A shadow market for unlicensed slimming drugs is propelled by TikTok fitness influencers and vendors on messaging platforms, based on recent findings.
Retatrutide, which remains in research studies, is being advertised by online personalities for its alleged fat-burning properties. Followers are encouraged to message these profiles privately for supplier links, while also receiving promotional offers.
Separately, a robust market exists on Telegram, where groups with thousands of participants share “before and after” photos, injection guides and claims of rapid British shipping. Vendors market the drug there before directing customers to other platforms for transactions.
Retatrutide is an experimental injection developed by US drugmaker Eli Lilly. The treatment targets three gut hormones – GLP-1, glucose-dependent insulinotropic polypeptide and pancreatic hormone. Early trials suggest it could assist patients lose 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.
Nevertheless, physicians and chemists have cautions that the distribution of what is still an unlicensed medication in the United Kingdom is worrisome and could result in users administering substances of unknown origin.
Several professionals said the popularity for the experimental drug could be connected to the rising cost of approved weight loss products such as Mounjaro.
Selling the unapproved drug on social media or messaging apps is prohibited in the UK, as it is an unapproved medication that must not be marketed or supplied for human use under the Human Medicines Regulations 2012.
Several content creators attempt to sidestep the regulations by referring to the substance as a “research chemical” or describing it as “not for human consumption”. The substance is not a restricted substance, but promotion and distribution can still breach pharmaceutical, advertising, and customer laws, risking penalties, legal action or prison.
According to TikTok, the platform has taken down problematic content and banned associated keywords and query recommendations. The organization stated it was dedicated to maintaining the service secure and allocating resources in enhancing enforcement strategies.
Research also discovered communities with up to nine thousand participants selling retatrutide using Telegram's integrated search feature, which functions like a public directory. Typing “retatrutide” instantly displays channels with thousands of members, filled with images of weight loss, positive reviews and detailed instructions for preparing or administering at home.
Within moments of entering one group, a seller shared contact information, where most transactions occur. The vendor sent an instruction manual and guaranteed delivery within two days. When questioned whether the product was genuine, one seller said: “You can’t be sure.” Another provided a photo of a alleged testing documentation. None inquired about body mass, health issues or previous experience.
Within these groups, messages show dark colored parcels with postal service stickers, stating to contain new batches. One communication 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 sold at 160 pounds for 20mg. When questioned how much time a pen should be used, sellers give contradictory responses ranging from a few weeks to “depends on your body”.
A spokesperson for Telegram said it regularly monitored dangerous content 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”.
“Individuals are administering substances they cannot confirm. Even if the science behind this drug is sound, these digital versions may not include what they advertise,” stated Jason Murphy, the head of pharmaceutical services at a pharmacy service.
A medical professional of an online medical service connected the surge in interest to recent price rises for approved slimming medications such as Mounjaro. “With costs rising, individuals are turning to online platforms. But counterfeit injections are extremely dangerous. You can’t be certain what’s contained or whether the environment they were made in was clean,” she explained.
Her team has already encountered patients harmed by self-injection from unverified sources. “We understand the frustration, but purchasing from messaging apps or communication platforms is taking chances with your well-being,” stated Wyllie. “These substances could be contaminated or improperly measured.”
A representative from Eli Lilly said the substance was in third stage research studies and had not been evaluated or authorized by any government authority globally. “Consequently at this point no one can market [it] for personal consumption,” they explained, noting that any product “falsely representing itself as a company investigational product not yet authorized … may subject users to potentially serious health risks”.
