An underground market for unapproved weight-loss medications is being driven by TikTok fitness influencers and sellers on messaging platforms, based on recent findings.
Retatrutide, which is still in research studies, is being promoted by social media influencers for its supposed fat-burning properties. Followers are urged to message these profiles directly for supplier links, while also obtaining promotional offers.
Additionally, a robust trade exists on messaging services, where groups with thousands of members share “before and after” photos, injection guides and assertions of rapid British shipping. Vendors market the substance there before directing customers to other platforms for transactions.
Retatrutide is an experimental injectable developed by US drugmaker Eli Lilly. The drug affects three gut hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Preliminary studies suggest it could assist individuals lose up to 25% of their body weight. Nicknamed the “triple G”, the drug is being promoted online as the successor to Ozempic.
Nevertheless, doctors and pharmacists have warned that the sale of what remains an unapproved medication in the UK is worrisome and could result in users administering substances of unknown origin.
Several professionals stated the popularity for retatrutide could be linked to the rising price of licensed weight loss products such as Mounjaro.
Marketing retatrutide on social media or Telegram is prohibited in the United Kingdom, as it is an unlicensed medication that cannot be marketed or distributed for personal consumption under the Human Medicines Regulations 2012.
Several influencers attempt to sidestep the rules by calling to the substance as a “research chemical” or describing it as “not for human consumption”. The substance is not a controlled substance, but advertising and distribution can still violate pharmaceutical, advertising, and customer regulations, risking fines, prosecution or imprisonment.
Based on the social media company, the service has taken down violative content and prohibited associated hashtags and query recommendations. The company said it was committed to maintaining the platform secure and investing in strengthening enforcement strategies.
Investigations also discovered communities with up to nine thousand members marketing the experimental drug using Telegram's built-in discovery tool, which operates like a public directory. Entering “retatrutide” immediately brings up groups with thousands of members, populated with photos of slimming results, glowing testimonials and step-by-step guides for preparing or administering at residence.
Within moments of joining one community, a seller posted WhatsApp details, where most transactions take place. The vendor sent an guidebook and promised shipping within 48 hours. When asked whether the substance was authentic, one vendor responded: “You can’t be sure.” Another shared a image of a alleged laboratory certificate. Not one inquired about body mass, health issues or past usage.
Within these communities, posts display black plastic packages with postal service labels, claiming to include fresh supplies. One message 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 injectors usually sold at 160 pounds for 20 milligrams. When asked how much time a pen should last, sellers give conflicting answers varying between a few weeks to “depends on your body”.
A spokesperson for the messaging service stated it regularly moderated harmful material on its platform including content that encouraged the “misuse of controlled medications”. The company added that it removed “millions of pieces of harmful content each day”.
“People are administering materials they cannot confirm. Even if the science behind this drug is valid, these online versions may not contain what they claim,” said a pharmacy expert, the director of pharmaceutical services at Chemist4U.
Dr Crystal Wyllie of an online medical service linked the increase in demand to current price rises for approved slimming medications such as Mounjaro. “With prices rising, individuals are turning to online platforms. But counterfeit injections are highly risky. You cannot know what’s contained or whether the conditions they were made in was sterile,” she explained.
Her team has already seen patients injured by self-injection from unverified suppliers. “We understand the disappointment, but purchasing from messaging apps or WhatsApp is gambling with your health,” stated Wyllie. “These substances could be impure or improperly measured.”
A spokesperson from Eli Lilly said the substance was in third stage clinical trials and had not been reviewed or authorized by any government authority globally. “Consequently at this point no one can market [it] for human use,” they said, noting that any item “misleadingly claiming itself as a company experimental product not yet approved … may subject users to potentially serious medical dangers”.
