Sort of an interesting anecdote about hematocrit levels-
About 10 years ago (late 20s) I had a duration of blood tests over a period of about 8 months and HC was one of the things on the test, probably 7 blood tests. My HC levels fluctuated wildly, I was cycling at the time, but didn't really have a structured plan. My levels would be anywhere from 41 to 50 seemingly without reason, they'd go up, then down, then up, then up, then down, etc.
It made me think about the blood passport and how it might be sort of useless, because I wasn't doing any PEDs and my HC varied a ton.
