i recently got my hematocrit tested and it was only 40% and my hemaglobin was 14.5%. the test was even taken after a couple days rest. is there any ways other than EPO, iron supplements, and altitude tents to raise both of these numbers. my doctor said it was borderline low so he wouldn't prescribe anything to me. I want to get it in the 50s, how hard is it to raise it that much??
