E.S.P from Metabolic Nutrition is a multi-strength stimulating Pre-Workout designed to deliver high-intensity energy unlike any other supplement in the marketplace. Unlike other Pre-workouts that are one dose for all users. E.S.P. is formulated to offer desired energy for low stimulant users, as well as, for high-stimulant users. Additionally, while competing products suffer from short lived or erratic energy levels with questionable taste...E.S.P Pre-Workout delivers consistent sugar stimulated energy for 4+ hours with a flavor profile that will have you craving it before every workout. As with all Metabolic Nutrition products, E.S.P. Pre-Workout is physician formulated and tested using only the highest quality ingredients that have passed our vigorous high standard tests.

Suggested use

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.
