Rich Piana’s 5% Nutrition Kill It is a hardcore, pump-and-energy pre-workout, and the 2025 “Reloaded” version cranks it up further: 325 mg of caffeine, a big 5-gram dose of citrulline, plus creatine, betaine, and beta-alanine. It’s a fan favorite. But is it a real performance edge, or just stimulant overload?
Quick verdict: if you handle caffeine well and want strong pumps, big energy, and sharp focus, Kill It delivers and is well-formulated where it counts (that citrulline dose is legit). But it’s a high-stim product, and a few key ingredients are dosed below their research-backed levels. Buy it if you’re a caffeine-tolerant lifter chasing pumps and intensity. Skip it, or start with half a serving, if you’re stim-sensitive, new to training, or already drink a lot of coffee.
A heavily dosed pre workout in classic 5% fashion. Start with a half scoop, and skip it entirely if you are sensitive to stimulants.

Kill It is 5% Nutrition’s flagship pre-workout, built on the brand’s hardcore training ethos. This review covers the current “Reloaded” formula, which bumped up the caffeine and added hydration ingredients over older versions. It’s designed to hit multiple targets at once: pumps, strength, endurance, and energy and focus. It comes as a powder and, more recently, a ready-to-drink bottle.
Bottom line on positioning: this is a high-stimulant, pump-focused pre-workout aimed at experienced lifters, not a gentle “starter” pre.
Ingredients at a Glance
| Ingredient | Dose | Purpose |
|---|---|---|
| L-Citrulline | 5,000 mg | Pumps, blood flow |
| Betaine | 2,500 mg | Strength, power |
| Creatine Monohydrate | 2,500 mg | Strength (partial dose) |
| Beta-Alanine | 1,600 mg | Endurance (partial dose) |
| Taurine | 2,000 mg | Hydration, endurance |
| Caffeine | 325 mg (2 scoops) | Energy, focus |
What’s Good: Pumps, Energy & Focus
Where Kill It shines is the stuff that makes a workout feel great:
- Serious pumps. The 5-gram L-citrulline dose is properly dosed (many pre-workouts skimp here) and drives real blood flow and vascularity. Add taurine and a glycerol ingredient for cell hydration and you get full, pumped muscles that make heavy sets feel better.
- Big, clean energy. The 325 mg caffeine blend (fast and sustained forms) delivers a strong, reliable kick. Great for early mornings, long sessions, or grinding leg days.
- Sharp focus. Added focus ingredients help lock in your mind-muscle connection and drive.
User satisfaction is genuinely high, most people report a great balance of energy, focus, and pumps.
The Caveats: High Stim & Under-Dosed Extras
Now the honest part. A couple of things to know:
- It’s a lot of stimulant. 325 mg of caffeine (roughly three cups of coffee) in a full serving is high. If you’re sensitive, that means jitters, a racing heart, or wrecked sleep.
- Some doses are partial. The creatine (2.5 g) and beta-alanine (1.6 g) are below the usual research doses (5 g and around 3.2 g). They contribute, but they’re not a full daily dose. If you rely on creatine, take it separately too. My Crea-Ten review covers a dedicated creatine option.
And the bigger-picture truth: no pre-workout fixes a bad diet or poor sleep. Kill It is a performance tool that amplifies good training, not a substitute for the basics. If your nutrition and recovery are dialed in, it can give you a real edge on top. If they’re not, fix those first.
How to Use It Safely
Practical guidance:
- Assess your tolerance. Start with 1 scoop (about 160 mg caffeine), not 2. Only move up if you handle it well.
- Timing: mix with water and take it 15 to 30 minutes before training.
- Respect the limits: no more than 2 servings a day, and nothing within 4 hours of bed or you won’t sleep.
- Watch your total caffeine. Don’t stack it with a bunch of coffee, energy drinks, or a fat burner.
Who should avoid it or be cautious: anyone caffeine-sensitive, beginners, people with heart or blood pressure issues, and anyone already high on daily caffeine. If you get palpitations, anxiety, or bad sleep, stop.
Who It’s For
- Buy it if: you’re an experienced, caffeine-tolerant lifter who wants strong pumps, big energy, and focus, and you like a hardcore pre.
- Skip it if: you’re stim-sensitive, new to training, or want a fully-dosed creatine and beta-alanine in your pre (you’ll need to add those anyway).
If everything above lines up with what you are after, here is where to grab it.

Kill It Reloaded is a genuinely strong pre-workout that earns its fan base: proper citrulline for pumps, big energy, and good focus. The trade-offs are the high stimulant load and a few partial doses. For caffeine-tolerant lifters who train hard, it’s a great option, used smartly and on top of solid nutrition. It rounds out the 5% line nicely alongside Real Food for your whole-food meals.
Start low, respect the caffeine, and remember it’s a tool, not magic. I’m not a nutritionist or doctor, so treat this as one lifter’s take and check with a professional if you have any health concerns. Now go move some heavy ass weight. Let’s do this.
