How long does a benzedrex/propylhexedrine high last?

About 3 hours ago I ate 2 cottons (500mg) and I'm still feeling good. how long does it last before the comedown?

I'd say you've got a good 6-8 hours.

I'd say you've got a good 6-8 hours.

From now or from when I took them?

I would say that once it's kicked in you've got about 6-8 hours of desired effects and then a few more hours of stimulation.
I'm sure it can vary between people as well.
