Saturday, 12 December 2020 Sebastiana Lopez, a Para-javelin thrower from the United States, has been handed a four-year ban by the International Paralympic Committee for an anti-doping violation. The F54 thrower returned a positive test from a urine sample provided on August 26 2019 during the Lima 2019 Parapan American Games in Peru. The substance, GW501516, is on the World Anti-Doping Agency's Prohibited List under the class of hormone and metabolic modulators. This means she will be stripped of two of her medals from the 2019 Parapan American Games - a silver in the F54 women's javelin throw and a bronze in the women's shot put F53/54/55.
