Pumps are back. L-citrulline dose is right. I skipped the jittery pre-workout scene and this does the job without the crash.

Citrulline + arginine stack for circulation, pump, and endurance
Clinical-dose precision. No taste, no mixing, no fuss.
Right ingredients, wrong dose. Citrulline studies use 6-8g for endurance and 3g for pump. This ships 400mg, so you'd need a half-dozen capsules to hit study doses. Use this as part of a stack, not as your sole pre-workout.
Build the habit. Skip any month.

Endurance runs noticeably easier. No caffeine, no artificial colors. Two caps 30 min pre-run is the sweet spot.
