PER4M Energy Pre Workout 390 g is a stimulant-containing pre-workout powder developed for adults looking for a compact formula combining citrulline malate, beta-alanine, taurine, L-tyrosine, caffeine, theobromine, botanical extracts and niacin.
Each 6.5 g serving provides 2500 mg of L-Citrulline DL-Malate 2:1, 1600 mg of beta-alanine, 500 mg of taurine and 500 mg of L-tyrosine.
The stimulant component provides 200 mg of caffeine anhydrous together with a cacao-derived theobromine ingredient. The supplied Supplement Facts describe this as “Theobromine (20% Cacao Extract) – 100 mg”; because this wording can be interpreted in more than one way, the exact quantity of actual theobromine should be confirmed from the current product label before stating a specific theobromine dose.
The formula also contains 100 mg of African Mango Extract 4:1, 25 mg of Grains of Paradise Extract, 25 mg of niacin as niacinamide and 2.5 mg of BioPerine® black pepper extract.
With 200 mg of caffeine per serving, PER4M Energy is best suited to adults who are comfortable using caffeinated pre-workout products and who can appropriately account for caffeine from coffee, energy drinks and other supplements.
One 390 g container provides 60 servings, with one scoop mixed into approximately 150 ml of water and consumed 15–30 minutes before exercise.
