Mixed half a scoop into my intra-workout shake instead of pre-workout and honestly didn’t feel jittery, just steady endurance through the last sets. The dosing flexibility for stim-free days is a nice touch, and it dissolved clean without that chalky residue.

The serving size is easy to measure and the 15-30 minute pre-workout window works perfectly for me—I feel it kick in right as I hit my first heavy set. Directions are simple enough that I don't have to think twice before mixing it into my shaker.

I’ve been taking this as directed with my pre-workout about 20 minutes before lifting, and the timing actually seems to make a difference in how steady I feel through the whole session. Mixing one serving into my intra drink for endurance days works just as well, no jitters.
