Here the long story: I inject 40MG every 4 Days: Been about 10 months since my last blood donation. I was without insurance for a while so didn't get my levels checked, and they have really been pretty much in line the last couple years so I put it off. Now that I have insurance again, I had a physical and just got the results today: Total T- 1050 2 days post injection (so right in the middle since I inject every 4 days) Hematocrit- 55 Hemoglobin 18.1 My urologist hasn't seen these numbers yet, got it from the nurse. I went right to the blood bank near my job to drop a pint today. They did the finger prick and denied me. Said my hemoglobin was 18.7 and the max they will take is 18.5. Shit! I called the good ol Red Cross and they told me the max limit for hemoglobin they use is 20 - made an appt for tomorrow. Hopefully its under 20 when I go tomorrow. These portable finger prick machines don't seem to be 100% accurate. I think I will lower my dose to 40mg every 5 days or 30mg every 4 days. Thats IF the doc doesn't make me come off T until the Hct lowers. I'm speaking with him tomorrow.
