I just donated a pint yesterday. I was having the classic symptoms of high RBC/HCT like hot tingly skin, shortness of breath, feeling hot, red skin, headaches. Today I feel much better. My hemoglobin/hematocrit was 17.4/51.4 prior to donating. Donating usually drops me 1 to 1 1/2 points so I should be right around 16.4/50.4. I will donate in another 3 months to keep it in check. I haven't donated in over a year so it crept up slowly on me, but now I'm set to donate regularly every 3 months so I shouldn't have a problem. Now I can start my Test/Deca cycle and not have to worry about it.....
