There's a trick to it. You have to take the anaphrodisiac and then instantly Expose yourself so that the sqoids stick to your head. That will make it so you lose lust as you gain it, letting you squeeze about 8 or 9 hypnos per heart. I recommend playing on Casual cause it took me 35 waves before I could actually manage to do it, because you can only let yourself get hypnotized once per anaphrodisiac use, otherwise your lust explodes like crazy and it'll be impossible to get 15.
As for the dodge one, it's weird. It doesn't track them very well, from my experience. I think I dodged more than 100 before the experiment procced, but that means that it is doable. Just a major pain in the ass. My recommendation is what you said, keep 3 alive by the end of the wave and keep dodging until you count 30 or something, kill them, and then do it again another wave. I think there's a limit to how many times you can advance the experiment from 1 squoid, but like I said, it might just be a problem of the game not tracking them well.
