Illegal Weight-Loss Drugs Sold in UK Under Cover of Strong Trustpilot Ratings, Regulators Warn
Unlicensed injectables like retatrutide and tirzepatide are being marketed online by firms with high review scores despite seizure-and-ban efforts
Investigators have uncovered a surge in the online sale of unlicensed weight-loss drugs in the UK, sold by firms that maintain high customer ratings on consumer-review platforms — a practice that regulators say poses a major public-health risk.
Despite warnings from authorities, dozens of businesses have marketed experimental or prescription-only treatments such as retatrutide and tirzepatide under the guise of legitimacy, relying on glowing reviews to lure buyers.
A recent enforcement operation dismantled what is believed to be the first illicit manufacturing facility in Britain producing counterfeit weight-loss injections.
Authorities seized over 2,000 completed pens and tens of thousands of empty syringes and raw chemical ingredients — a haul representing the largest-ever interception of trafficked weight-loss medicines globally.
The seized drugs were labelled as containing ingredients from established pharmaceuticals, though regulators emphasised they were unapproved, potentially dangerous, and entirely unauthorised for sale.
The illicit drugs were being marketed by firms that boasted high Trustpilot scores: one active site promoting unlicensed retatrutide injections had a 4.7 out of 5 rating even while regulators issued a site-closure notice.
Others maintained 4.4 or 4.6 ratings, bolstered by favourable customer reviews claiming rapid weight loss and discreet delivery.
Experts say these ratings act as a false stamp of legitimacy and mislead consumers into believing the products are safe and lawful.
Regulators, including the national medicines authority and advertising watchdog, have stepped up enforcement.
They warn that these unregulated compounds may be contaminated, inaccurately dosed, or poorly sterilised, putting users at risk of severe side effects such as infections, blood-sugar irregularities, pancreatitis, or cardiovascular problems.
Prescription-only medicines of this type must only be supplied by licensed pharmacies following medical assessment and prescription — a rule frequently ignored by online sellers.
While legitimate weight-loss drugs exist under strict medical supervision, officials urge the public to obtain any medication only via licensed pharmacies, following a prescription and with proper medical guidance.
They warn that buying from unregulated sources not only jeopardises individual health but fuels a black market driven by profit rather than patient wellbeing.
As demand for weight-loss treatments rises, authorities face growing pressure to close regulatory loopholes, crack down on illegal sellers, and safeguard patients from dangerous and unlicensed products.
