Ketone-fueled pre-workout with light caffeine and solid mineral backup

VMI Sports KXR Pre-workout is a low-stim option that puts ketones front and center, totally different from most pre-workouts. It skips the huge caffeine loads, massive pump ingredients, or everything-but-the-kitchen-sink blends. Instead, it packs 7.2 grams of goBHB® beta-hydroxybutyrate salts—BHB is a ketone your body can use for fuel—plus solid magnesium and just 100mg caffeine from Robusta coffee. You get smooth energy for training, electrolyte support, and steady focus without a big stim kick.

The core is the goBHB® mix: 2.4g calcium beta-hydroxybutyrate, 2.4g sodium beta-hydroxybutyrate, and 2.4g magnesium beta-hydroxybutyrate. BHB is the main ketone that floats around in your blood for energy, super handy if you're low on carbs or training fasted. In real life, it means even energy without needing tons of stims to get going. goBHB® is branded from Compound Solutions, so it's a quality ketone source, not some cheap knockoff.

Magnesium stands out too. You get 295mg total from magnesium beta-hydroxybutyrate and TRAACS® magnesium bisglycinate chelate—that's close to the 310-420mg daily range you see in studies. It's a good chunk for a pre-workout. Magnesium helps over 300 enzyme reactions, keeps ATP stable—that's your cell's energy currency—supports nerves and muscles, and is key for making energy. They use Albion’s TRAACS® chelated form, which is easier on your stomach and absorbs better than rougher types.

Chromium is in at 200mcg as TRAACS® chromium nicotinate glycinate chelate, right at the low end of the 200-1000mcg studied range. Chromium boosts insulin signals through something called chromodulin, helping with

VMI KXR Pre-Workout by VMI Sports contains 35mg Niacin (Vitamin B3), a standard dose for training performance and pump.

Key Highlights

  • 7,200mg goBHB® ketone salts—this is what makes the formula stand out, split as calcium, sodium, and magnesium beta-hydroxybutyrate. It skips heavy stims and uses ketones for steadier energy, killer for fasted or low-carb days.
  • 100mg caffeine from Robusta coffee—that's low for a pre-workout. Studies show caffeine works best at 200-400mg or 3-6 mg/kg, so this isn't maxed out; it's a chill dose for smooth alertness you can handle every day.
  • 295mg magnesium total—a solid amount that's almost at the 310-420mg daily range from studies. Magnesium keeps ATP steady and helps nerves and muscles work right, making it a key player for performance here.
  • TRAACS® magnesium bisglycinate chelate—Albion’s chelated version is a smart upgrade over basic minerals. Chelation means better absorption and less stomach issues, great for something you use often.
  • 200mcg chromium as TRAACS® chromium nicotinate glycinate chelate—hits the start of the researched range. Chromium helps with insulin and glucose control, which fits nice with the ketone energy angle.
  • Fully open label—every ingredient and dose is right there. In a world of hidden blends, this lets you check it against real research yourself.
  • 300mg L-Tyrosine—not a huge dose for stress and performance, but it helps in this low-stim setup. Tyrosine builds dopamine and norepinephrine, so it boosts focus with the caffeine.
  • 50mg Alpha-GPC—below the usual doses for power or brain boosts, so we're real about it. It still fits the focus vibe, but ketones, minerals, and light stims are the stars.

Who Is This For?

  • Low-carb and keto folks wanting a pre that matches their diet, not fights it. 7.2g goBHB® ketones give a unique energy feel, with minerals boosting readiness.
  • Early morning lifters avoiding 300-400mg caffeine before the day. 100mg gets you alert, while magnesium and BHB make it feel more complete than coffee.
  • Intermediate gym users after a clear-label, easy pre for daily use. No hidden blends, just open doses with light stims you can hit repeat on.
  • Athletes who hate harsh stims but want real pre support. Low caffeine leans on goBHB®, magnesium, and light nootropics from L-Tyrosine and Alpha-GPC for smoothness.
  • Fasted trainers who start sessions feeling off. Ketones plus sodium, calcium, magnesium help you feel geared up without a big meal.
  • Busy pros hitting the gym after tough days, needing calm over hype. Caffeine and tyrosine support focus under pressure, without jitters for evenings.

