Take before high-intensity, shortduration exercise (less than one hour). Dissolve 1–4 tablets under your tongue 5–30 minutes before the start.
For prolonged exercise, dissolve 1–3 tablets under your tongue, as needed before climbs or other strenuous efforts and whenever you desire a quick boost of energy.
To accelerate absorption, chew tablets, but do not swallow. Hold chewed-up tablets in your mouth for 1-5 minutes before swallowing.
