An underground economy for unlicensed weight-loss medications is being driven by TikTok fitness influencers and sellers on messaging platforms, according to recent findings.
Experimental Drug Gaining Traction Via Social Media
The experimental drug, which is still in research studies, is being promoted by online personalities for its supposed weight-reducing properties. Followers are urged to message these accounts privately for source information, while also receiving promotional offers.
Active Trade on Messaging Platforms
Additionally, a robust trade exists on messaging services, where groups with thousands of participants share comparison photos, injection guides and assertions of rapid British shipping. Vendors promote the drug there before redirecting customers to WhatsApp for purchases.
Understanding Retatrutide
This medication is an investigational injectable created by US drugmaker Eli Lilly. The drug affects three gut hormones – glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide and glucagon. Preliminary studies indicate it could help patients reduce up to a quarter of their body weight. Referred to as the “triple G”, the substance is being hailed digitally as the successor to Ozempic.
Healthcare Experts Express Worries
However, physicians and chemists have cautions that the distribution of what is still an unapproved medication in the United Kingdom is a cause for concern and could lead to individuals injecting substances of uncertain source.
Several experts said the demand for retatrutide could be linked to the rising cost of approved slimming products such as Mounjaro.
Legal Status and Enforcement
Selling retatrutide on TikTok or Telegram is illegal in the UK, as it is an unlicensed drug that cannot be promoted or supplied for human use 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 controlled drug, but promotion and distribution can still violate medicines, marketing, and customer laws, risking fines, legal action or prison.
Service Response and Content Removal
According to the social media company, the platform has taken down problematic content and prohibited related keywords and search suggestions. The company said it was dedicated to maintaining the service safe and investing in strengthening enforcement strategies.
Digital Marketplace Activities
Investigations also discovered groups with up to 9,000 members selling retatrutide using Telegram's integrated search feature, which functions like a public directory. Typing “retatrutide” instantly displays channels with thousands of users, populated with images of weight loss, glowing testimonials and step-by-step guides for mixing or injecting at home.
Within minutes of entering one community, a seller shared WhatsApp details, where the majority of purchases occur. The seller provided an guidebook and promised delivery within 48 hours. When questioned whether the substance was genuine, one seller said: “You can’t be sure.” Another shared a photo of a alleged laboratory certificate. Not one asked about body mass, medical conditions or previous experience.
Item Information and Pricing
Within these communities, posts display dark colored packages with postal service stickers, claiming to contain fresh supplies. One message stated: “It took eight of us to load them this morning.”
Buyers can select between powder vials, prepared at home with sterile water, or ready-to-use pens usually sold at £160 for 20mg. When asked how long a injector should last, sellers give conflicting responses varying between a several days to “depends on your body”.
Service Oversight and Security Actions
A spokesperson for Telegram stated it actively moderated dangerous material on its platform including material that promoted the “misuse of controlled medications”. The company noted that it eliminated “millions of pieces of harmful content each day”.
Medical Professional Warnings
“People are injecting materials they cannot confirm. Although the research behind this drug is valid, these online products may not contain what they claim,” stated a pharmacy expert, the head of pharmacy at Chemist4U.
Dr Crystal Wyllie of an online medical service linked the increase in demand to recent cost increases for approved slimming medications such as Mounjaro. “With prices increasing, individuals are turning to online platforms. But fake injections are highly risky. You can’t be certain what’s inside or whether the environment they were produced in was sterile,” she explained.
Her team has previously seen patients injured by personal administration from unconfirmed sources. “We understand the frustration, but buying from Telegram or communication platforms is gambling with your well-being,” said Wyllie. “These materials could be impure or improperly measured.”
Manufacturer Statement
A representative from Eli Lilly said the substance was in phase 3 research studies and had not been reviewed or authorized by any government authority anywhere in the world. “Therefore at this point no one can sell [it] for human use,” they said, adding that any item “misleadingly claiming itself as a Lilly experimental substance not yet approved … may subject patients to possibly significant medical dangers”.
