Can erythropoietin be used to enhance pigeon performance?

Erythropoietin (EPO) is a hormone that stimulates red blood cell production, which can enhance oxygen delivery to muscles, potentially improving endurance and performance in athletes, including pigeons. However, the use of EPO in racing pigeons is considered unethical and is banned in competitive settings due to its classification as a performance-enhancing drug. Additionally, the misuse of EPO can lead to serious health risks. Therefore, while EPO could theoretically enhance performance, its use in pigeons is both illegal and harmful.
