Genius green apple pre-workout powder

Never used a pre-workout before--interested in trying something that didn't taste like garbage, wasn't highly caffeinated, and possibly organic. Liked the idea of a nootropic (positive experience a long time ago) Taste was tart (not a bad thing), not 100% sure if it's making a difference. I did hit a couple PR's, but unsure if intensity of workouts masked any real effects
