Important information
Safety Information
Consult your physician prior to using this product if you are pregnant, nursing, taking medication, or have a medical condition. Do not use if seal is broken. Contains caffeine: too much caffeine may cause nervousness, irritability, sleeplessness, and, occasionally, rapid heartbeat. Keep this product and all supplements out of reach of children. Allergen Warning: This product was produced in a facility that also processes ingredients containing milk, egg, soybeans, shellfish, fish, tree nuts, and peanuts
Ingredients
The workout supplement industry is plagued by pseudoscience, ridiculous hype, misleading advertising and endorsements, underdosed products full of junk ingredients, and many other shenanigans. Companies try to dazzle you with ridiculous marketing claims, high-profile (and very expensive) endorsements, pseudo-scientific babble, fancy-sounding proprietary blends, and flashy packaging, and we’ve had enough of it. Legion had to take a unique stand. It had to do what nobody else seems to be willing to do. NO PROPRIETARY BLENDS. We are 100% transparent with what’s in our products, and in what dosages. Not only that, but we back each ingredient with scientific studies that you can review. When you buy a Legion product, you know exactly what you’re getting and why. NO MISLEADING USE OF SCIENCE. We rely only on scientific research that actually applies to our consumers, healthy adults that engage in regular exercise, and we are very careful to not exaggerate findings or make unfounded marketing claims. NO”LABEL FILLER” INGREDIENTS. We have a simple standard that we live by: every ingredient we use must be backed by published scientific literature that demonstrates clear performance benefits. NO UNDERDOSING. We only use ingredients that we can include at clinically effective dosages. That is, the exact dosages shown to be safe and effective in published scientific research. It makes our job harder, and we won’t make nearly as much profit per sale as the “big boys,” but we believe our products will represent a standard by which all others can be judged. And that matters most to us. NO ARTIFICIAL SWEETENERS OR FOOD DYES. While artificial sweeteners and food dyes may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health, and that more research is needed. We’ve chosen to stay on the safe side and use the natural sweeteners stevia and erythritol and leave out the food dyes
Directions
Assess your individual tolerance by mixing 1 scoop with 10 to 12 ounces of water and consume 15 to 30 minutes before exercise. Mild tingling can be expected and is a normal response to beta-alanine, but if you experience any non-optimum effects, stop and consult your doctor. We recommend taking 1 scoop of PULSE 15 to 30 minutes prior to a moderate workout and 2 scoops before an intense workout, especially one that lasts longer than 45 minutes. Product contains caffeine.

Just kidding, that didn't really happen. In all seriousness though, I had a fantastic first experience with this pre-workout. Let me detail what ACTUALLY happened.
I took a scoop half an hour before my back and shoulders workout. Right off the bat, this stuff is delicious. I don't know how Mr. Matthews accomplished this with all natural flavoring but it's terrific. It's a tart fruity flavor (it is fruit punch after all) but it's fantastic. Heck, my previous pre was Cellucor C4 Watermelon and this beats that out even with all the synthetic malarkey. I could see how maybe the taste would diminish if it was watered down too much, be sure to watch how much water you put in since I think I got it just right. Goldilocks'd it, if you will. Yeah that was terrible I know don't judge me.
It was only a couple minutes into my workout that the energy hit. It wasn't a dirty, jittery energy. It was a clean sensation that wakes you up and gets you ready to tackle any workout you have set. I can't quite explain it any other way than it just gives you an unparalleled mental clarity and focus. I busted through every rep at every weight I had planned out; that hasn't happened in a long time. This stuff is just nuts. No pre-workout has ever given me an energy rush like this.
The best part? I mean really the best part? There's no bull with this pre-workout; read the label. It lists EVERY ingredient, and EXACTLY how much of it is in there. My fellow lifters, this is a rarity. Many pre-workouts try to hide behind a proprietary blend. Yeah they have the ingredients, but they have some awkward total of how much stuff is in there without breaking down just how much of each "stuff" is truly present. Mike is setting a new precedent for supplements by, hold on to your pants, giving it to you straight. He has nothing to hide with this supplement and with good reason. He doesn't have to.
The only downside I could possibly think of is the price but you know what? I don't care. It's worth it. Plus two, Mike has to turn in a profit on his product. Honestly, I don't even mind coughing up the cash for this kind of product because you're not paying for JUST the product you're paying for quality and honesty; you can't put a price on either of those. I would compare this pre-workout to buying a Lotus versus, say, a Dodge Ram. Yeah the Ram costs less and has a big V8 and you might be getting more "vehicle" for the money; while yeah the Lotus costs more, you don't get as big of a vehicle, but it's a real driving machine and a feat of automotive engineering. This pre-workout is the Lotus.
