The only stimulant in Legion Pulse is caffeine and there are only 350mg per serving (2 scoops). That’s about the same as a “Grande” coffee at Starbucks. There are no “harsh” stimulants or anything in Pulse that will make your stomach upset or make you jittery.
That being said, some “tingling” can occur due to the beta alanine inside of Pulse. I’ve found that effect to go away (or at least minimize) after a couple of weeks.
Here’s what Mike says about Pulse and the entire message behind PULSE:
I go more over everything about Pulse in my Legion Pulse Review (also, if it has creatine and which flavor is best), however, I wanted to point out this one quote from his Pulse sales page about the creation of his pre-workout:
“And last but not least, we wanted no upset stomachs, nausea, or other undesirable side effects”
He starts comparing his pre-workout to the competition which has harsh chemicals and stimulants inside. These types of ingredients can cause crashing, upset stomachs, jitters, and nausea before, during, and even long after the workout.
That’s the reason why there are only 350mg of caffeine in Pulse per serving. Let’s look a little bit closer into why such low caffeine is warranted in a Pre-Workout supplement.
Pulse can get away with such low caffeine because of its combination with L-Theanine (more on this in a second).
Caffeine is the world’s most used drug. It helps you get or stay awake, improves energy, strength and many more things. It can also help you lose weight.
“The clinically effective dose of caffeine for enhancing performance is between 3 and 6 milligrams per kilogram of body weight.”
Pulse is right on the lower end and contains 350 milligrams of caffeine per serving.
L-Theanine, “when paired with caffeine, improves mood, memory performance, and attention.”
For this reason, Pulse does not need as much caffeine as other pre-workout supplements and still gives you a smooth energy rush.
