My RBC and hemoglobin are high on my TRT labs—is this dangerous?
I just got my first set of labs back after three months on T, and my hemoglobin and hematocrit are flagged as high. Should I be worried about this, or is it just part of the process?
A high red blood cell (RBC) count or hemoglobin level, known as erythrocytosis, is a common side effect of TRT because testosterone stimulates the production of erythropoietin in the kidneys. While this can improve oxygen delivery, excessively thick blood may increase the risk of hypertension or cardiovascular strain if not managed properly. At HeydayMD, our clinicians closely monitor these markers and may recommend dosage adjustments or therapeutic phlebotomy to keep your levels in a safe range. Working with a specialized clinic ensures that your protocol is optimized for both performance and long-term heart health.
Every body is different. A licensed provider can look at your own labs and symptoms.
