If smoking cigarettes raises HCT do you guys think weed would also? My hct was 49.1 then I donated blood and it went down to 46 now about a month and a half later it is 49.5. I'm worried my HCT will keep rising while on TRT and get to high. I'm trying to figure out anything that could raise HCT so far the things on my list are dehydration, smoking, sleep apnea, any lung problems, and diet. Does any one have any ideas on how to lower HCT while on TRT or cycling? Has any one else experienced this problem I really don't want to have to give blood every month through a theraputic withdrawl and definitely don't want to drain my own blood. I don't mind giving blood every 56 days I'm just trying to figure out how to control HCT.
