You just like to be the nay saying type don't you? No kidding they aren't the same thing, neither is a mouse and a human lol. The point is, you're using a blanket statement of "You're microdosing" as if that's some valid argument for it not working. Who says 10mg shouldn't be a standard dose? It's one study where they decided to give X amount. It's new, so therefore there is no standard.
I don't need to keep time trial data, I can go by how I feel much like if you took 400mg of caffeine, I'm sure you would feel that. By your analogy, only taking 100mg of caffeine would be microdosing, but guess what, you'd still feel it.