I can't recommend this pre-workout enough. I will be keen to try the other Legion supplements. Mike on the chance you read this, I got Bigger Leaner Stronger and The Shredded Chef on the way. You have yourself another fan.
Incase the seller/maker sees this review, I would like to recommend to them selling a few individual sized packets (kind of like Liquid IVs packaging) of multiple flavors to allow people to try their flavors and find out which ones they prefer instead of some people trying one flavor and ditching the whole brand. Other than that you guys are doing great and I look forward to trying Peach and Watermelon.
L-Citrulline Malate
Citrulline is a precursor to the amino acid Arginine, which is a precursor to Nitric Oxide (NO). As demonstrated in a 2007 study, supplemental Citrulline is significantly more effective at raising plasma Arginine than supplemental Arginine itself, and while results with Arginine are mixed, Citrulline has demonstrated clear efficacy as a performance enhancer.
The problem with supplemental Arginine is that it is metabolized in the intestines and liver into other substances such as Ornithine and Urea. The intestines and liver contain relatively high levels of Arginase, the enzyme that converts Arginine to Ornithine and Urea. As a result, very little goes on to be involved with the synthesis of NO because it is being diverted for other purposes. Citrulline, on the other hand, is able to bypass the liver and is metabolized into Arginine elsewhere, where not as much Arginase is present. Thus, more of the Arginine is able to go on to convert into Nitric Oxide.
A 2002 study, published in the “British Journal of Sports Medicine” found that Citrulline Malate supplementation (6g/day for 15 days) significantly increased ATP production during exercise in healthy adult males.
A 2008 study from “The Journal of Strength & Conditioning” found that 8g of Citrulline Malate was able to progressively increase the amount of reps performed later in the workout (by as much as 52%) and significantly reduced muscle soreness.
A 2009 study, published in the “Journal of Free Radical Research”, found that 6 grams of Citrulline Malate given to male cyclists before a race increased “plasma Arginine availability for NO synthesis and PMNs priming for oxidative burst without oxidative damage”.
A 2011 study, the subjects of which were rats, found that supplemental Citrulline increased muscular contraction efficiency (less ATP was required for the same amount of power), in-line with the findings of the above-mentioned human study.
Citrulline is generally considered to be most effective at doses of 6-8g, though it is rare to find that much in pre-workout supplements (it gets kind of expensive). Pulse contains a highly effective 8 gram dose of Citrulline (as Citrulline Malate) per serving, consistent with the dose used in the above mentioned 2008 study and beyond that used in most other studies.
Beta-Alanine
Beta-Alanine is a precursor to the amino acid Carnosine, which functions as a lactic acid buffer capable of reducing fatigue in the working muscle. Though it takes time to accumulate in muscle tissue, Beta-Alanine supplementation, for at least two weeks, is highly effective at increasing muscular Carnosine concentration.
One study in particular that measured the Carnosine levels of sprinters found that individuals with higher muscular Carnosine levels exhibited higher power output in the latter half of a 30m sprint (because they had less lactic acid build-up). Multiple studies have confirmed that Beta Alanine supplementation increases muscular Carnosine in a dose dependent manner. In particular, a 2012 study published in “Amino Acids” found that subjects who consumed 1.6 or 3.2 grams of Beta Alanine daily experienced significant increases in muscle carnosine in as little as two weeks, with the higher dose achieving a higher concentration of Carnosine. The doses used in this study, 1.6 and 3.2g, are the most common doses seen in supplements.
A 2008 study, published in the International Journal of Sports Medicine, noted improvements in power in resistance trained males using 4.8g daily for 30 days. This same 4.8 gram dose was also shown to increase muscular endurance in sprinters in a 2007 study from the “Journal of Applied Physiology”. Generally speaking, the highest dose used in most pre-workouts is 3.2g because that is, after all, an effective dose. However, Legion has gone the extra mile with Pulse by including 4.8 grams of Beta-Alanine per serving, in-line with the highest, most effective dose used in studies, and more than we’ve ever seen in any pre-workout.
Betaine Anhydrous
Betaine (also known as Trimethylglycine) is the amino acid Glycine with the addition of three methyl groups attached. Betaine is alleged to increase power output and strength by increasing cellular swelling, a phenomenon well established with Creatine supplementation, which can drastically reduce the damaging effect of outside stimuli (such as exercise) on the working muscle. So far, Betaine has been investigated in several human studies, and has had some pretty encouraging results in most.
