Paraguayan weight‑loss 'pen' smuggling halts in Brazil amid health warnings

Brazilian authorities seized large shipments of unapproved weight‑loss injections and oral pens originating in Paraguay. On 11 July, the Federal Highway Police intercepted a car in Pindamonhangaba (SP) carrying 1,775 ampoules of TG, 52 of retatrudita, 33 of injectable GHK‑Cu and other products hidden in the fuel tank. A separate operation on 10 July at the Foz do Iguaçu customs checkpoint captured 5,850 weight‑loss pens containing tirzepatida (Mounjaro) and retatrudita, stored without refrigeration in a van with Paraguayan plates. On 14 July, customs agents seized a Paraguayan truck at the International Bridge of Friendship loaded with additional pens, agricultural pesticides and other contraband, valuing the cargo at roughly R$ 500 000.

Health experts warn that rapid weight loss driven by these unregulated drugs can cause severe muscle loss (sarcopenia), increasing cardiovascular risk, and may lead to secondary issues such as genital tissue flaccidity in women. Cardiologist Omar Britto stresses that losing lean mass “undermines metabolic function and protects the heart,” while gynecologist Bruna Paschoalim notes that dramatic fat reduction can reduce tissue support in the intimate area, producing discomfort and aesthetic concerns. Pharmaceutical company Eli Lilly highlighted that tirzepatida requires strict temperature control; without it, product efficacy and safety cannot be guaranteed.

The seizures illustrate a growing illegal market fueled by price gaps between Brazil and Paraguay, where the same medications can cost roughly ten times less. Authorities emphasize that importing such products bypasses Brazil’s sanitary regulations, posing public‑health hazards and prompting stricter enforcement at border crossings.
