VMI Sports KXR Pre-Workout Comparisons

VMI Sports KXR PWO Comparison

VMI Sports KXR line-up of pre-workouts offers an option for everyone. When the original KXR was launched the industry was in a stimulant crazy time period. KXR OG High Stim not only had high amounts of stimulants set to rock you for your workout, it also tasted amazing. 

After the success of OG High Stimulant KXR, VMI Sports took their OG High Stimulant pre-workout and made a ready-to-drink version of that for those crunched for time, on-the-go, or who just plain forgot to mix a pre-workout on their way to the gym. 

VMI Sports quickly realized they needed to add options to appease a broader consumer base. VMI Sports needed an option for the value-based shopper and those looking for a fully-loaded pre-workout.

VMI Sports launched KXR Sport with your wallet in-mind. Admittedly this formula was not made for those hardcore gym-goers, but those who just wanted something a little extra to improve their workout and motivate them to get into the gym.

VMI Sports launched a fully loaded pre-workout in KXR Stacked. This was formulated for the serious heath enthusiast. In an effort to not overstimulate the user, VMI Sports focused on other performance areas in their ingredient selection giving users a moderate amount of caffeine but loaded it up with other key ingredients designed for performance, blood flow and focus.

We took the time to look at each one of their four KXR pre-workout options so you can make the best decision when comparing which one is right for you.

VMI Sports KXR Pre-Workout RTD

VMI Sports KXR RTDBorn our of the success of the OG High Stim KXR powder, VMI Sports recognized that they needed an on-the-go, quick option to fill gym coolers across the country for those who prefer the convenience of ready-to-drink or who just forgot to mix their power pre-workout at home. KXR RTD takes a lot of the same ingredients as the KXR OG High Stimulant powder, with just as good as taste, and puts them into an easy to drink 12.5 fl oz drink.

Users will get 6g of a 2:1 ratio Citrulline Malate. This means you get 4g of Citrulline to 2g of Malic Acid. This will aid in improving blood flow and performance. In addition to Citrulline for blood flow, VMI Sports puts 2g of Hydromax Glycerol to aid in the pump.

For performance VMI Sports puts in 3.2g Beta Alanine and 2g Betaine Anhydrous. This will aid in muscular endurance and output. Taurine is added at 1.5g to aid in electrolyte regulation and performance.

KXR RTD also gives users cognitive enhancing ingredients. The formula includes 1.5g Tyrosine and 30mcg of Huperzine-A. These ingredients enhance or elongate your cognitive boos.

As mentioned previously, KXR RTD is a liquid take on their OG high-stimulant KXR pre-workout so it is only fitting that this ready-to-drink product contains stimulants. Users will get a total of 400mg of caffeine from Caffeine Anhydrous, Infinergy Di-Caffeine Malate and Caffeine Citrate. VMI Sports also puts in 1.5mg of Alpha Yohimbine to really boost the stimulants in this formula.

Overall, if you’re looking for a high stimulant pre-workout option that is convenient for on-the-go, or you run into a bind that you don’t have a pre-workout handy, the KXR RTD is a solid choice to grab from your gym cooler.

You can expect to pay anywhere from $3-$5 a bottle depending where and how you buy it.


VMI Sports KXR Sport

VMI Sports KXR SportVMI Sports created KXR- Sport for affordability. This formula is more-so created for those who are price conscious (i.e Walmart shopper) who are not looking for and over-the-top pre-workout formula. For the serious gym rat, this would not be one I would recommend, and if you do have it then I would tell you to take two scoops to ensure you are getting bigger dosages of key ingredients being used.

For blood flow support this formula puts in 1g of Citrulline. At this level of dosage I would not expect a big uptick in blood flow but it can support cardiovascular functions and will be beneficial for endurance based activities.

On the performance aspect users will get 1.6g Beta-Alanine. Beta-Alanine is the ingredient that causes paresthesia or the tingling of the skin. Some people love this while most people do not. At the 1.6g level you should get minor, if any at all, paresthesia. Beta-Alanine should be used daily at 3.2g to reap the full benefits. The purpose of Beta-Alanine is to improve muscular endurance. Taurine is dosed at 1.5g to help regulate electrolytes to ensure you are getting proper muscle contractions. This combined with the 150mg pink Himalayan salt can do that. 

