Recent revelations highlight the alarming trend of individuals purchasing weight loss injections from unregulated sources on social media, raising serious concerns about the potential health risks involved. Experts warn that such actions can lead to severe and life-threatening side effects.
Unregulated Purchases and Personal Accounts
The experiences of Keeley, a 39-year-old mother from South London, serve as a cautionary tale. After giving birth, Keeley sought to shed a stone but opted for a cheaper alternative to the prescription drug Mounjaro. Spotting an advertisement on Facebook for “skinny jabs” priced at £35 per week, she reached out to a seller, who turned out to be a beauty therapist.
Reflecting on her decision, Keeley stated, “It was such a stupid thing to do. It was just sent in the post inside an insulin needle. I had no idea where it actually came from. I could have died.” The delivery arrived in a non-branded package, accompanied by minimal instructions, which raised immediate red flags regarding its legitimacy.
Keeley’s initial excitement quickly turned to concern as she experienced adverse effects after just a week of use. “I had headaches and stomach aches, and after the second week, I wasn’t even sure if there was anything in the syringe,” she recounted, highlighting the uncertainty surrounding the content and safety of the drug.
The Risks of Counterfeit Medications
Another individual, Jimmy Stone, a 34-year-old property manager from Windsor, shared his experience with weight loss jabs obtained through TikTok. He began using what he believed to be Retatrutide, a drug still undergoing clinical trials, after being approached by a company for brand ambassadorship. “It burnt the fat around my stomach, but I did get really bad heartburn,” he explained.

Despite his initial weight loss, Stone’s use of the unregulated drug, which he noted was packaged under a different name, raised suspicions about its authenticity. “You don’t know what’s in it; they could be filling it with anything. I just think it’s a bit of a scam,” he added, underscoring the precarious nature of sourcing medications from dubious platforms.
Expert Opinions on the Dangers
Dr. Kasim Usmani, a private GP based in Surrey, cautioned against the dangers of acquiring weight loss drugs from unverified sellers. “We are seeing some promising outcomes with clinical trials of Retatrutide, but it needs to be further investigated for clinical safety for human use,” he remarked. The potential for severe side effects, including increased risk of cancer and gastrointestinal disorders, remains unknown due to the drug’s untested nature outside of clinical settings.
He emphasised that medications sourced from unregulated suppliers not only lack proper storage and handling but may also be dispensed by individuals without professional training. “Only buy weight loss drugs through legitimate sources, such as a pharmacy or GP that are regulated,” Dr. Usmani advised, stressing the importance of ensuring the product’s packaging is professional and that the formulation appears clear.
Regulatory Responses and Consumer Awareness
The Medicines and Healthcare products Regulatory Agency (MHRA) has reiterated that weight loss drugs, including Retatrutide, are prescription-only and should only be procured through qualified healthcare professionals. They warned that any products marketed as containing Retatrutide outside of authorised clinical trials are likely illegal and pose serious health risks.

Eli Lilly, the pharmaceutical company behind these drugs, stated, “No one can legally sell it for human use. Counterfeit and black market medicines are untested, unregulated, and potentially dangerous—sometimes deadly.”
Social media platforms, including Meta, have taken steps to remove content that promotes the sale or distribution of such products, yet the prevalence of these advertisements remains a significant concern.
Why it Matters
The increasing trend of purchasing weight loss medications from unregulated sources on social media not only endangers individual health but also underscores a broader public health issue. As more people seek quick fixes for weight management, the temptation to bypass legitimate medical avenues poses risks not just to personal well-being but also to the integrity of healthcare systems. Educating the public on safe practices and the potential dangers of counterfeit medications is crucial in mitigating these risks and ensuring that individuals make informed choices about their health.