How to Use

Mix 1 scoop with 10-14 ounces cold water and down it 20-30 minutes pre-train. That's the spot for caffeine and focus to kick before warm-ups turn serious. If you're super sensitive to stims, try half a scoop first—even though it's low by pre standards. Shaker's best 'cause ketone salts mix better with shaking. Empty stomach speeds it up, popular for fasted folks, but light food's okay if your gut's picky. Don't stack with other caffeine bombs unless you're aiming higher and know your limits. Goes well with plain creatine, intra hydration, or a separate pump if you need more nitric oxide. No need to cycle the formula, but ease off caffeine sometimes if you're a regular pre user—tolerance builds. Keep it sealed, cool, and dry; mineral powders clump easy if wet.

What to Expect

Minutes 0-10: you sip it and it feels lighter than heavy pres—no big stim punch coming. Minutes 10-20: 100mg caffeine eases in with clean alertness, not shakes, as ketones and minerals build that 'ready' vibe. Minutes 20-40: prime time—focus up, energy steady, workout flows without overload. Minutes 40-90: smoother ride than high-stims, no huge drop 'cause you're not peaking hard. Days 1-7: you notice the easy energy and consistency right away, not big changes over time. Weeks 2-4: shines in routine use, especially swapping from rough pres that mess with sleep or tolerance.

Key Ingredients

  • Caffeine from Robusta Coffee — Light stimulant lift without high-stim fallout
  • Niacin — Small B-vitamin inclusion tied to chromium complex

Frequently Asked Questions

How much caffeine is in VMI Sports KXR Pre-workout?

Each 1-scoop serving provides 100mg caffeine from Robusta coffee. That is low by pre-workout standards, where many formulas land between 250mg and 400mg, so KXR is designed for smoother energy rather than a massive stimulant hit.

What makes this formula different from a typical pre-workout?

The biggest difference is the 7.2g goBHB® ketone salt complex. Most pre-workouts build around caffeine, citrulline, and beta-alanine; KXR instead leans on exogenous ketones, minerals, and light stimulation for a steadier training experience.

Is KXR Pre-workout good for keto or low-carb training?

Yes, that is one of the clearest use cases for this formula. The goBHB® complex supplies beta-hydroxybutyrate directly, which makes more sense for low-carb, ketogenic, or fasted users than a standard stim-only pre-workout.

Does KXR have a fully transparent label?

Yes. There are no proprietary blends in the verified formula, so every active ingredient and dose is listed openly on the label.

Will this give me a big pump?

Not in the way a citrulline- or nitrate-based pump formula would. KXR is not built around nitric oxide ingredients, so its strengths are smoother energy, mineral support, and ketone-based fueling rather than maximal vascularity.

Is the L-Tyrosine dose clinically strong?

No, not by published stress-performance standards. Research on L-Tyrosine is typically much higher, around 100-150mg per kilogram of bodyweight, so 300mg is best viewed as a supportive addition rather than a headline nootropic dose.

What do the TRAACS® minerals do in this formula?

TRAACS® is Albion’s chelated mineral technology. In KXR, the magnesium and chromium chelates improve the quality of the mineral portion of the formula, supporting absorption and tolerability compared with cheaper generic forms.

Can I stack KXR with creatine?

Yes, and that is one of the smartest ways to upgrade the formula. KXR does not provide creatine, so adding 3-5g of creatine monohydrate daily gives you direct phosphocreatine support for strength and repeated high-intensity output.

Can I use this in the evening?

For many users, yes, because 100mg caffeine is modest. That said, if you are highly caffeine-sensitive or train close to bedtime, even this dose can still affect sleep.

Is Alpha-GPC meaningfully dosed here?

It is included at 50mg, which is below the amounts commonly used for acute cognitive or power-output effects. It fits the focus theme of the formula, but it is not one of the primary performance drivers.

