Doctor connected the surge in interest to recent price rises for authorized weight-loss drugs such as Mounjaro. “With prices increasing, patients are using social media. But counterfeit treatments are highly dangerous. You can’t be certain what’s inside or whether the environment they were produced in was clean,” she explained.
Her team has previously encountered individuals injured by self-injection from unconfirmed sources. “We recognize the disappointment, but purchasing from Telegram or WhatsApp is gambling with your well-being,” said the doctor. “These materials could be impure or improperly measured.”
A representative from Eli Lilly said retatrutide was in third stage research studies and had not been evaluated or authorized by any government authority globally. “Therefore at this time no one can market [it] for personal consumption,” they explained, adding that any item “falsely representing itself as a Lilly experimental product not yet authorized … may expose users to potentially significant medical dangers”.
