You've probably figured it out by now, but you don't need that much, you need to get somewhere around ~60 times can cum first, then you'll randomly get a scene where Anon goes to the toilet confused to see that his pee is white, after this scenes your cum max will decrease, so you'll have to increase it again. For the bad end scene, I got it shortly after reaching 70 times can cum, I just sat there in the room as a couple of minutes went by and it triggered, I never had to frick or anything to get either of these scenes. It really shouldn't take that many Endurance pills to get to this point, just take the pill, spend some time walking outside until you're very healthy again, and take it again. You can technically reach this ending even without the Endurance stuff, since prickled onions do slightly increase cum max as well (I've reached the ending this way without taking drugs), but it takes too many pickled onions to reach that point.
