Finaflex | WRN Pre | 20 Servings

Finaflex WRN Pre is a fully disclosed, high-stimulant pre-workout built around a simple but effective philosophy: hit the major performance pathways hard enough to matter. Instead of hiding behind a proprietary blend, it gives you clinically relevant doses across pump, strength, endurance, focus, and acute stimulation. This is not a beginner “energy drink in powder form.” It is a serious training formula that combines foundational ergogenics with aggressive central stimulation and nootropic support.

The foundation starts with 6,000mg of L-Citrulline Malate 2:1, a clinical lower-bound dose for meaningful nitric oxide support. Citrulline is converted to arginine in the kidneys more reliably than oral arginine itself, increasing nitric oxide production and driving vasodilation, blood flow, and working-muscle nutrient delivery. In practical terms, that means fuller pumps, better muscle oxygenation, and less of the flat feeling that shows up deep into a session. The 5,000mg of micronized creatine monohydrate is the gold-standard daily dose for phosphocreatine replenishment, strength output, repeated-bout power, and long-term lean mass support. Micronization doesn’t change the molecule’s proven performance value, but it does improve mixability and mouthfeel.

Beta-alanine lands exactly where it should at 3,200mg—the clinically validated threshold used across the literature. Beta-alanine is the rate-limiting precursor to carnosine, the intracellular buffer that helps soak up hydrogen ions during hard training. Research is especially strong for efforts lasting roughly one to ten minutes, which maps directly onto hypertrophy work, repeated hard sets, and high-intensity conditioning. You may feel the classic tingling paresthesia acutely, but the real payoff comes with consistent daily use as muscle carnosine stores rise over weeks.

WRN Pre doubles down on power output with 2,000mg betaine anhydrous plus 1,000mg of NO3-T® betaine nitrate. Betaine supports cellular hydration, methyl donation, and performance output, while the nitrate component adds a second nitric oxide pathway beyond citrulline. That matters because citrulline and nitrates do not rely on the exact same route to increase NO signaling, so you get a more layered pump-and-performance effect than from citrulline alone.

The focus and performance support side is unusually strong. Alpha-GPC at 800mg is above the commonly studied 300–600mg range, supplying a robust amount of choline for acetylcholine synthesis. Acetylcholine drives both cognitive sharpness and neuromuscular signaling, so this dose is positioned to support stronger mind-muscle connection and more deliberate training intensity. It is paired logically with Huperzia serrata extract, included for huperzine A activity, which helps slow acetylcholine breakdown. Peak ATP® at 450mg is also a standout inclusion. This patented ATP ingredient has human data supporting power output, blood flow, and training performance, and 400mg+ is exactly where it becomes interesting.

Then there is the stim profile: 400mg caffeine anhydrous, 100mg theobromine, plus an advanced stimulant/thermogenic component from the bark extract. Caffeine drives alertness, reaction time, perceived energy, and reduced effort perception. Theobromine is a milder methylxanthine with longer, smoother activity, adding bronchodilation and mild vasodilation rather than just a sharper edge. GABA at 400mg is unconventional in a pre-workout, but the likely intent is to smooth the stimulatory experience and reduce the “wired but scattered” feeling some high-stim formulas produce.

As a system, this formula makes sense: citrulline plus nitrates for blood flow, creatine plus Peak ATP® plus betaine for output, beta-alanine for fatigue resistance, Alpha-GPC plus huperzine plus caffeine for focus, and theobromine/GABA to shape the feel of the energy curve. Transparency is a major win here—every active and dose is disclosed, which immediately puts WRN Pre ahead of the many high-stim pre-workouts that hide behind blends. On day one, expect strong energy, pronounced tingles, elevated focus, and a serious pump. By weeks two to four, creatine saturation and rising carnosine stores make the formula feel even better, with more repeat power, better work capacity, and less drop-off late in training.
