Just wondering what you guys prefer when it comes to either nootropics or a even a pre-workout.
Lately I've noticed caffeine seems to stress me out more than coffee, even when the caffeine content is more or less the same. It is nice to start the day with a stimulant but I feel like getting stressed out is the opposite effect I'm trying to achieve with nootropics.
I also read a study recently - The metabolic and performance effects of caffeine compared to coffee during endurance exercise. - that suggests that coffee and caffeine are equal in terms of exercise performance (at least, for endurance), but that caffeine has different metabolic effects than coffee, even when caffeine content is the same (5 mg/kg bw). Caffeine increased serum glycerol and lactate more significantly than coffee did.
Perhaps a reason for this is a larger increase in cortisol, or catecholamines such as epi/norepinephrine from the caffeine.
