just wanted to add one more thing...im considered secondary •Polycythemia resulting directly to the use of testosterone, i dont have a disease and the doc has argued with the blood connection for dumping perfectly good blood but they dont listen,,im just glad they will do it for free..there loss and to the people who could have benefited from my blood donation...lots of iron and red blood cells wasted..hope this helps somebody understand ....also on another note...when i first was told that i must start giving to lower my hemo i almost freaked out! thought it was end of the world,i had to give 6 weeks in a row every wensday!! remember drink lots of water and eat plenty and youl be fine,i also add a zanax and drink a few first,they always have a fan on me and lay me back so that blood cant leave my brain cause legs are higher than your head,otherwise i might pass out...