A 2009 study, published in the “Journal of the International Society of Sports Nutrition”, found that 2.5g Betaine (split into two 1.25mg doses) over the course of 15 days increased muscle endurance during squats and appeared to improve the quality of each rep (likely because they were easier).
A 2010 study, again from the “Journal of the International Society of Sports Nutrition”, found that the same supplementation protocol (2.5g daily in two equal doses) effectively increased isometric bench press and squat force as well as bench throw and vertical jump power.
A 2011 study, published in “The Journal of Strength & Condition Research” noted improvements in number of bench press repetitions and total volume load with same 2.5g dosing protocol for 14 days. However, another 2011 study from the same journal noted no such improvements in power output or number of reps performed, though there were subjective reports of fatigue reduction.
A 2012 study from the “Journal of the International Society of Sports Nutrition” noted improvements in cycling sprint power after just one week of supplementation at the standard 2.5g dose.
Most recently, a 2013 study published in the Journal of the International Society of Sports Nutrition” noted increases in arm size, bench press work capacity, overall body composition, and a trend toward increased power (but not strength). This was the first study to specifically measure the effects of Betaine supplementation on body composition, so further study is needed to corroborate these findings.
Pulse contains the standard dose of Betaine used in the above mentioned studies of 2.5g, a highly effective amount which eliminates the need to take two daily doses.
Ornithine
Ornithine is an amino acid used alongside Arginine and Citrulline in the Urea Cycle, the process by which Ammonia is metabolized into the harmless substance Urea. Prolonged exercise generally brings about increases in Ammonia, which causes fatigue in the working muscle after enough has built up. As evidenced in a 2010 study published in the European Journal of Clinical Nutrition, supplemental Ornithine, at a dose of 100mg/kg, has failed to influence fatigue in short duration exercise. However, a 2008 study from “Nutrition Research” noted a significant reduction in fatigue during prolonged exercise in healthy volunteers who consumed 2g Ornithine daily for 6 days and 6g prior to testing. Unfortunately, because of the structure of this study, it is unclear whether Ornithine requires “build-up time” or if acute supplementation is effective. Either way, it appears Ornithine will only be noticeably effective during prolonged exercise, when Ammonia would usually cause fatigue. Pulse contains 2200mg of L-Ornithine, much more than the average Ornithine-containing pre-workout which may be somewhat synergistic with the hefty dose of Citrulline that Legion has also packed into the Pulse formula.
Theanine
In a 2008 study, published in “Nutritional Neuroscience”, researchers investigated the cognitive effects of a combination of Theanine and Caffeine compared to Caffeine alone on various measures of cognitive performance. Participants received either 50mg of Caffeine or 50mg of Caffeine and 100mg of Theanine before completing various tasks including word recognition, visual image processing, and attention switching. While Caffeine was able to increase alertness and accuracy during the attention switching tasks, the combination of Caffeine and Theanine was able to improve both performance and speed, while reducing the subjects’ susceptibility to distraction.
Another 2008 study from “Biological Psychology” found that, while 150mg of Caffeine increased alertness and improved (decreased) reaction time, adding 250mg of Theanine further improved reaction time, alertness, and decreased the number of headaches reported from Caffeine.
A 2010 study, also from “Nutritional Sciences”, found that the combination of 97mg of Theanine combined with 40mg Caffeine significantly improved focus and attention on various cognitive tests, compared to placebo.
Another 2010 study, this one published in “Appetite”, noted an improvement in task-switching ability using the same 97mg Theanine/40mg Caffeine combination.
Theanine is, in our view, a very under-utilized ingredient in pre-workout supplements these days. Despite a well-established synergistic relationship with Caffeine, supplement companies seem reluctant to include Theanine in effective doses mostly because of cost issues (it is relatively expensive). However, Pulse contains a highly effective 350mg of Theanine to go alongside the 350mg of Caffeine.
Caffeine Anhydrous
Caffeine is a well-established ergogenic aid, oral consumption of which triggers the release of Catcholamines (Noradrenaline, Dopamine, Adrenaline, etc.), generally inducing a state of increased alertness, focus, and perceived energy. A vast multitude of studies have concluded that Caffeine consumption prior to exercise can favorably impact performance and enhance muscle contractibility.
Since habitual Caffeine consumption often leads to tolerance build-up, those seeking to get the most out of their Caffeine-containing pre-workout should limit Caffeine throughout other parts of the day. Pulse contains 350mg of Caffeine which is enough to make even a somewhat Caffeine-tolerant individual feel noticeably more focused and alert. Though 350mg would normally be considered “jitter territory”, the 350mg dose of Theanine present in the Pulse formula may partially (if not completely) reduce the likelihood of the Caffeine causing any negative effects.