New Online Access Security Features Actually Compromise Security
Style: Prime Visa
While I started out very satisfied with my Amazon Prime Visa, I have since become discouraged and frustrated. When I first started using my card, I was accumulating my reward points on a regular basis and they were representative of the purchases I made, both on Amazon and through other vendors. But over the last couple years, I noticed I wasn't earning as many points as I had before and especially for Amazon purchases. There were discrepancies in the points I expected to earn and what were actually awarded. The few times I called to inquire about this it was a hassle to get through to a live customer service representative. I seldom used the card anywhere but on Amazon and truth be told, I expected to earn more using the card on Amazon than I actually did. But the most important reason my opinion of this card has changed for the negative is because of recently implemented security procedures for accessing my account online. I have had my card for well over 10 years and never had an issue signing into my account. Like most online accounts, an extra security layer was added where after logging in, a security code was emailed or sent to my phone to let me complete the log in process. But starting last year, logging into my account became not only a hassle but ironically more of a security concern than what the process was designed to protect. I would use my password, enter the security code that was emailed or texted to me, but then see a screen telling me that "more information was needed" and to call an 800 number to speak with a customer representative. I would call the 800 number only to have a voice prompt ask me to then enter my card number, my zip code, my date of birth and MY SOCIAL SECURITY NUMBER! Only then was I connected to a live person who would then give me yet another security number to be entered online and then I could finally access my account. The first time it happened, I called customer service and asked what this was about. I was told it was just a "random" check that is done to verify my identity. I was assured it didn't happen regularly and that gone through the process once, it shouldn't happen again. But the next time I logged in it did. I called customer service again but this time I was told it was because I had selected there to be this secondary security check myself. I explained that I had done no such thing. The customer service rep claimed to check my account on their end and said yes, it appeared my account indeed had a secondary security check option selected. I asked if it could be removed explaining that I was very uncomfortable providing all that additional information through a voice prompt system. The customer service presentative told me that she was able to remove the secondary security check and that the next time I logged in there shouldn't be any issue. But the 3rd time I attempted to log in I had to yet again go through this secondary security check. Once again I called customer service. This time I was told that there must be some type of glitch in my online account and I was transferred to the technical support department. The support tech claimed that there was this "secondary security" layer enabled on my account but assured me he was able to remove it on his end. He also assured me that the issue was finally corrected and I should be able to log in going forward without this extra security hassle. Yet again the next time I logged in I was still being asked to call the 800 number and provide all that information through the voice prompt system, including my social security number. At that point I asked to be transferred to a technical support securitiy manager. After giving me all the same previously provided explanations and claiming to have fixed the issue (he didn't) and almost an hour of my time, he finally explained that the problem was on MY end. This extra security layer was NOT implemented by Amazon or Visa. Instead, it was implemented by their 3rd-party vendor that actually administers online accounts and processes online payments. It turns out that while it was intended to be a one-time verification, any deletion of cookies and cache from my computer would reset my account as needing this secondary verification. My response was that I regularly delete cookies and my cache as a security measure. The tech said that if I want to avoid this secondary verification, I should stop deleting cookies and cache, PLUS disable auto-deletion in my browser. I explained that while disabling auto-deletion on my browser could solve the issue, it would disable auto-deletion for all my browsing history and that's a security issue. Moreover, if I chose not to disable auto-deletion then every single time I wanted to access my online account I would be required to enter personally identifiable information (my social security number) which is also a security risk. The tech reluctantly agreed but said that their customer service had no control over this because it was added by that 3rd party account/payment processing vendor. All this being said, I stopped using my Amazon Visa card. I opened a new credit card through my bank that was offering a $300 cash-back bonus for spending $600 over the first 3 months. I'm able to log into that online account using my login, password and the verification number that was simply sent to me via email or text. I don't need to provide all the personal information for a secondary security verification through a voice-prompt system and I'm still able to clear my cookies and cache on a regular basis. This experience was frustrating for several reasons. First and foremost, I was never told about this secondary security layer that had been added for online access despite being a cardholder for over 10 years. Second, when I attempted to inquire why there was a secondary security layer, I spoke with 3 different customer reps who each gave me a different and erroneous explanation for why the secondary security layer was there in the first place. Third, each of those customer service reps assured me the issue was corrected only for that to not be true. And finally, the secondary security layer provided no real extra security without potentially compromising the health and security of the device that I was using to access my account. In the end, there's more than enough security issues to watch for when using online devices and accessing sensitive account information. Safety is important but so is ease-of-use. The Amazon Prime Visa card has become more of a liability to use for both safety and convenience than the purported benefits that the card offers. Moreover, it is completely unacceptable that 3 customer service reps gave me 3 different and erroneous explanations for what I was experiencing and it is egregious that none of those explanations were even correct. In the end, it's my opinion that there are better cards with better rewards that employ more informed customer service reps with online access security features.

