Metabolic Nutrition E.S.P. Extreme – Maximum Strength Stimulant Pre-Workout

E.S.P. Extreme is formulated to be one of the strongest, highest-energy pre-workouts on the market — built for people who need higher-potency stimulants to maximize performance, energy, and strength training. Its unique multi-dose scoop system lets you dial in the exact intensity you need, from a first-timer's assessment dose to a max-tolerance, advanced-athlete dose.*

Why lifters choose E.S.P. Extreme

• Scalable caffeine dosing — 1 scoop delivers 250 mg caffeine, 2 scoops deliver 500 mg, and 3 scoops (the max) deliver 750 mg
• Multi-source stimulant blend built around caffeine anhydrous, theobromine, and di-caffeine malate for fast onset plus extended energy
• Focus and mental drive from choline bitartrate, N-Acetyl-L-Tyrosine, and Eria Jarensis
• Beta-Alanine included to help buffer lactic acid and support training endurance
• Customizable small-scoop / large-scoop system so you control your own dosing rather than a fixed serving

How do you use E.S.P. Extreme?

Due to its strength, start with one serving (1 small scoop) mixed with 6 fl oz of water, 20–30 minutes before training. Once you've assessed tolerance, you may increase to 2 level small scoops with 10–12 fl oz of water. With caution, advanced athletes tolerant of high stimulants may take 1 level large scoop with 16–18 fl oz of water. Do not exceed one large-scoop dose (3 servings) in any 24-hour period, do not combine with other caffeinated products, and do not consume as a dry powder.

Who is E.S.P. Extreme for?

Healthy adults, 18 and older, with an established tolerance for high-stimulant pre-workouts who want a scalable dosing system rather than a fixed scoop.
