My red blood count is high too- has been for years. Test is the major reason. I also have sleep apnea which is likely due to the test. Both contribute to higher RBC levels. My doctor prescribes 200mg Test/week. ( I double it on my own). He will also prescribe Deca if I can get my RBC count down. He says I must give a pint of blood a week to get the level down. I gave 2 pints last month aand it didn't work. Have to stick to the 1 pint a week to get the RBC down and get the Deca.
