Pre Stack Extreme Reviews

*L-Citrulline Malate 2:1 (8 grams): L-Citrulline Malate is an amino acid compound that plays a role in the urea cycle, which helps remove ammonia from the body. It is commonly used in pre-workout supplements due to its potential benefits in improving exercise performance. L-Citrulline Malate may increase nitric oxide production, which can enhance blood flow and oxygen delivery to the muscles. This, in turn, may reduce fatigue and improve endurance during workouts. The 2:1 ratio refers to the combination of L-Citrulline and malic acid in the supplement.

*Beta Alanine (4.4 grams): Beta-alanine is another amino acid that helps increase muscle carnosine levels. Carnosine acts as a buffer, reducing the accumulation of lactic acid in muscles during high-intensity exercise. By buffering lactic acid, beta-alanine may delay the onset of fatigue and improve performance in activities that require short bursts of intense effort, such as weightlifting or sprinting.

*CDP Choline (300 mg): CDP-choline, also known as citicoline, is a compound that can enhance cognitive function and improve focus and concentration. In a pre-workout context, it may help enhance the mind-muscle connection, allowing for better control and coordination during workouts.

*Methylxanthine Anhydrous (Caffeine) (300 mg): Caffeine is a well-known stimulant that can increase energy levels, reduce fatigue, and improve alertness. It acts by blocking adenosine receptors in the brain, which helps promote wakefulness and delay the onset of tiredness. In a pre-workout supplement, caffeine may enhance physical performance and endurance while reducing the perceived effort during exercise.

*N-phenethyl dimethylamine (Eria Jarensis) (125 mg): Eria Jarensis is a plant extract that contains N-phenethyl dimethylamine, a compound known for its potential mood-boosting effects. It may contribute to a positive mental state and enhance motivation during workouts.

*Juglans Regia: Juglans Regia, commonly known as English walnut, is a nut extract that may provide additional cognitive and energy-boosting effects. However, without more specific information, it is challenging to provide further details about its potential benefits or mechanisms of action in a pre-workout context.

*BioPerine (piper nigrum fruit extract) (5 mg): BioPerine® is a patented extract derived from black pepper fruits (piper nigrum). It contains piperine, a compound that can enhance the bioavailability and absorption of other nutrients and supplements. In a pre-workout supplement, BioPerine® may improve the uptake and utilization of the other ingredients present in the formula.

*Huperzine-A (300 mcg): Huperzine-A is a natural compound derived from the Chinese club moss plant. It is known for its potential cognitive-enhancing properties and may help improve focus and concentration during workouts. Huperzine-A has also been suggested to enhance muscle contractions when stimulated by nerves, potentially leading to improved muscle performance.
