Pumps, Focus & Clean Energy

Push limits and dominate every session with Kill It Pre-Workout, the foundational pre-training formula from 5% Nutrition. Designed for serious athletes, it combines energy, pump, endurance, and focus in one expertly balanced formula. Best of all: you control the intensity - take 1 scoop for steady performance, or 2 scoops for full-throttle power.

Key Benefits
  • Explosive Pumps & Vascularity: Powered by L-citrulline (2,500/5,000 mg) and other nitric oxide enhancers.
  • Strength & Endurance Support: Includes creatine monohydrate (1,250/2,500 mg) plus taurine, betaine, and glycerol to support cellular hydration and performance under load.
  • Clean Energy & Focus, No Crash: Moderate stimulant dose (~325 mg caffeine in 2-scoop mode) and nootropics to sustain drive and clarity.
  • Flexible Dosing: Start with 1 scoop to test tolerance, then boost to 2 scoops when you need extra intensity.
  • Delicious Flavors & Mixability: Multiple flavor options and smooth blending make it easy to include in your pre-training routine.

INGREDIENT BREAKDOWN

L-Citrulline is a non-essential alpha-amino acid that is converted by the body into l-arginine, which stimulates nitric oxide (NO) production for huge pumps. The key here is that arginine does not absorb as well as citrulline, which bypasses digestion and goes right to the bloodstream. In effect, citrulline does a better job of increasing arginine levels in the blood than arginine itself.(1,2)
Kill It has always contained creatine. That demonstrates the kind of forward-thinking Rich Piana had towards this pre-workout. Too many companies make “creatine-free” pre-workouts when in fact creatine is one of the most effective supplement ingredients on the market. It’s the original cell volumizer, plus it extends endurance and improves strength.(3)
Technically, taurine is a non-proteinogenic amino-sulfonic acid. That simply means it has a different structure than typical amino acids and is not a “building block” of protein. So what does taurine do? It has cognitive benefits and acts as an osmolyte. That means it pulls water into the muscle cells which increases muscle cell volume (water-based pumps). It supports creatine, glycerol, and betaine in this process. (4,5)
Glycerol is a somewhat newer supplement ingredient that has taken the supplement market by storm. That’s for good reason. It’s a powerful osmolyte that hyper-hydrates the muscles and improves exercise endurance. In Kill It Pre-Workout it works synergistically with taurine, creatine, and betaine. Plus, we aren’t using some generic version, we’re using HydroPrime®, a state-of-the-art branded version.(6)
Betaine can be found naturally in beets. It is the amino acid glycine with three methyl groups attached. It’s on the list of newer supplements and has become a standard pre-workout ingredient. Why? Because betaine is an osmolyte. See where we’re going with this formula? Betaine also supports the body's production of creatine, thereby increasing strength and endurance.(7)
Beta-alanine is a non-proteinogenic amino acid that combines with histidine, another amino acid, to form the dipeptide carnosine. By increasing carnosine levels, beta-alanine indirectly promotes training endurance by blocking the buildup of acid in the muscles. However, beta-alanine causes a temporary and harmless tingling and itching sensation. For this reason, we used a smaller but still effective dose. This gives lifters fewer tingles while still extending endurance.(8,9)
This is an amino acid that is involved in the manufacture of the neurotransmitters dopamine and norepinephrine. Dopamine plays a key role in the brain’s reward system, which controls desire, motivation, and cravings. Norepinephrine helps the body and the brain prepare for action, otherwise called the “fight or flight” response. It also supports alertness, attention, and memory.(10,11)
We all know how effective caffeine is, right? Caffeine anhydrous is caffeine with all the moisture removed. This results in a more concentrated caffeine powder. Now Kill It Pre-Workout gets serious with a stronger dose of caffeine (when you use 2 scoops).
Alpha-Glyceryl Phosphoryl Choline is a type of fat that contains high amounts of choline. That's a B vitamin that helps maintain cell membranes. It’s also used to make acetylcholine, commonly called the “learning” neurotransmitter. It has a primary role in regulating brain function and muscle control.(12,13)
Caffeine citrate is a fast-acting form of caffeine. 50% of the total dose is caffeine, for that reason, it’s combined with caffeine anhydrous and brings the total caffeine content to 325 mg for 2 scoops. What if you don’t want that much? Easy - 1 scoop gives you 162.5 mg of caffeine.
This ingredient enhances focus and indirectly increases levels of acetylcholine, which means it works with Alpha GPC to improve cognitive function.(14)
