Pulse By Legion Athletics

Disclaimer: The following are my views alone. I am not sponsored by Legion Athletics, nor am I being paid by Legion Athletics for this review.

To say that Mike Matthews has come a long way in the Health And Fitness industry would be a gross understatement. In the eight years since the release of his best selling men’s fitness book, Bigger, Leaner, Stronger, he’s parlayed it’s success into his own Fitness empire including his inaugural book’s women’s spinoff, Thinner, Leaner, Stronger, a blog featuring informative, science based articles, an online coaching service utilizing personal trainers hand picked by Mike Matthews himself, and of course his quality supplement line, all under the umbrella of Legion Athletics.


Much like Mike Matthews himself, his products are the real deal. Each product’s ingredients and dosages are determined based on scientific, peer written reviews and journals. You will never find a Legion Athletics supplement containing any filler, artificial sweeteners or secondary bi products to help drive down costs. So don’t be too surprised if Pulse alone might be a tad pricey, but it’s worth it.

Here’s Pulse’s bare bones nutritional profile based on their recently revised formula:

  1. L-Citrulline Malate 2:1 (8g)
  2. CarnoSyn Beta Alanine (3.6g)
  3. Betaine Anhydrous (2.5g)
  4. Caffeine Anhydrous (350mg)
  5. L-Theanine (350mg)
  6. AlphaSize Alpha Glyceryl Phosphoryl Choline(Alpha GPC for short) (300mg)

Just six ingridients make up this profile. But I’d like to turn my attention to Alpha GPC, the latest addition to Pulse’s profile. Replacing L-Ornothine completely and even reducing the amount of Beta-Alanine in Pulse in order to provide balance to this new formula, Alpha GPC, as explained even on Legion’s own website, increases the activity of a chemical in the brain known as acetylcholine, which is used by nerves to communicate with each other, and provides the brain with glycerophosphate, which can improve its health and function. This therefore carries over into:

  • Increase in Growth Hormone Levels
  • Increased Power Output
  • Decrease in age related cognitive decline

Caffeine Dosage

If you’re reading this then you certainly don’t need me or even Mike Matthews to inform you that Caffeine can increase alertness as well as increase the amount of energy your body burns throughout the day. But did you know that the 350mgs found in one scoop of Pulse is actually 20mgs over what’s found in a Starbucks grande? That part I learned from Legion’s website!

That’s personally the most caffeine I’ve ever ingested in any preworkout I’ve ever tried. So is it really necessary? I’d personally say it depends on individual preferences and needs such as your performance goals, the time of day you’re training and whether or not you suffer from anxiety. While some preworkout labels recommend you don’t take anything past a scoop, Pulse recommends that you take two scoops if you know your training is to last more than an hour. That’s 700mgs of Caffeine.

However, the generous dosage of L-Theanine evens out the playing field smoothly, reducing the mental stress that would result from the fight or flight response caffeine usually agitates. Having said that here are a few of the noticeable aspects of Pulse I’ve personally experienced since I began using it in the fall of 2018:

  • Increased Mood – after a long, stressful day of working with kids, followed by a long commute home, avoiding people and hitting the bed are all that matter. But within minutes of taking Pulse, and especially thanks to the 350mg of L-Theanine, I’ve felt nothing short of ready to do just about anything anywhere. I might or might not have become quite the chatterbox.
  • Increased Strength and Endurance – With feeling tired comes that feeling of weakness. It’s hard to progress in the weight room if you’re not feeling strong, or awake for that matter, especially if you train at night as I’d normally do. In fact I dare say I’d never be able to hit my first 400lb deadlift in spite of snowy weather last year without Pulse!
  • No Crash – In fact, I still feel nothing short of energetic even hours after I leave the gym. Although this could be a problem if you take more than a scoop and are training at least four hours before your bedtime.

Final Thoughts

Pulse is without question a preworkout I’d recommend to anyone. It’s the real deal, as I mentioned earlier. Its bare bones profile is the very thing that makes it so effective. It’s equal parts energy without the jitters and focus without the stress. If I had to make a recommendation or two, however, I’d suggest trying their stimulant free alternative if you happen to suffer from anxiety or if you cannot avoid training at night and struggle to sleep afterwards.
