10g glycerine, 400mg caffeine, and fully open high-stim performance.
Kill It: Stim Crazy Pre-Workout is a high-stim ready-to-drink that's all about hitting hard, staying sharp, and keeping your performance from dropping off during those tough later sets that make or break a good workout. This isn't some basic caffeine drink pretending to be a pre-workout. It packs stimulant power, hydration help, nitric oxide boost, fatigue fighters inside cells, and focus support – all on a fully open label with no hidden blends.
It kicks off with 10g glycerine, which is a big deal in an RTD. Glycerine acts like an osmolyte – that means it pulls water into your tissues, helping with blood volume and making muscles feel full. In the gym, that translates to a better pump, staying hydrated during training, and avoiding that flat, dried-out feel in long sessions. It's backed by sodium and potassium, plus a bit of sodium citrate, tripotassium citrate, and coconut water powder to keep fluids balanced and nerves firing right.
For blood flow, there's 4g L-citrulline plus 750mg inositol-stabilized arginine silicate. Citrulline boosts arginine levels better than taking arginine straight because it skips a lot of breakdown in your gut and liver, then turns into nitric oxide for wider blood vessels. Studies often look at 3-8g a day, with 6g+ being the go-to for pumps, so 4g isn't the max but it's still a solid dose that works. The arginine silicate adds another way to support nitric oxide and even helps with focus, making this smarter than just one pump ingredient.
Beta-alanine is at 3.2g, and that's key because it's the dose studies link to building up carnosine in muscles over time. Carnosine buffers acid during intense efforts, helping delay the burning fatigue that sh
Key Highlights
- 10,000mg glycerine – that's a huge hydration and muscle-filling dose for a ready-to-drink pre-workout. Glycerine works as an osmolyte, pulling fluid into tissues so you get that full, dense muscle feel during lifts instead of the flat buzz you see in a lot of high-stim stuff.
- 4,000mg L-citrulline – a real dose for nitric oxide support that fits right in the 3-8g range from studies. It's not the biggest out there, but it's plenty to help with blood flow, pumps, and getting nutrients to muscles when combined with everything else here.
- 750mg inositol-stabilized arginine silicate – a step up from plain arginine. This stabilized form mixes better and gives another boost to nitric oxide for blood flow and that workout feel, teaming up nicely with citrulline.
- 3,200mg beta-alanine – the solid daily dose that studies show raises carnosine in muscles over time. Beta-alanine only shines when it's dosed right for loading, and this one nails it.
- 2,000mg taurine – a good strong dose for hydration, balancing fluids, and pushing through workouts. Taurine gets tossed in lightly in weak formulas, but here it's high enough to really help with cell hydration and keeping you going.
- 1,000mg betaine – helps as an osmolyte and performance booster, but let's be real with the studies. A lot of them use about 2.5g a day, so this is helpful but not a full standalone betaine hit.
- 400mg total caffeine from three sources – caffeine anhydrous, caffeine citrate, and dicaffeine malate. This setup gives you fast energy plus longer-lasting effects, way better than one type that just spikes and crashes.
- 100mg L-theanine – there to make the stim feel better, not to tone it down. With 400mg caffeine, this dose smooths things out and sharpens focus, but it's still full-on high-stim.
Who Is This For?
- Bodybuilders in high-volume hypertrophy who need pump you can feel and real support to keep going. 10g glycerine, 4g citrulline, 2g taurine, and 750mg arginine silicate team up for full muscles, while 3.2g beta-alanine stops output from dropping late.
- Seasoned pre-workout users who handle high caffeine and want a better RTD than gas station drinks. 400mg from multiple sources plus 100mg theanine gives hard energy with a clean mental edge, not just a mild boost.
- Powerbuilders doing heavy lifts then accessory volume. Stims help attack top sets, beta-alanine, taurine, glycerine, and electrolytes shine when rests get short and fatigue builds.
- Lifters in hot spots or big sweaters who go flat, crampy, or foggy mid-session. Hydration is beefed up with 10g glycerine and sodium/potassium to keep fluids right and training strong.
- Folks who need focus as much as power. Caffeine mix, theanine, and Huperzia serrata extract add a smart brain boost over pure stim formulas that energize but don't lock you in.
