Caffeine is one of the most tested ergogenic aids.  Having over 70 good studies related to athletic performance; caffeine is a well-known stimulant that can enhance your workout in many ways. 


It boosts strength and fatigue tolerance, decreases perceived effort (which greatly improved exercise performance), increases power output, and produces a worthwhile enhancement of short-term endurance performance.  It activates the nervous system to improve focus and energy while reducing tiredness and also increases thermogenesis which helps to burn calories.

Clinically effective dosages range between 3-6mg/kg of body-weight and Primed Intensity contains 350mg of caffeine per serving.

L-theanine is an amino acid found primarily in tea and while it is a popular standalone supplement, it has a special synergistic relationship with caffeine


L-theanine can delay exercise-induced fatigue and promote nitric oxide production for improved blood flow and oxygen delivery to your muscles; however, L-theanine's unique contribution is its ability to affect brain function.  It can reduce mental and physical stress, improve focus, improve overall cognition, improve mood and improve mental performance.

If that wasn't enough, it has also been shown to improve sleep quality and boost immune function.

Most studies show benefits in the range of 100-200mg of L-theanine but when taken with caffeine the ratio is closer to 1:1.  Primed Intensity contains 300mg of L-theanine per serving.


Primed Intensity uses Carnosyn® beta-alanine and provides a clinically effective dosage of 3.6 grams per serving.  Scientific studies prove that beta-alanine increases the working capacity of muscles if you take at least 90 grams over a 28-day period (an average of 3.2 grams per day).
