What is boldenone?
Boldenone is a steroid that enhances muscle mass and strength. It is used in animal feed production.
However, several Colombian athletes have been affected by this substance, which is highly prevalent in beef, given that it is administered to cattle to improve the final product.
Several athletes in the country have been affected by the substance after consuming beef. Some notable cases include weightlifters Yenny Sinisterra, Juan Solís, and Ana Iris Segura, cyclist Fabián Puerta, and tennis player Robert Farah, among others.
