Re: How does EPO work, and how is it bad for you?

Hi Eric,
 EPO is generally well tolerated, side effects can include chest pain, 
swelling due to fluid retention, tachicardia(rapid heart rate) and head 
pain, shortness of breath/skin rash, joint pain, diarrhea and sometimes 
flu like symptoms.
Use of aspirin prior to use can minimise side effects. It is possible, as 
the blood can become dangerously thick, to use intavenous saline solution 
and diruretics to fool blood tests.
