No way, this is a pipe dream. Stop fooling yourself. Nothing affects HCT more than testosterone.
Also, donating blood with the intent of controlling hematocrit, long-term doesn’t work. Your hemoglobin and hematocrit reach previous levels prior to donation within 2-3 weeks and all you’re doing is losing iron and potentially crashing your ferritin levels.
My doctor doesn’t care about hematocrit, he focuses more on the hemoglobin.
