Does fasting prior to blood draw affect total and free testosterone?

Not in natties I mean. Only enhanced bodybuilders

I doubt it. In my experience, intermittent fasting doesn't change anything, at least not a 12 hour fast.
It might depend on how long the fast is?

If you're on exogenous test, absolutely not. Taking test smashes all transient changes the body experiences naturally thruout the day.
