What is MP Assault pre-workout?
MP Assault is MusclePharm’s Assault Pre-Workout powder. The current Fruit Punch label identifies a 30-serving product with 250 mg caffeine per scoop. This guide covers that standard powder, rather than treating every product carrying the Assault name as the same formula.
What is in one serving?
The manufacturer’s Fruit Punch label specifies one 11.5 g scoop:
- Creatine monohydrate: 3 g
- Beta-alanine: 1.75 g
- Betaine anhydrous: 1.5 g
- Taurine and L-glycine: 1 g each
- Caffeine anhydrous: 250 mg
- Acetyl-L-carnitine HCl: 250 mg
- Vitamin C: 300 mg; vitamin E: 36 mg; vitamin B6: 20 mg; vitamin B12: 50 mcg; calcium: 40 mg
The photographed panel lists no citrulline. Its named ingredient groups show individual amounts, so the group headings should not be mistaken for undisclosed proprietary blends.
How to interpret the formula
Assault combines caffeine with creatine and beta-alanine. These are different buying considerations: a noticeable stimulant effect does not establish better recovery or muscle growth. NIH’s exercise-supplement overview explains that creatine’s training benefits develop with repeated use; beta-alanine studies also typically involve weeks of supplementation. Do not increase Assault servings to chase a separate ingredient target.
Directions and cautions
MusclePharm’s directions call for one scoop in 8–12 fl oz of cold water, 20–30 minutes before training, with a maximum of one serving daily. The pictured label warns that it contains milk, egg and soy lecithin and lists additional facility cross-contact risks.
Count caffeine from other drinks and supplements. The FDA notes substantial variation in caffeine sensitivity; anxiety, palpitations or disrupted sleep are reasons to reassess use rather than add more.
Bottom line
Assault is a clearly dosed, caffeine-containing formula with creatine monohydrate and no listed citrulline. Compare the actual scoop size, caffeine and ingredient forms on your tub. Neither the brand name nor the strength of the immediate sensation proves it will outperform another product.
