Your ferritin levels are low and may or may not be a problem. Testosterone increases hemoglobin and hematocrit which uses up iron, ferritin is iron storage. Iron deficiency without anemia would see normal but bottomed out hemoglobin and low MCH, MCV, MCHC and high RDW.
If you were to raise the ferritin, hemoglobin and hematocrit are likely to increase. At what ferritin level that occurs to a meaningful degree is unknown.
I'm awaiting your vitamin D level, which can affect ferritin levels. Vitamin C also greatly affects ferritin, more so than vitamin D alone.
If your vitamin D levels are fine, the low ferritin, as a result of the TRT could be your bodies way of balancing the hemoglobin and hematocrit.
How do you feel?
