Jul 25, 2017 Pretty sure I have found the reason my levels are so high. I have been supplementing with natural supplements that contribute to raising blood levels. I'm stopping this and will see what just test and basic supplements do. I have been taking blood builders for a long time, since I'm no longer natural I don't think I need help "building blood" That is what the test will do, I have for a long time been taking extra supplements which help increase blood...... I'm going to get some more blood work, this time full blood panels and will see how my RBC levels rebuild The supplements I have been taking for a long time help with increasing your blood and I don't microdose these supplements. I take a high dose of them with every meal. I've stopped using them since and will monitor my red blood cell counts. I'm positive it is the supplements that are increasing my RBC much higher than just taking testosterone . I think this might sound kind of stupid but I have always taken these supplements and didn't stop when jumping on gear!
