A shadow market for unapproved slimming drugs is being driven by social media fitness personalities and sellers on communication apps, based on new investigations.

Investigational Drug Acquiring Popularity Via Social Media

The experimental drug, which is still in clinical trials, is being advertised by online personalities for its alleged weight-reducing properties. Viewers are encouraged to contact these profiles directly for source information, while also obtaining promotional offers.

Active Trade on Social Networks

Separately, a flourishing market exists on messaging services, where communities with thousands of members share comparison photos, injection guides and assertions of next-day British shipping. Vendors market the substance there before directing customers to WhatsApp for purchases.

Learning About Retatrutide

This medication is an investigational injectable developed by American pharmaceutical company Eli Lilly. The drug targets three gut hormones – glucagon-like peptide-1, GIP and glucagon. Preliminary studies suggest it could help individuals reduce up to a quarter of their total weight. Referred to as the “triple G”, the drug is being hailed online as the next Ozempic.

Healthcare Professionals Voice Worries

Nevertheless, physicians and pharmacists have cautions that the distribution of what remains an unapproved medication in the UK is worrisome and could result in individuals injecting substances of unknown origin.

Several experts said the popularity for the experimental drug could be connected to the increasing price of licensed slimming treatments such as Mounjaro.

Legal Position and Implementation

Marketing retatrutide on TikTok or messaging apps is illegal in the UK, as it is an unlicensed drug that cannot be marketed or distributed for personal consumption under the British medical regulations.

Some influencers attempt to circumvent the regulations by referring to the drug as a “research chemical” or citing it as “not for human consumption”. The substance is not a restricted substance, but promotion and distribution can still violate medicines, advertising, and consumer laws, potentially leading to penalties, prosecution or prison.

Platform Response and Content Elimination

Based on TikTok, the platform has taken down problematic content and banned related hashtags and search suggestions. The company stated it was committed to maintaining the service safe and investing in strengthening enforcement strategies.

Digital Trading Operations

Investigations also found groups with up to 9,000 participants selling retatrutide using Telegram's integrated discovery tool, which operates like a public directory. Typing “retatrutide” instantly displays channels with thousands of users, filled with images of weight loss, glowing testimonials and step-by-step guides for mixing or administering at home.

Within moments of joining one community, a seller posted WhatsApp details, where most transactions take place. The seller sent an instruction manual and promised delivery within two days. When asked whether the substance was authentic, one seller said: “You can’t be sure.” Another shared a image of a alleged laboratory certificate. None asked about weight, medical conditions or past usage.

Item Details and Costs

Inside these communities, messages show black plastic packages with postal service labels, stating to include new batches. One communication stated: “It took eight of us to load them this morning.”

Buyers can choose between powder vials, prepared at home with purified liquid, or pre-filled pens typically priced at 160 pounds for 20 milligrams. When asked how long a injector should last, sellers give conflicting answers ranging from a several days to “depends on your body”.

Platform Moderation and Safety Actions

A spokesperson for Telegram stated it regularly moderated harmful 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”.

Healthcare Professional Warnings

“Individuals are injecting substances they cannot confirm. Even if the research behind retatrutide is sound, these digital versions may not contain what they advertise,” said Jason Murphy, the head of pharmacy at Chemist4U.

A medical professional of an online medical service linked the surge in interest to recent price rises for approved slimming drugs such as Mounjaro. “With prices increasing, patients are using online platforms. But fake injections are extremely risky. You can’t be certain what’s contained or whether the conditions they were produced in was clean,” she explained.

Her staff has already encountered patients harmed by personal administration from unconfirmed suppliers. “We understand the disappointment, but purchasing from Telegram or communication platforms is taking chances with your well-being,” said the doctor. “These materials could be contaminated or incorrectly dosed.”

Producer Position

A representative from the pharmaceutical company stated the substance was in phase 3 research studies and had not been evaluated or authorized by any regulatory agency globally. “Therefore at this point no one can market [it] for human use,” they explained, adding that any product “falsely representing itself as a Lilly experimental product not yet approved … may subject patients to potentially significant health risks”.