Cognition is addressed with 1g Tyrosine. This non-essential amino acid may help improve focus. 

Lastly, the energy complex is for a broader audience. Users get 200mg of natural caffeine along with 100mg Theobromine. This will give most users adequate energy levels as well as potential to improve focus and blood flow.

VMI Sports KXR Sport retails for just over $1 per serving.


VMI Sports KXR OG High-Stim

VMI Sports KXRThe one that started it all, KXR OG High Stim. KXR was launched during a boom in the love of stimulants. At that time brands kept pushing the levels of stimulants, and KXR became one of the very first pre-workouts to contain a 400mg level of total caffeine. Also during that time flavors were mid but KXR set the new standard for flavoring in a performance powder. 

If you’re stimulant sensitive I would not recommend this pre-workout. It is only fitting we start with the stimulant portion of this formula. Users will get 400mg of total caffeine from Caffeine Citrate, Caffeine Anhydrous and Di-Caffeine Malate. The multiple sources of caffeine provides a euphoric experience with long-lasting energy levels. VMI Sports also adds 1.5mg of Alpha Yohimbe which can provide a large energy boost via engaging the central nervous system. Theobromine is also included at 300mg.

KXR does contain more than just stimulants. KXR is the only pre-workout in the series to contain elevATP at 150mg. elevATP helps your body increase ATP production, which is the source of fuel that we use during our workouts. Other performance boosting ingredients include Beta-Alanine at 3.2g and Taurine at 1.5g.

For blood flow, KXR provides 6g Citrulline Malate at a 2:1 ratio. 

Combining stimulants with cognitive enhancing ingredients has a synergistic effect. VMI Sports KXR OG High-Stim includes several cognitive boosting ingredients. Users will get 500mg VitaCholine, a branded version of Choline Bitartrate. In addition VMI adds 30mcg of Huperzine-A which allows the VitaCholine to work for a longer period of time. Lastly the formula includes DMAE at 300mg which also boosts focus and concentration.

KXR OG High-Stim is for those who want a boost of stimulants with improved cognition in a great tasting flavor.

KXR OG High-Stim is over $1 per serving, just slightly higher than KXR Sport.


VMI Sports KXR Stacked

VMI Sports KXR StackedVMI Sports KXR Stacked is their loaded pre-workout formulated for those serious about their gym sessions. It will be the most “costly” pre-workout in the VMI Sports line-up, but it’s justified by the formula.

The formula starts with 6g of MAXed L-Citrulline Malate at a 2:1 ratio. This will improve nitric oxide production and blood flow. 

The formula also addresses cognition with the inclusion of several focus boosting ingredients. Users will get 500mg VitaCholine combined with 30mcg of Huperzine A to extend the benefits of Choline Bitartrate. DMAE is also included at 300mg and Tyrosine at 1g to boost cognition. 

For performance benefits users will get 3.2g Beta-Alanine, the acceptable dosage of Beta-Alanine for improved muscular performance. Taurine is used at 1.5g combined with 384mg Pink Himalayan Salt to boost muscular hydration and contraction. Betaine Anhydrous is dosed at 1,250mg for strength and power output. 

VMI Sports KXR Stacked does not rely on a high stimulant formula. Users will get 200mg caffeine from a blend of Caffeine Citrate, Caffeine Anhydrous and Infinergy Di-Caffeine Malate. This is an adequate amount of caffeine with multiple sources to give you a long lasting energy effect without a crash, while not suppressing blood flow.

This is the most well-rounded pre-workout in the KXR series that retails for just under $2 a serving. 

Final Takeaway on VMI Sports KXR Pre-Work Options

At the end of the day you need to choose which pre-workout is right for you based on value, benefits sought, availability and flavor. For me, an avid gym-goer, I would elect KXR Stacked the majority of the time and KXR OG High Stim when I need a kick in the ass (KXR RTD is a good option too). If I was just going to do cardio or an endurance activity I would elect to go with KXR Sport. If you're new to the gym, KXR Sport would be a good starting place and then you can assess your reaction after use.
