MuscleTech Shatter Extreme Energy and Performance Amplifier Pre-workout Powder is designed to enhance energy, mental focus, and overall workout performance. MuscleTech Shatter Extreme Energy and Performance Amplifier Pre-Workout Powder is formulated with 3.2g beta-alanine, 2.5g betaine, 350g caffeine &, 4g citrulline plus citrapeak & NO3-T. Also features a dual-sourced dose of choline and L-theanine. Beta-Alanine (3.2g) is known for supporting carnosine levels in the body, which helps reduce lactic acid buildup. This, in turn, may decrease fatigue during intense training, leading to better muscle performance. Betaine (2.5g) found naturally in the body, as well as in beets and spinach, betaine has been studied for its potential to increase muscle mass. The mentioned dose of 2.5g was shown to significantly contribute to muscle gain in a 6-week study compared to a placebo group. Citrulline (4g) is an amino acid that converts into L-arginine in the body, leading to increased nitric oxide production. This can enhance vasodilation, promoting better blood flow and intense muscle pumps. The formula also includes CitraPeak™ and NO3-T® red spinach extract for additional nitric oxide support. Caffeine (350mg) is well-known for its stimulating effects; caffeine enhances energy levels and mental focus. This dose is relatively high and can provide a significant boost for strenuous workouts. Choline and L-Theanine are ingredients contribute to the neurosensory effects of the formula. Choline is a precursor to acetylcholine, a neurotransmitter associated with focus and cognition, while L-theanine can have a calming effect and potentially mitigate the jitteriness associated with high doses of caffeine.
