A shadow market for unapproved slimming medications is being driven by TikTok fitness influencers and vendors on communication apps, according to recent findings.
The experimental drug, which is still in clinical trials, is being advertised by social media influencers for its supposed fat-burning properties. Followers are encouraged to message these profiles privately for supplier links, while also obtaining discount codes.
Separately, a flourishing trade exists on Telegram, where groups with numerous of participants share “before and after” photos, injection guides and claims of rapid UK delivery. Sellers promote the substance there before directing buyers to other platforms for purchases.
Retatrutide is an investigational injectable created by American pharmaceutical company Eli Lilly. The drug affects three intestinal hormones – GLP-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Early trials indicate it could help patients reduce up to 25% of their body weight. Referred to as the “triple G”, the drug is being promoted digitally as the next Ozempic.
However, physicians and pharmacists have warned that the distribution of what remains an unlicensed medication in the UK is a cause for concern and could result in individuals administering substances of unknown origin.
Several experts said the demand for the experimental drug could be connected to the rising cost of approved slimming products such as Mounjaro.
Marketing retatrutide on TikTok or Telegram is illegal in the United Kingdom, as it is an unapproved medication that must not be marketed or distributed for human use under the British medical regulations.
Some content creators try to circumvent the rules 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 distribution can still breach medicines, advertising, and customer laws, potentially leading to penalties, legal action or prison.
According to the social media company, the service has taken down violative content and banned associated keywords and search suggestions. The company stated it was committed to keeping the platform secure and allocating resources in enhancing compliance measures.
Investigations also found communities with up to 9,000 participants marketing retatrutide using the platform's integrated discovery tool, which operates like a online catalog. Typing “retatrutide” immediately brings up groups with numerous of members, filled with photos of slimming results, glowing reviews and step-by-step instructions for mixing or injecting at home.
After minutes of joining one group, a seller shared contact information, where the majority of purchases take place. The seller sent an instruction manual and promised shipping within two days. When asked whether the product was genuine, one seller said: “You can’t be sure.” Another shared a image of a alleged laboratory certificate. Not one inquired about weight, health issues or past usage.
Within these groups, posts display black plastic parcels with Royal Mail stickers, stating to include new batches. One communication stated: “It took eight of us to load them this morning.”
Buyers can choose between powder vials, mixed at residence with sterile water, or ready-to-use pens usually sold at 160 pounds for 20 milligrams. When questioned how long a pen should last, sellers give conflicting answers varying between a several days to “depends on your body”.
A spokesperson for the messaging service stated it actively monitored dangerous content on its service including content that promoted the “misuse of controlled medications”. The organization added that it eliminated “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 versions may not contain what they claim,” said Jason Murphy, the head of pharmaceutical services at a pharmacy service.
Dr Crystal Wyllie of an online medical service linked the increase in interest to recent cost increases for approved slimming drugs such as Mounjaro. “With prices increasing, patients are using social media. But counterfeit treatments are extremely risky. You can’t be certain what’s inside or whether the conditions they were made in was clean,” she said.
Her team has previously seen patients harmed by self-injection from unconfirmed suppliers. “We recognize the disappointment, but buying from Telegram or WhatsApp is taking chances with your well-being,” stated the doctor. “These materials could be contaminated or improperly measured.”
A representative from the pharmaceutical company stated retatrutide was in phase 3 research studies and had not been evaluated or approved by any regulatory agency globally. “Consequently at this time no one can market [it] for human use,” they said, adding that any product “falsely representing itself as a Lilly investigational product not yet approved … may expose users to potentially serious health risks”.
