That was around the time that we restructured our whole line-up. IMO, they are quite different products. I still have some Chaos that I kept vacuum sealed. For me, it's like an energy drink. IMO, Maniac is better suited if you're looking for endurance and focus.
I think they could both exist in the line-up at the same time if some minor changes were made. I would take the small amount of caffeine in Maniac out and have it as our stim-free pre-workout. I'd maybe make some minor changes to Chaos, but leave all of the caffeine, guarana, rhodiola, etc in it. That's just my opinion, but I almost never go to the gym at the same time two sessions in row. Sometimes it's in the morning when it opens and other days I'm that A-hole that stays until I get kicked out :lol:
