I've been dabbling in strong preworkouts over the last few months. Started with Gorilla- can't recommend-, Total War- better than a cup of coffee-, both bought brick and mortar locally. Wanted some preworkouts that were a bit stronger.. looked online.. found nutracartel. Ordered Maniaco, Ronin, El Jefe Fuego/El Jefe/El Jefe Neuro. Placed another order a bit later for Mr. White, Doomsday, Wrecked Enraged, Crack OG, Legit. What I'll say about Maniaco is that it's a solid hitter that didn't mess with my stomach, have me totally tweaked and shaking like Wrecked/Crack/Legit, felt a bit more driven and euphoric. That good feeling will last throughout the day. Maniaco does provide some good power, recovery, feels. This isn't a daily, but a treat that i like to space out once every four or five days. Good stuff!
