📋 Directions for Use

1 Dose Daily Use with Caution Assess Tolerance First

Directions: Due to the strength of E.S.P. Pre-Workout please assess your tolerance by initially taking only 1 level serving of the small scoop with 5 oz of water 15 minutes prior to your workout. After assessment of your tolerance, if you require further energy stimulation, you may increase to 2 level small scoops with 10 oz of water...and once again access your tolerance. With caution, for maximum extreme energy release for advanced athletes or persons tolerant of high energy stimulants...you may take 1 level large scoop with 16 oz of water. Do not exceed one large scoop dosage in any 24 hour period. Do not take 4 hours prior to desired bedtime.
