Caffeine

PLEASE NOTE: Caffeine serving is either in three 100mg capsules, or three round tablets, depending on supply available at time of production. Please also note that the capsules are very similar to L-Theanine, with a mildly discernible visual difference.
Most energy drinks contain between 160-350mg of caffeine, and coffees at Starbucks can have up to 475mg sans that extra Espresso shot! NatStacks have a safe amount of 300mg caffeine per stack pack, what most energy drinks have, with the main difference being the other supportive nutrients that maximize, and sustain its ergogenic properties efficiently without the crash hours later.
