You know you’ve picked your friend group well when a bunch of them will sit
and theorize about the horrors of witcher biology with you when you yell
about how the fuck Geralt even stands up without passing out with a stupid
low heart rate.

and
loquaciousky https://tmblr.co/m7N5ADHFbV9XdSzadx8_yGA are delightful
people who came up with most of this.
Anyway! It’s likely that he has an enlarged heart (which I love for both
fantasy biology and narrative symbolism reasons), extremely overactive bone
marrow, and a super efficient liver. Which means the witcher trials are
basically doing an entire magical bone marrow transplant at the same time
as hugely altering two major organs! No wonder so many kids die. And
probably not all of them die during the trials, unless they take a month or
more, because in that case you run the risk of giving the candidates every
autoimmune disorder at once or aggressive leukemia, or both! And a legit
reason for only men to undergo the witcher trials - testosterone mediates
autoimmune functions, which is why more AFAB folks show signs of autoimmune
conditions than AMAB ones. If the trials upregulate immune activity as part
of supercharging the response to toxins and diseases, testosterone could be
a deciding factor in survival.
Bonus fact! With a supercharged immune system, you get things like cytokine
storms in response to anything that does get through the body’s defenses…
which Geralt shows most of the signs of when he gets that ghoul bite.
ladyalisette https://tmblr.co/mlq9we1yh1_kbuTnkLRlXkQ coming in clutch
with some more witcher biology theorizing! If witchers have supercharged
blood, they also probably have a longer latency time between “lack of
pulse” and “irreversible brain damage”, which is, idk about y'all,
excellent whump fuel, in my mind. They also might have larger reserves of
myoglobin, a muscle protein that stores oxygen like hemoglobin (sperm
whales use it as oxygen reserves while diving, apparently, and iirc human
athletes generally have more from training), which would result in very
dark/deep red muscle tissue. This would also make witchers more naturally
suited for endurance activities, because they’d have longer aerobic
respiration periods in the muscle before anaerobic respiration kicked in.
Now, if we wanted witchers to be able to do sprint activity when needed (as
they likely do), we can look at beefed up witcher livers again! Glycogen,
stored in the cells, can be quickly converted to glucose for anaerobic
respiration, but the liver regulates both glycogen storage and glycolyis
(glycogen to glucose), so it would need to be beefed up. Naturally, this
process gives you about two minutes of extra hard workload, but in a
witcher, it could be upped if the storage happened in the body cells as
well. At the cost of insane caloric needs, of course! I hear Geralt eats
whole sticks of butter in the games and this would be why. Also, Ali says
“as a result, if you were to try to eat a witcher, they’d taste weirdly
sweet and caramelize like liver.”