TireJECT cannot work miracles
Size: Compact Car, Mid-size Sedan, Size: Compact Car, Mid-size Sedan
TireJECT is a surprisingly thin fluid that supposedly contains fibers that must help stop up holes. Frankly I'm still confused as to how this stuff can plug a leak, but apparently it does. Tons of reviews say so. I say apparently because the product did not completely stop a slow leak in my tire, but that's OK. I knew it likely wouldn't. I'll have to replace the tire unfortunately. I had a garage install four nearly-new tires on my car. After installing, a heavy leak was discovered in one of them. They took the tire off again and found a small tear near the rim/bead of the sidewall. Since the tear would be flat against the rim, they suggested to let them try and repair it with tire patch adhesive and lots of bead sealer. They were confident, so I went for it. It seemed to work, but it went flat a few days later. TireJECT seemed like the perfect solution to the slow leak since I wouldn't have to disturb the repair. I bought the kind without the syringe and regretted it immediately upon trying to use it. First, the valve stem removal tool broke as it loosened it. I had to buy a new tool down the road. When I went to inject, I squeezed as hard as I could but it just wouldn't flow past the TPM. It also kept leaking out of the flex joint of the nozzle. I had a huge syringe on hand, so I sucked up the rest from the bag, ziptied the hose on both ends and got the rest of the product into the tire. HURRAY! The tire pressure had fallen considerably by the next morning. BOOOoo. I contacted TireJECT, and after several emails (and long waits in between). They determined their product was not suitable for my use case. They refunded what I paid without me even asking. I really appreciated that. That said, before injecting, the tire would go flat overnight. So, TireJECT does work to a good degree. I'm half tempted to overdose the tire with another package. Give TireJECT a try! Though, be sure your situation matches their criteria. If you have a TPM, opt for the package that comes with a syringe. You will need it. Also, throw the cast pot metal, tire stem tool out and get a decent machined one before you do the repair. Thank me later.

Works once again!
Size: Compact Car, Mid-size Sedan
Third time using TireJect on a vehicle, and it's worked perfectly each time. First was the off-road formula for leaking motorcycle tire beads.... then this formula my light SUV with a slow leak until I could get the tire replaced. This was for a stubborn tire that had a leak SOMEWHERE, and usually would lose 10-15 psi overnight after a fill-up. Two days later, still fully inflated and no signs of trouble. This is great because this formulation is also okay for tire pressure sensors. Will continue to purchase this product for similar issues going forward. High quality, durability, and easy to use.

Works like a champ!
Size: Full-size Truck, SUV
It works great! I had one fairly slow leak and 2 very slow leaks. 3 Tires. 2 were on my 94 Ford Ranger. I put a little more than 1/2 the packet in my fastest leaking tire (on the Ranger) and about 1/4 of the packet in the 2nd tire of the same vehicle. Lastly, I put the final 1/4 in a very slow leaking tire on my 2000 Ford F-150. All tires have stopped leaking!! I am delighted with the effectiveness of this product!!

Seems to have done a great job.
Size: Full-size Truck, SUV (2-pack)
One of our cars has suffered from rim leaks and was driving me nuts. Constantly being asked by my wife to top off the tires on her car. When I replaced a damaged rim I asked the tire shop to look for the source of the leaks. They said the "alloy" rims had started to corrode and did their best to get them to seal but warned me they would likely leak again. This spring when I removed her snow tires I found 3 of her 4 tires had gone completely flat in storage. The fourth was the new rim which was fine. I considered buying new rims that won't have this problem but wanted to wait until her times need to be replaced. The batteries in the TPMS sensors are getting very low so likely these will need to be replaced as well. I thought to try some sort of sealant. Most of the products I saw were not rated for automotive systems and offered warnings about risk to the TMPS sensors. This seemed to be the only product rated for my application and claimed it would not harm our car's sensors. So I gave it a shot. I ordered the SUV package that came with an injector and two 8-oz bottles. I put 4 oz in each tire per the instructions. Overall the process was easy except the valve core extractor broken on one of the tires. I had to pick up a replacement at a local auto parts store. Also, injecting the sealant creates a small amount of pressure in the tire that, if one doesn't release by drawing out the plunger, will burp a small amount of sealant onto the rims. Fairly easy to clean up with WARM water and easier to avoid after the first experience. Drove the car around at a variety of speeds for 10-15 minutes (had errands to run) and waited to see what happened. Great results. Weeks later and the tires still have the correct pressure. I am not sure how long this will last but hopefully for the remaining life of the tires at least. I took one star off for easy of use / easy to install because the valve core extractor is made of extremely cheap aluminum and I am sure others will have a poor experience with it. Be forewarned and consider buying one before you start jacking up your car and letting the air out of the tires only to find you break the tool on a sticky valve core and are unable to complete the job without a trip to the auto parts store. I'll update this review in about a year to report on the long-term outlook for this product.
