Brazilian tax authorities report 20-fold increase in illicit weight-loss pen seizures

Brazilian tax authorities seized over R$ 80 million in weight-loss pens during the first half of 2026, representing a significant escalation in illicit trade compared to the same period in 2025. The surge suggests a rapid expansion of the black market for GLP-1 receptor agonists, though the specific origin of the counterfeit or smuggled goods remains unconfirmed.
