As has been stated, all Anabolic Androgenic Steroids (AAS) can increase the hematocrit, or percentage of the blood that is red blood cells (RBC's). EQ has a reputation for doing this as well; not sure if any studies show it's any worse than the others.
At any rate, the problem is one of viscosity, or thickness of the blood. More hemoglobin is good, meaning more oxygen delivery to the tissues, UP TO A POINT. After that optimal point is reached, there are diminishing returns.
Why? Because blood flow is inversely proportional to blood viscosity. And if flow decreases, so does O2 delivery to the tissues, no matter HOW much hemoglobin is on board.
Usually, around 45 is an optimal male hematocrit, but this will vary somewhat based on other variables.
If the hematocrit is too high, blood donation is a simple way to remedy the problem.
Inflammation in the blood stream, due to multiple problems, may also influence viscosity; RBC's may stack up like plates (rouleaux formation). Dehydration is another common cause of increased viscosity.
Another good reason to have labs checked regularly.
Forewarned is forearmed, bros!!
As to doses, it will vary individually. 300 might really increase one guys RBC's, and 600 not so much for another. LABS!
