Review: Power Level Over 9000 - Alright, so I took a scoop of this pre-workout before my back and shoulders session. Immediately, I felt a Saiyan-like surge of energy. My hair instantly grew another foot, turned bleach blonde and formed spikes. I took off like a rocket, left a human sized hole in multiple walls at work and crashed through Planet Fitness. Naturally, this set off the lunk alarm, which I then proceeded to rip off the wall, throw through the roof, and incinerate it in a blast of energy bright enough to be seen from Neptune. I then did shoulder presses with a pretty girl in each hand. 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.

The transparency of the product's label is commendable. LEGION provides full disclosure of all ingredients and their dosages, allowing me to make an informed decision about what I'm putting into my body. Another standout aspect of this pre-workout is its versatility. I can easily adjust the serving size based on my energy needs for the day. On days when I need an extra boost, I take a full scoop, and on lighter workout days, half a scoop suffices. As a fitness enthusiast, I prioritize my health and well-being. The fact that LEGION Pulse is free from banned substances and third-party tested for purity and potency provides me with peace of mind, knowing that I'm using a safe and reliable product.

## Questions & Answers

**Q: How can you claim to have no artificial junk, when maltodextrin and "natural and artificial flavors" are listed on the label?**
A: Good question!There is less than 1 gram of malto per 20-gram serving to cut the bitterness of the amino acids and to help with clumping. Regarding the flavoring, natural flavoring means just that--not MSG (which wouldn't make sense in a product like this anyway). Before launching the line, I did quite a bit of research on artificial flavoring and couldn't find any valid, science-based reason to avoid it completely (not a single clinical indication of negative interactions in the body). Artificial sweeteners, on the other hand, are another story--there's a growing body of evidence that regular consumption can indeed harm our health. All that said, I'm actually working on switching it to 100% natural flavoring just because. :) It just takes a bit more time with this product because masking the bitterness of the aminos WITHOUT artificial sweetener or tons of malto is tough.Hope this helps!MikeFounder of LEGION

**Q: I found huge clumps of the powder lumped together (not while mixing in water) in the tub. Tried shaking tub, no luck. Whats up?**
A: DECEMBER 8 2014 UPDATE:Hi,I'm Mike, founder of LEGION, and I just wanted to give you, the customer or potential customer, an update on the clumping issues we were having with the fruit punch flavor of Pulse.Citrulline malate is an extremely hygroscopic amino acid, which means it absorbs moisture, and when used in a pre-workout, it's combined with a small amount of another ingredient to prevent this, like silica.As Pulse contains 8 grams of citrulline malate per serving, it can clump very easily, and our manufacturer conveniently forgot to take anti-clumping measures with several thousand fruit punch bottles that we ordered. As they then sat on the shelf, waiting to be sold, they began to clump up. Some become rock hard.We didn't realize this until it was too late--until customers were contacting us and leaving negative reviews. Once we found out what was going on, we promptly disposed of the clumped bottles.We've also made very sure this will never happen again, and we've sent new, clump-free bottles to everyone that has contacted us about the problem.So if you're considering trying Pulse but are worried about the clumping, you can rest easy knowing that this is no longer an issue, and even if it were, we would go out of our way to take care of you.Sincerely,MikeFounder of LEGION

**Q: How does it compare to C4?**
A: C4 is for beginners. It's weakly dosed and overall just an average product for anybody who's been lifting for a while and/or been ingesting caffeinated products quite frequently. I used it to start out and it quickly (maybe a month at most) became obsolete to the point I'd have to take perhaps 4 scoops to feel anything, and by then I knew I needed something stronger because you shouldn't ever need 4 scoops of any pre-workout. I haven't used Pulse yet, but just looking at the ingredients, I can tell you it'll be a helluva lot more effective than the basic C4 or C450x (or whatever they call it now).

**Q: Pulse is kind of expensive. Why should I choose it over cheaper alternatives?**
A: Sure, you can find cheaper pre-workouts, but what are you getting for your money, exactly?Go take a look at the supplement fact panels of our competitors and chances are you'll find that they hide everything behind the notorious "proprietary blend," which is merely an indicator that they don't want us to know what we're buying.PULSE's formulation, on the other hand, is 100% transparent. No proprietary blends here, which means you know exactly what you're getting. Each serving delivers nearly 20 grams of active ingredients scientifically proven to improve performance and each bottle contains 21 servings.The bottom line is PULSE just gives you more for your money AND it's naturally sweetened and flavored and has no artificial food dyes or unnecessary fillers.MikeFounder of LEGION

### ⭐⭐⭐⭐ Solid pre-workout
*by C***S on March 22, 2016*

I'm a big fan of Legion products and their overall mission. You can see all the ingredients below, although Mike always does a great job of breaking everything down. So why not a perfect five stars? Well, it's expensive...I know you get what you pay for..but still (especially at only 21 servings). I also wish there was a bigger energy boost. I find it to be a little lacking. Part of that is probably my fault as I should regularly take a break from all stimulants, but I find that hard to do because of the immediate headaches and withdrawal symptoms from caffeine. Overall, you can't go wrong with trying this at least once. 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.
