An underground economy for unlicensed slimming medications is propelled by TikTok fitness influencers and vendors on communication apps, according to recent findings.
The experimental drug, which is still in research studies, is being promoted by social media influencers for its supposed fat-burning effects. Viewers are urged to message these accounts privately for supplier links, while also obtaining discount codes.
Separately, a robust market exists on messaging services, where groups with thousands of members share comparison photos, injection guides and claims of rapid British shipping. Sellers promote the drug there before redirecting customers to other platforms for transactions.
This medication is an investigational injectable developed by US drugmaker Eli Lilly. The treatment affects three gut hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Early trials suggest it could assist individuals lose up to 25% of their body weight. Referred to as the “triple G”, the drug is being promoted online as the successor to Ozempic.
Nevertheless, physicians and pharmacists have warned that the distribution of what remains an unlicensed drug in the UK is a cause for concern and could result in users injecting substances of unknown origin.
Some experts said the popularity for the experimental drug could be connected to the rising price of licensed weight loss products such as Mounjaro.
Selling retatrutide on TikTok or Telegram is prohibited in the UK, as it is an unapproved medication that must not be promoted or supplied for personal consumption under the Human Medicines Regulations 2012.
Several influencers attempt to circumvent the rules by calling to the drug as a “research chemical” or describing it as “not for human consumption”. The substance is not a restricted drug, but promotion and distribution can still breach medicines, marketing, and consumer laws, potentially leading to penalties, prosecution or prison.
Based on TikTok, the service has taken down violative material and prohibited related hashtags and search suggestions. The company said it was dedicated to maintaining the service secure and investing in strengthening compliance measures.
Research also found communities with up to nine thousand members selling the experimental drug using the platform's integrated search feature, which operates like a public directory. Typing “retatrutide” instantly brings up channels with numerous of members, filled with photos of slimming results, glowing testimonials and detailed guides for mixing or administering at home.
After moments of joining one community, a vendor posted WhatsApp details, where most transactions occur. The seller sent an instruction manual and guaranteed shipping within 48 hours. When questioned whether the substance was genuine, one seller said: “You can’t be sure.” Another shared a image of a supposed laboratory certificate. None asked about weight, medical conditions or previous experience.
Inside these communities, posts show dark colored parcels with postal service stickers, stating to include fresh supplies. One communication stated: “It took eight of us to load them this morning.”
Customers can select between powder vials, prepared at home with purified liquid, or pre-filled injectors usually sold at 160 pounds for 20 milligrams. When asked how long a pen should last, vendors give contradictory responses ranging from a several days to “depends on your body”.
A representative for the messaging service said it actively moderated dangerous material on its platform including material that encouraged the “misuse of controlled medications”. The organization noted that it removed “millions of pieces of harmful content each day”.
“People are administering substances they cannot confirm. Although the research behind retatrutide is valid, these online products may not contain what they advertise,” said Jason Murphy, the director of pharmaceutical services at a pharmacy service.
A medical professional of an online medical service linked the surge in interest to current price rises for authorized weight-loss drugs such as Mounjaro. “With costs increasing, individuals are turning to social media. But counterfeit treatments are highly risky. You can’t be certain what’s inside or whether the environment they were made in was sterile,” she said.
Her staff has already seen patients injured by self-injection from unverified sources. “We understand the frustration, but purchasing from Telegram or WhatsApp is taking chances with your health,” stated Wyllie. “These materials could be impure or incorrectly dosed.”
A representative from Eli Lilly said retatrutide was in third stage clinical trials and had not been reviewed or authorized by any regulatory agency globally. “Therefore at this point no one can market [it] for personal consumption,” they said, noting that any product “falsely representing itself as a Lilly investigational product not yet approved … may expose users to potentially significant medical dangers”.
