The only substances I would for sure be concerned about are finasteride and dutasteride. The others, IDK for sure, but those two, yeah, I would be careful with.
When I am on finasteride and need to donate, I stop taking it for a week to 10 days, to let it clear my system. It's half life is 24 hours or so.
Note that I DO donate when I'm blasting, so I am for sure no blood cop lol
