An underground economy for unlicensed weight-loss drugs is being driven by social media fitness personalities and sellers on messaging platforms, according to recent findings.

Investigational Treatment Acquiring Popularity Via Social Media

Retatrutide, which is still in research studies, is being advertised by social media influencers for its alleged weight-reducing effects. Viewers are urged to message these accounts directly for source information, while also receiving promotional offers.

Active Trade on Messaging Platforms

Additionally, a flourishing trade exists on messaging services, where communities with thousands of participants share “before and after” images, administration instructions and claims of next-day British shipping. Vendors promote the substance there before directing customers to other platforms for transactions.

Learning About The Experimental Drug

Retatrutide is an experimental injectable created by American pharmaceutical company Eli Lilly. The drug targets three intestinal hormones – GLP-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Early trials suggest it could help individuals reduce up to a quarter of their body weight. Referred to as the “triple G”, the substance is being hailed online as the successor to Ozempic.

Medical Professionals Voice Worries

However, doctors and pharmacists have warned that the sale of what is still an unlicensed drug in the UK is a cause for concern and could result in users injecting substances of unknown origin.

Several experts stated the demand for retatrutide could be connected to the rising price of licensed weight loss treatments such as Mounjaro.

Legal Position and Implementation

Marketing the unapproved drug on social media or Telegram is illegal in the United Kingdom, as it is an unlicensed medication that must not be promoted or supplied for personal consumption under the Human Medicines Regulations 2012.

Some influencers try to circumvent the rules by referring to the substance as a “research chemical” or describing it as “not for human consumption”. Retatrutide is not a controlled substance, but promotion and distribution can still violate medicines, marketing, and customer laws, potentially leading to fines, prosecution or imprisonment.

Service Response and Content Elimination

Based on TikTok, the platform has taken down problematic content and prohibited related keywords and query recommendations. The company stated it was committed to maintaining the platform safe and investing in enhancing compliance measures.

Online Marketplace Activities

Research also found communities with up to 9,000 participants selling retatrutide using Telegram's integrated search feature, which operates like a online catalog. Entering “retatrutide” instantly displays groups with thousands of members, populated with images of weight loss, positive reviews and step-by-step guides for preparing or injecting at residence.

After minutes of entering one community, a vendor posted contact information, where the majority of purchases occur. The vendor provided an instruction manual and guaranteed shipping within 48 hours. When asked whether the substance was authentic, one seller responded: “You can’t be sure.” Another provided a photo of a alleged laboratory certificate. Not one inquired about body mass, medical conditions or previous experience.

Product Information and Pricing

Within these communities, messages show black plastic packages with Royal Mail stickers, claiming to include fresh supplies. One message read: “It took eight of us to load them this morning.”

Buyers can select between powder vials, mixed at home with sterile water, or ready-to-use pens usually priced at 160 pounds for 20 milligrams. When asked how much time a pen should last, vendors give contradictory answers varying between a few weeks to “depends on your body”.

Platform Oversight and Security Actions

A spokesperson for the messaging service stated it regularly moderated harmful content on its platform including content that encouraged the “misuse of controlled medications”. The company noted that it eliminated “millions of pieces of harmful content each day”.

Medical Expert Warnings

“People are administering materials they can’t verify. Even if the science behind this drug is sound, these digital products may not contain what they advertise,” said Jason Murphy, the director of pharmacy at Chemist4U.

Dr Crystal Wyllie of an online medical service linked the surge in interest to current price rises for approved slimming medications such as Mounjaro. “With costs rising, patients are turning to online platforms. But fake treatments are highly risky. You cannot know what’s contained or whether the environment they were produced in was clean,” she said.

Her staff has already encountered individuals injured by personal administration from unconfirmed suppliers. “We recognize the disappointment, but purchasing from Telegram or WhatsApp is gambling with your well-being,” said Wyllie. “These materials could be impure or improperly measured.”

Manufacturer Statement

A spokesperson from the pharmaceutical company said the substance was in third stage clinical trials and had not been evaluated or approved by any government authority globally. “Therefore at this time no one can market [it] for personal consumption,” they said, adding that any item “falsely representing itself as a company investigational product not yet approved … may subject users to possibly serious medical dangers”.
