Not to mention a pulmonary embolism. People def need to be donating blood. I tell you the first time you see a blood transfusion save someone's life you become an instant believer in donating.

Androgens also increase the H&H because testosterone is a potent red bone marrow agonist, so weather more EPO is produced or not RBC count goes up with test.