- Users who hate hidden blends and want to match doses to studies. Everything's out in the open, so you see what's clinical-strong, what's solid, and what's lighter.
How to Use
Down one full 12 oz container 20-30 minutes pre-training. That lines up the caffeine absorption with citrulline, glycerine, and taurine hitting as your real sets start. If high-stims are new to you, try half first to check tolerance; 400mg caffeine full-on isn't light. It's liquid, so just chill if you want and shake gently if it's been sitting.
For quickest kick, take on an empty stomach or after something light. Heavy fatty food can slow it down. Skip stacking with other stims, fat burners, or extra coffee unless you plan for total caffeine. Standalone creatine pairs awesome since it's not in here – creatine helps quick energy regen while beta-alanine buffers fatigue. If you train every day and want full beta-alanine perks, steady use works, but lots save it for big sessions to keep tolerance in check. Keep unopened ones cool and dry, fridge for cold drinks.
What to Expect
Minutes 0-10: as an RTD, it's easy to drink, and things start quick. You might feel early caffeine vibes and, for a lot of people, beta-alanine tingles kicking in. Minutes 10-20: stims ramp up, mind gets alert, body feels ready to go. Minutes 20-40: peak time for most, with full caffeine effect, sharp focus, and glycerine plus pump stuff building that full muscle feel during lifts. Minutes 40-90: still supported thanks to the multi-caffeine setup, but it depends on your tolerance and food. Days 1-7: energy, pump, and focus hit right away, tingles get familiar. Weeks 2-4: beta-alanine's carnosine build makes hard sets and long efforts easier before burn takes over.

Frequently Asked Questions
How much caffeine is in Kill It: Stim Crazy Pre-Workout?
One full 12 oz container delivers 400mg total caffeine from caffeine anhydrous, caffeine citrate, and dicaffeine malate. That is a high-stim dose intended for experienced users, with the multi-source blend designed to hit relatively quickly and remain noticeable through longer sessions.
Is the 4g L-citrulline dose enough for a real pump?
Yes, 4g is a meaningful and effective citrulline dose, even though it is below the 6g+ amount often highlighted as the classic full clinical benchmark in pre-workouts. In this formula it is also supported by 750mg inositol-stabilized arginine silicate and 10g glycerine, so the total pump experience is stronger than looking at citrulline in isolation would suggest.
Why does this formula use three forms of caffeine?
The formula combines caffeine anhydrous, caffeine citrate, and dicaffeine malate to create a more layered stimulant profile. Anhydrous is the classic fast, strong driver; citrate is highly soluble and can contribute to a quicker feel; dicaffeine malate is often used to help extend the energy curve.
Will Kill It: Stim Crazy make me tingle?
Probably, yes. It contains 3.2g beta-alanine, which commonly causes a harmless tingling sensation called paresthesia, especially in users who take it quickly or on an emptier stomach.
Is this a fully transparent label or a proprietary blend?
It is a fully disclosed formula with no proprietary blends. Every active ingredient and dose is listed, which makes it much easier to evaluate honestly against performance research and category norms.
Does this product contain creatine?
No, there is no creatine in the formula. That is not a downside if you already use a standalone creatine monohydrate, and in many cases it is preferable because you can dose creatine at the full 3-5g daily level without tying it to your stimulant timing.
How does the betaine dose compare to research?
This formula contains 1g betaine, which is useful as an osmolyte and hydration-support ingredient but below the roughly 2.5g daily amount most often studied for exercise performance. In other words, it contributes, but it is not a full clinical standalone betaine dose.
Can I use this for evening workouts?
For most users, no. With 400mg total caffeine and part of that coming from dicaffeine malate, this can stay in your system long enough to disrupt sleep if taken too late, and poor sleep will undermine the recovery you are trying to support.
What should I stack with this formula?
The cleanest stack is a standalone creatine monohydrate taken daily, plus optionally an intra-workout carbohydrate/electrolyte product if your sessions are long or very demanding. Because this formula already covers stimulation, hydration support, and beta-alanine, the biggest missing pillar for many users is creatine.
Is this product beginner friendly?
No, not at the full serving. The 400mg caffeine dose alone makes it more appropriate for advanced pre-workout users, and beginners should either avoid it or start with half a container only after confirming they tolerate stimulants well.
