Good old methylenedioxymethamphetamine, where science said “why not” instead of “why” and took methamphetamine and then tweaked it to also dump hella serotonin on top of already having amphetamine properties of stimulating dopamine, norepinephrine, androgens. It’s no wonder people who abuse it can get seriously depressed from burning out literally every pleasure and stimulation neurotransmitter humans have all with one drug. Ain’t your granny’s pep pills
