Illegal weight-loss jabs being sold on TikTok ‘not approved for humans’; UK Regulators issue urgent warning

UK health authorities are sounding the alarm: illegal weight-loss jabs are being advertised and sold via TikTok and other social media platforms, injections that are not approved for human use. These posts often promote so-called “miracle” pens or injectables like “Triple G” or Retatrutide, with little or no medical oversight.Regulators, including the Medicines and Healthcare products Regulatory Agency (MHRA), and watchdogs have issued urgent warnings. According to them, these unlicensed weight-loss injections may contain unsafe substances, wrong doses, or even contaminants, and may lead to serious side effects.Retatrutide, an investigational drug still undergoing clinical trials, targets three hormone receptors – GLP-1, GIP, and glucagon – to help control appetite and weight. It is not yet approved by regulators for human use.Now, sellers on TikTok, Instagram, and other platforms have been marketing Retatrutide as a cheap alternative to expensive, approved fat-jabs like Mounjaro. Some listings explicitly offer unapproved versions, or claim to have the product for sale “outside trials.” These are often outside the oversight of regulators. The MHRA in the UK has publicly declared that any products being offered for sale that claim to contain Retatrutide outside of official clinical trials are likely illegal. They warn that they may contain unknown or harmful substances, incorrect doses, may not meet safety standards, and are not approved for human use. Eli Lilly (the maker) has made similar statements.Furthermore, social media posts have been removed as well when exposed, but new ones keep appearing.The regulators emphasize that legitimate weight-loss drugs (such as semaglutide, liraglutide, tirzepatide) must be prescribed by qualified medical professionals. Anything purchased outside legal supply chains may be fake, unsafe, or improperly dosed. The Advertising Standards Authority (ASA) is also acting, penalizing firms or social media posts that promote prescription-only weight loss jabs without appropriate medical supervision. Advertising prescription medicines without a prescription is illegal in the UK.Unknown or counterfeit contents: Fake pens or injectables may not contain the drug they claim to have. They might contain wrong ingredients, dangerous contaminants, substituted substances, or improper mixture/dose. For example, MHRA investigations uncovered fake Ozempic or Saxenda pens, some containing insulin instead of the promised active drug.Incorrect dosage and lack of quality control: Without regulated formulation or oversight, doses can vary wildly. Some illegal versions may deliver too much (risking severe reactions), or too little (making them ineffective). In some cases, people have been hospitalised because of unregulated injections.Severe side effects and fatalities: As per last year’s report, at least 18 deaths in the UK have been reported to the MHRA over the past few years, suspected to be connected to weight-loss injections used outside supervision. Common side effects seen include nausea, vomiting, diarrhoea, and gastrointestinal discomfort. More serious complications: pancreatitis (inflammation of the pancreas), gallbladder disorders, and potential long-term digestive issues. Some people have had to undergo gallbladder removal.Medical conditions and compromised safety: People buying online or through social media lack medical supervision: no proper check of body mass index (BMI), medical history, or contraindications such as pregnancy, kidney/liver disease, or history of digestive issues. That increases risk.Removal of illicit posts: Social media platforms are being asked to take down accounts or listings offering these unapproved injections. Investigations (e.g., by The Independent) have led to takedowns. Regulation of advertising: The Advertising Standards Authority (ASA) is enforcing rules to stop prescription-only drugs from being promoted on social media or via unverified ads. Tighter controls on online pharmacies: New guidance requires stricter verification of patient information (weight, height, BMI) and forbids prescribing weight-loss injectables via questionnaire-only methods. Some pharmacies have been disciplined. Amidst the surge of such illegal drug sales, here are some tips on how you should protect yourself and stay safe:First things first: Don’t buy weight-loss jabs from social media, TikTok accounts, or websites that don’t require a prescription or medical consultation. Furthermore, always check with a qualified healthcare provider before using any weight-loss drug. If purchasing legally, ensure the medication is prescribed and the product is from a licensed pharmacy. Additionally, watch for warning signs: extremely low prices, no medical oversight, lack of info on side effects or dosing. Finally, report suspicious posts or medicines to MHRA (via the Yellow Card scheme) or other relevant regulators.
