Kill IT | Kill It | 40 Servings

Kill It (Stim & Pump) is a moderate-stim pre-workout built around a simple idea: enough stimulant to sharpen performance, enough pump support to make training feel productive, and enough hydration and endurance support to keep output from collapsing midway through the session. This is not a maximalist high-stim formula. It is a dual-serving system that lets users scale from 1 scoop to 2 depending on body size, caffeine tolerance, and session demands. At the full 2-scoop serving, the formula delivers 5g L-citrulline, 2.5g creatine monohydrate, 2g taurine, 1g HydroPrime glycerol powder, 2.5g betaine anhydrous, 1.6g beta-alanine, 1g L-tyrosine, 150mg caffeine anhydrous plus 25mg caffeine citrate standardized to 50% caffeine, and 200mcg Huperzia serrata extract standardized to 1% huperzine A.

L-citrulline is the pump centerpiece. Citrulline converts to arginine more efficiently than oral arginine itself, raising nitric oxide production through the arginine-NO pathway and supporting vasodilation, blood flow, and working-muscle delivery. Research commonly uses roughly 3-8g daily, with many performance-focused formulas targeting 6g or more. At 5g in the full serving, Kill It lands just below the classic 6g benchmark but still clearly in an effective range, especially for users who want noticeable pump support without dedicating half the formula to a single ingredient.

The hydration side is well thought out. Taurine at 2g, HydroPrime glycerol powder at 1g, and betaine anhydrous at 2.5g create an osmolyte stack: ingredients that help pull and hold water in and around the muscle cell. That matters for fullness, endurance, thermoregulation, and maintaining output as sets accumulate. HydroPrime is a branded 65% glycerol material used specifically for hyperhydration-style support. Taurine also supports cellular fluid balance, while betaine contributes both osmotic protection and power-output support. This is one of the better aspects of the formula because it gives the pump section more dimension than citrulline alone.

On the performance side, creatine monohydrate at 2.5g and beta-alanine at 1.6g are both exactly half of the classic daily targets often used in the literature: about 3-5g/day for creatine maintenance and 3.2-6.4g/day for beta-alanine loading. That means this product contributes meaningfully, but consistent 2-scoop daily use or additional standalone supplementation is the smarter strategy if you want full saturation effects. Beta-alanine works by increasing intramuscular carnosine, which buffers hydrogen ions and helps delay the burning fatigue associated with hard efforts in the 1-10 minute range. Creatine supports phosphocreatine replenishment and faster ATP regeneration during repeated explosive contractions.

The stim-focus blend is deliberately moderate. Total caffeine is 162.5mg at 2 scoops, combining fast caffeine anhydrous with caffeine citrate for a slightly different release feel. L-tyrosine at 1g supplies catecholamine precursor support, which pairs logically with caffeine for focus under stress. Alpha-GPC 50% at 150mg yields about 75mg actual alpha-GPC, so this is a light supportive dose rather than a fully clinical nootropic dose. The Huperzia serrata extract provides a potent cholinergic accent via huperzine A standardization, making the focus feel more “locked in” despite the modest caffeine.

Transparency is a real strength here. There are no proprietary blends hiding dosages. Every active is disclosed, which lets you judge the formula honestly against research and against your own needs. The honest assessment: the pump-hydration-focus architecture is better than average, while creatine, beta-alanine, and citrulline sit just under the most aggressive fully clinical targets at the 2-scoop serving. Day 1, expect a clean rise in energy, better focus, fuller training muscles, and solid workout composure. Over 2-4 weeks of consistent use, the cumulative gains come mostly from the beta-alanine and creatine contribution, provided you use it regularly enough to build and maintain tissue saturation.
