Ingredients & benefits
Musashi has gone heavy on clinically researched ingredients designed to amplify energy, pumps, and mental performance. Each scoop of Reaper Pre-Workout Max Strength includes:
- Electrolytes – support hydration, nerve function, and muscle contraction to maintain peak performance during intense training.
- Creatine Monohydrate – enhances muscle strength and power output, supporting explosive lifts and endurance.
- Beta-Alanine – helps buffer lactic acid, delaying muscle fatigue for longer, harder training sessions.
- Choline Bitartrate – enhances focus and mental clarity by supporting neurotransmitter function for improved mind–muscle connection during workouts.
- Caffeine – a high-stim energy hit that increases alertness, focus, and drive.
- Acetyl L-Carnitine – enhances energy production and endurance by transporting fatty acids into the mitochondria for fuel during workouts.
- Tyrosine – boosts cognitive function and stress resilience, helping maintain focus under fatigue.
- Alpha GPC – boosts mental focus and power output by increasing acetylcholine levels, supporting both cognitive performance and muscle contraction.
- Citrulline Malate – promotes nitric oxide production for improved blood flow, better pumps, and nutrient delivery.
- AAKG – enhances nitric oxide production to promote stronger muscle pumps, improved blood flow, and better nutrient delivery during workouts.
- Ornithine – helps reduce fatigue and support endurance by assisting in ammonia removal during intense training.
Together, these ingredients form a high-performance matrix that supports the full training spectrum, energy, endurance, strength, and mental drive.
