An underground market for unlicensed slimming medications is being driven by social media fitness personalities and sellers on communication apps, according to new investigations.

Investigational Drug Gaining Popularity Via Social Media

Retatrutide, which remains in clinical trials, is being promoted by online personalities for its supposed weight-reducing effects. Viewers are urged to contact these profiles privately for source information, while also receiving discount codes.

Thriving Trade on Social Networks

Separately, a robust market exists on messaging services, where communities with thousands of members share “before and after” photos, injection guides and claims of rapid UK delivery. Sellers market the substance there before redirecting buyers to WhatsApp for transactions.

Understanding Retatrutide

Retatrutide is an investigational injection developed by American pharmaceutical company Eli Lilly. The treatment targets three intestinal hormones – GLP-1, glucose-dependent insulinotropic polypeptide and glucagon. Preliminary studies suggest it could help patients reduce up to a quarter of their total weight. Referred to as the “triple G”, the drug is being hailed digitally as the successor to Ozempic.

Medical Professionals Express Concerns

However, physicians and pharmacists have warned that the sale of what remains an unlicensed medication in the UK is worrisome and could lead to individuals administering substances of unknown origin.

Several professionals said the popularity for retatrutide could be linked to the increasing cost of licensed slimming treatments such as Mounjaro.

Regulatory Position and Implementation

Selling the unapproved drug on TikTok or Telegram is illegal in the UK, as it is an unapproved drug that cannot be marketed or supplied for human use under the Human Medicines Regulations 2012.

Several content creators attempt to sidestep the rules by referring to the drug as a “research chemical” or citing it as “not for human consumption”. Retatrutide is not a controlled drug, but advertising and distribution can still violate pharmaceutical, marketing, and customer laws, risking fines, prosecution or prison.

Platform Response and Material Removal

According to the social media company, the platform has taken down problematic material and prohibited related keywords and query recommendations. The organization stated it was committed to maintaining the platform secure and allocating resources in strengthening enforcement strategies.

Digital Marketplace Operations

Investigations also found communities with up to 9,000 members marketing retatrutide using the platform's integrated discovery tool, which functions like a public directory. Entering “retatrutide” immediately brings up groups with thousands of users, populated with photos of weight loss, glowing testimonials and step-by-step instructions for preparing or injecting at home.

After moments of joining one group, a vendor shared WhatsApp details, where the majority of purchases take place. The vendor sent an guidebook and guaranteed delivery within 48 hours. When questioned whether the substance was genuine, one seller responded: “You can’t be sure.” Another provided a photo of a alleged testing documentation. Not one asked about weight, health issues or past usage.

Product Information and Costs

Within these groups, messages display black plastic parcels with Royal Mail stickers, claiming to contain new batches. One message read: “It took eight of us to load them this morning.”

Buyers can select between powder vials, mixed at residence with sterile water, or pre-filled injectors typically priced at £160 for 20mg. When questioned how long a injector should last, sellers give conflicting responses ranging from a few weeks to “depends on your body”.

Service Moderation and Safety Actions

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

Healthcare Professional Cautions

“Individuals are injecting materials they can’t verify. Even if the research behind this drug is valid, these digital versions may not contain what they claim,” stated a pharmacy expert, the director of pharmaceutical services at Chemist4U.

A medical professional of an online medical service linked the surge in interest to recent price rises for approved slimming medications such as Mounjaro. “With prices rising, patients are using online platforms. But fake injections are extremely dangerous. You cannot know what’s contained or whether the environment they were produced in was clean,” she explained.

Her staff has already seen patients harmed by personal administration from unconfirmed suppliers. “We understand the frustration, but buying from messaging apps or WhatsApp is taking chances with your well-being,” stated the doctor. “These materials could be impure or improperly measured.”

Manufacturer Statement

A representative from the pharmaceutical company stated the substance was in phase 3 clinical trials and had not been evaluated or authorized by any government authority anywhere in the world. “Consequently at this time no one can sell [it] for human use,” they said, noting that any product “misleadingly claiming itself as a Lilly experimental substance not yet approved … may subject patients to possibly serious medical dangers”.
