The last time the supplement EPO (erythropoietin) made headlines was in 2013.
That’s when cyclist Lance Armstrong admitted he cheated by using the performance-enhancing hormone to win all seven of his Tour de France titles.
Now, EPO is in the news again. Researchers say early findings show that it may have the potential to become a treatment for COVID-19.
What’s more, since it is completely natural, it has fewer side effects than many of the drugs now being tested against coronavirus.
