Something that is often dismissed is also one of the most important things to observe during and after cycles: blood counts. Really this is far more important than your precious testosterone levels. I'll even go as far as saying that it's more important than estrogen levels. Gynecomastia won't kill you. Ignoring blood level "forever" can certainly be fatal. In order to understand the effects of steroids, it's entirely important to understand the process in which blood is affected. The amount of RBC's that you have matters. Too little, you're in trouble. This is called Anemia. Too many RBC's you're still in trouble, and that's called Polycythemia. Hepcidin Suppression and Oxygen Deprivation are "2" major area's where steroids affect your blood.
Best thing is a quick blood test called Complete Blood Count (CBC) panel . Were looking for Hematocrit , (HCT). Hematocrit is a measure of how thick your blood is. The more RBC's you have, the higher the number will be. "Your blood just got super thick and super slow.
You can use "Lab Reference ranges. The goal is to stay with in the range. If your HCT level goes a little over a bit, it's not the end of the world, but don't ignore it. If it get's to around 58%,you have some serous issues to attend to. And I'll be the first to say, It can get up there pretty fast...
