An underground economy for unlicensed weight-loss medications is being driven by social media fitness personalities and vendors on messaging platforms, according to new investigations.
Experimental Treatment Gaining Traction Via Social Media
The experimental drug, which is still in clinical trials, is being promoted by online personalities for its supposed weight-reducing properties. Followers are urged to message these accounts directly for supplier links, while also obtaining discount codes.
Active Commerce on Messaging Platforms
Separately, a robust market exists on messaging services, where groups with thousands of members share “before and after” images, administration instructions and claims of rapid UK delivery. Sellers market the drug there before redirecting customers to other platforms for purchases.
Understanding Retatrutide
Retatrutide is an experimental injection developed by American pharmaceutical company Eli Lilly. The drug targets three gut hormones – glucagon-like peptide-1, GIP and glucagon. Preliminary studies indicate it could help patients lose up to 25% of their total weight. Referred to as the “triple G”, the drug is being promoted online as the successor to Ozempic.
Healthcare Experts Voice Concerns
However, physicians and pharmacists have warned that the sale of what remains an unlicensed drug in the UK is a cause for concern and could result in individuals injecting products of uncertain source.
Some professionals said the popularity for the experimental drug could be connected to the increasing cost of approved slimming treatments such as Mounjaro.
Regulatory Position and Enforcement
Marketing retatrutide on TikTok or Telegram is prohibited in the UK, as it is an unlicensed medication that must not be promoted or supplied for personal consumption under the Human Medicines Regulations 2012.
Several content creators attempt to circumvent the regulations by referring to the substance as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a restricted drug, but advertising and distribution can still violate pharmaceutical, marketing, and consumer regulations, risking fines, legal action or prison.
Service Reaction and Material Removal
According to TikTok, the service has removed problematic content and prohibited related keywords and search suggestions. The company stated it was dedicated to keeping the service secure and investing in enhancing enforcement strategies.
Digital Trading Activities
Research also found communities with up to 9,000 members selling retatrutide using Telegram's built-in search feature, which functions like a public directory. Entering “retatrutide” instantly brings up groups with thousands of members, populated with photos of weight loss, glowing testimonials and step-by-step instructions for preparing or administering at residence.
Within moments of joining one group, a vendor posted contact information, where most purchases take place. The vendor provided an guidebook and guaranteed delivery within 48 hours. When questioned whether the product was genuine, one seller said: “You can’t be sure.” Another provided a photo of a alleged testing documentation. None asked about weight, health issues or past usage.
Product Details and Costs
Within these groups, posts show black plastic packages with Royal Mail stickers, stating to contain fresh supplies. One communication stated: “It took eight of us to load them this morning.”
Customers can choose between dry substance containers, prepared at residence with purified liquid, or ready-to-use pens typically sold at £160 for 20mg. When questioned how long a injector should be used, vendors give conflicting responses ranging from a several days to “depends on your body”.
Platform Oversight and Safety Actions
A spokesperson for the messaging service said it regularly moderated dangerous material on its platform including material that promoted the “misuse of controlled medications”. The organization noted that it removed “millions of pieces of harmful content each day”.
Medical Professional Cautions
“Individuals are injecting substances they can’t verify. Even if the science behind retatrutide is sound, these online versions may not include what they advertise,” stated Jason Murphy, the head of pharmaceutical services at Chemist4U.
A medical professional of an online medical service connected the surge in interest to current price rises for authorized slimming drugs such as Mounjaro. “With costs increasing, individuals are using online platforms. But counterfeit treatments are extremely risky. You cannot know what’s inside or whether the environment they were made in was clean,” she said.
Her team has already encountered individuals harmed by self-injection from unverified sources. “We understand the frustration, but purchasing from messaging apps or WhatsApp is taking chances with your well-being,” stated the doctor. “These materials could be impure or incorrectly dosed.”
Manufacturer Statement
A spokesperson from Eli Lilly said the substance was in phase 3 research studies and had not been evaluated or approved by any government authority anywhere in the world. “Therefore at this point no one can sell [it] for personal consumption,” they said, adding that any item “misleadingly claiming itself as a Lilly investigational substance not yet approved … may subject patients to possibly significant health risks”.
