A shadow market for unlicensed weight-loss drugs is propelled by social media fitness personalities and sellers on communication apps, according to recent findings.
The experimental drug, which is still in research studies, is being advertised by social media influencers for its alleged fat-burning effects. Viewers are encouraged to message these profiles directly for supplier links, while also receiving promotional offers.
Separately, a flourishing trade exists on messaging services, where groups with thousands of members share comparison images, injection guides and claims of rapid British shipping. Sellers promote the substance there before directing customers to other platforms for transactions.
Retatrutide is an experimental injection created by US drugmaker Eli Lilly. The drug affects three gut hormones – glucagon-like peptide-1, GIP and glucagon. Early trials suggest it could help individuals reduce up to 25% of their total weight. Referred to as the “triple G”, the substance is being hailed online as the next Ozempic.
However, doctors and chemists have cautions that the sale of what is still an unapproved medication in the UK is a cause for concern and could lead to users administering products of uncertain source.
Several professionals stated the demand for retatrutide could be linked to the increasing price of licensed slimming products such as Mounjaro.
Marketing the unapproved drug on social media or messaging apps is illegal in the United Kingdom, as it is an unapproved drug that must not be promoted or supplied for human use under the British medical regulations.
Some content creators attempt to circumvent the rules by calling to the substance as a “research chemical” or citing it as “not for human consumption”. The substance is not a restricted substance, but advertising and supply can still breach pharmaceutical, advertising, and consumer regulations, potentially leading to penalties, legal action or prison.
Based on TikTok, the platform has taken down problematic material and banned related hashtags and search suggestions. The organization stated it was committed to maintaining the platform secure and allocating resources in strengthening compliance measures.
Research also discovered groups with up to 9,000 members marketing retatrutide using the platform's built-in search feature, which operates like a public directory. Typing “retatrutide” immediately brings up groups with thousands of members, filled with photos of weight loss, glowing testimonials and detailed guides for preparing or administering at residence.
Within minutes of entering one group, a vendor posted contact information, where the majority of transactions occur. The vendor sent an guidebook and promised delivery within 48 hours. When questioned whether the substance was authentic, one seller responded: “You can’t be sure.” Another shared a image of a alleged testing documentation. None asked about body mass, health issues or past usage.
Within these groups, posts show dark colored parcels with Royal Mail stickers, claiming to contain new batches. One message stated: “It took eight of us to load them this morning.”
Buyers can choose between dry substance containers, prepared at home with purified liquid, or pre-filled injectors usually priced at £160 for 20 milligrams. When asked how much time a pen should be used, sellers give conflicting responses varying between a few weeks to “depends on your body”.
A representative for the messaging service stated it regularly moderated dangerous material on its platform including material that encouraged the “misuse of controlled medications”. The company noted that it eliminated “millions of pieces of harmful content each day”.
“Individuals are administering substances they cannot confirm. Although the research behind this drug is sound, these online products may not include what they advertise,” said a pharmacy expert, the head of pharmacy at a pharmacy service.
A medical professional of an online medical service linked the increase in demand to recent price rises for authorized slimming drugs such as Mounjaro. “With prices increasing, individuals are turning to online platforms. But fake injections are extremely risky. You cannot know what’s inside or whether the conditions they were produced in was sterile,” she explained.
Her team has already encountered individuals injured by self-injection from unverified sources. “We understand the disappointment, but buying from messaging apps or WhatsApp is taking chances with your health,” stated Wyllie. “These materials could be impure or improperly measured.”
A representative from Eli Lilly said retatrutide was in phase 3 research studies and had not been evaluated or authorized by any government authority globally. “Consequently at this point no one can sell [it] for human use,” they explained, noting that any item “misleadingly claiming itself as a Lilly investigational substance not yet approved … may subject users to possibly serious health risks”.
