The Science of Amino Z Stim Pre-Workout
Amino Z Stim Pre-Workout was meticulously researched and crafted,
bringing you a unique formula based on real science.
Triad Stimulant Blend: Amino Z Stim Pre-Workout combines three of the
best stimulants – Caffeine Anhydrous, N-Methyltyramine, and Higenamine –
to deliver a well-rounded boost of energy for muscle and mind alike.
Caffeine has long been regarded as the foundational pre-workout
ingredient as it has been shown to improve focus, reaction time, and
sports performance. (1)
A citrus tree alkaloid, studies found that N-Methyltyramine was able to
significantly improve reaction-based performance, focus, and overall
energy levels. (2)
A traditional herbal extract found in Chinese medicine, Higenamine
increases performance by promoting stored fatty acids as fuel and
increasing focus much like caffeine. (3)
Beta Alanine (3200 mg.): An amino acid that causes a characteristic
tingling sensation in your neck and face, beta alanine is a pre-workout
staple. It has been shown in a variety of studies to increase
strength-based performance levels and overall energy. (4)
L-Tyrosine (1500mg.) This amino acid is a natural way to significantly
increase cognitive performance and focus while lifting mental fog. As a
pre-workout ingredient, L-tyrosine can improve reaction time and mental
performance during training. (5)
Citrulline Malate (6,000 mg.): Popular among athletes and natural
bodybuilders, citrulline malate can increase energy and overall strength
output. One study found that those using citrulline malate saw an
increase of up to 52% in anerobic performance. In that same study,
subjects reported a 40% reduction in muscle soreness within 24 hours.
