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

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.

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.
