Jonathan: You’re right! It’s kind of true about everything. Yes, it will take personal experimentation and common sense. But “trying to establish a baseline” by asking a question on a forum is hardly the best way to establish a baseline! It’s a great way to get all screwed up. Listen to the podcast and read the literature. Coach Chad has reviewed it multiple times. Trolling for a whole bunch of N=1 anecdotes is hardly the best way to find a “starting point.” Stabs in the dark would actually be better. A better question would be to ask how one should establish a good experimental design for determining your best caffeine supplementation.
