If you planing to take anabolics or you are on , have a blood test for Factor 5 Blood Disorder (Leiden).
Factor 5 is an inherited disorder of blood clotting is the most common inherited form of thrombophilia. Between 3 to 8 percent of Caucasian(white) population in the USA carry one copy of the Factor 5 mutation in each cell, and about 1 in 5000 people have two copies of the mutation. Anabolics increases red blood cells and if you have the disorder the risk of getting blood cloths is very high. I know a few bb died from not knowing that they had the disorder.
I am posting this so before you try anything consult a physician.
