Analysis updated August 2026 · How Scout scores
At a glance
Summary
This pre-workout supplement contains beneficial ingredients such as citrulline, beta-alanine, creatine, and BCAAs, which are known to enhance exercise performance and muscle recovery. However, the presence of an emulsifier and the lack of transparency regarding the specific type and amount of caffeine used slightly detract from its overall formulation quality. The product is moderately processed, but it does not contain artificial sweeteners or dyes, which helps maintain a relatively high score.
Key ingredients 9
CreatineVery Good
Creatine is a well-researched supplement known for enhancing strength, power, and muscle mass. It helps regenerate ATP, the primary energy carrier in cells, during high-intensity activities. This can lead to improved performance in short bursts of intense exercise.
Benefits
Creatine supports increased muscle mass, strength, and exercise performance.
CitrullineGood
Citrulline is known for enhancing blood flow and improving exercise performance. It is a non-essential amino acid that converts to arginine and then to nitric oxide, which helps in vasodilation. This can lead to improved oxygen and nutrient delivery to muscles during workouts.
Benefits
Citrulline may help reduce muscle soreness and improve endurance during high-intensity exercise.
Beta AlanineGood
Beta Alanine is beneficial for increasing muscle carnosine levels, which can enhance exercise performance. It helps buffer acid in muscles, reducing fatigue during intense workouts. This can lead to improved endurance and strength.
Risks
High doses may cause a harmless tingling sensation known as paresthesia.
Benefits
Beta Alanine can improve performance in high-intensity exercise and delay muscle fatigue.
Branched Chain Amino AcidsGood
Branched Chain Amino Acids (BCAAs) are essential nutrients that help support muscle protein synthesis and reduce muscle breakdown. They consist of leucine, isoleucine, and valine, which are crucial for muscle recovery and growth. BCAAs can be particularly beneficial during and after workouts to enhance recovery.
Benefits
BCAAs can help reduce muscle soreness and improve recovery after exercise.
L-LeucineGood
L-Leucine is a key amino acid in promoting muscle protein synthesis and muscle growth. It is one of the three BCAAs and plays a critical role in muscle recovery and repair. L-Leucine is often considered the most important BCAA for muscle building.
Benefits
L-Leucine supports muscle growth and recovery, making it beneficial for athletes and bodybuilders.
L-IsoleucineGood
L-Isoleucine is an essential amino acid that aids in muscle recovery and energy production. It is one of the BCAAs and helps regulate blood sugar levels and energy levels during exercise. L-Isoleucine is important for muscle repair and endurance.
Benefits
L-Isoleucine can enhance endurance and aid in muscle recovery after exercise.
L-ValineGood
L-Valine is an essential amino acid that supports muscle metabolism and tissue repair. It is one of the BCAAs and helps maintain nitrogen balance in the body. L-Valine is important for muscle growth and energy production.
Benefits
L-Valine aids in muscle growth and repair, making it beneficial for athletes.
CaffeineNeutral
Caffeine is a natural stimulant that can enhance alertness and improve exercise performance. It is commonly used to increase energy levels and focus during workouts. Caffeine from natural sources is generally considered safe in moderate amounts.
Risks
Excessive consumption may lead to jitteriness, increased heart rate, and sleep disturbances.
Benefits
Caffeine can improve focus, energy, and endurance during workouts.
EmulsifierNeutral
Emulsifiers are used to stabilize and improve the texture of products. They help mix ingredients that typically do not blend well, such as oil and water. The specific type of emulsifier used is not identified, so it is considered neutral.
Benefits
Emulsifiers improve product consistency and stability.
