Doc wants me to donate blood before my next shot of Nebido. Before my first shot, I had a RBC count of 50.5% (Ref 43-53%). With my first shot already in my blood, I suspect my RBC count went up. I am in a high altitude location which increases your RBC by 15-30%, making TRT treatment more challenging. Question – is it time to donate with these numbers and how oftern should I do it? Doctor says I shold donate right before each shot (8-10 weeks).
