I googled some pre-workout and it seems to be about 200mg of caffeine, same as a can of Monster. I've drank 2 cans of Monster back-to-back a few times in my life and still not felt jittery.

I largely share experience with Kiro, I don't feel like caffeine makes me perk up at all really. I just drink Monster cause I love the flavor of some of them.

I'm the same. I've taken caffeine pills and not noticed it. I can also just drink tea/coffee and then sleep.

200mg, I feel nothing. 300mg, my heart races some, but still no jitters or anxiety.
