6g Citrulline. 3.2g Beta-Alanine. Your go-to for real workout boosts.

Core Nutritionals Essential Pre-Workout lives up to its name—it's all about the key ingredients that show up in sports nutrition studies, with clear doses and no hidden blends. This isn't a throw-everything-in pre-workout chasing the latest trend. It's a balanced, moderate-stim option that makes your workout feel better: stronger pumps, more sets without fading, sharper focus, and steady performance instead of a big energy spike and crash.

The star is 6,000mg of L-citrulline, right in the sweet spot from research for boosting nitric oxide and workout performance. Citrulline turns into arginine better than taking arginine directly—it skips some breakdown in the gut and gets converted in the kidneys. That ramps up nitric oxide, which widens blood vessels for better flow. You notice fuller muscles, more oxygen to your working areas, and often better reps, especially in tough, high-volume sessions.

Beta-alanine comes in at 3,200mg, the standard daily dose to build up carnosine in your muscles over time. Carnosine helps buffer the acid that builds during intense efforts, so it really helps in those last burning reps where the fatigue usually wins. This isn't a quick-hit ingredient—you load it up over time, and 3.2g is what studies keep pointing to.

Betaine anhydrous at 2,500mg is another solid pick backed by evidence. Betaine acts as an osmolyte, which means it helps cells hold onto water, and it's a methyl donor for important body processes. In folks who train, this dose links to better power, more total work, and

Key Highlights

• 6,000mg L-Citrulline — a full dose that's spot-on from the studies for bumping up arginine and nitric oxide. You get better blood vessel widening, killer pumps, and solid flow to muscles, way better than those skimpy 3g versions.
• 3,200mg Beta-Alanine — the everyday dose that builds carnosine in your muscles. As that ramps up, your muscles handle acid better during tough sets, helping you grind through those final reps.
• 2,500mg Betaine Anhydrous — the dose you see in performance studies. It keeps your cells hydrated and supports metabolism, leading to stronger power and more capacity in trained guys.
• 1,000mg N-Acetyl L-Carnitine HCl — a real amount for brain and performance perks, not just a tiny bit. It helps with energy in your cells and gives a clear-headed vibe for training, better than just more caffeine.
• 300mg Alpha-GPC 50% — here for focus and muscle-brain connection. Since it's 50% pure, you get about 150mg of the active stuff—useful without going overboard, and that's straight-up honest.
• 200mg Caffeine Anhydrous — enough to get you fired up without crossing into heavy-stim land. Makes this pre easy to use every day, unlike those 350mg+ monsters.
• 50mg AstraGin® — the full dose from NuLiv Science, not a weak version. It boosts how your gut absorbs nutrients, which fits perfect in formulas loaded with aminos and performance boosters.
• Electrolytes from magnesium, sodium, and potassium citrates — a smart touch for staying hydrated and keeping muscles firing. Not huge amounts, but they help with contractions, fluids, and pushing through sessions.

Who Is This For?

• Intermediate bodybuilders on hypertrophy plans who dig pumps, tight sessions, and mind-muscle link over wild stims. 6g citrulline and 2.5g betaine boost flow, hydration, and rep quality for volume work.
• Folks training 4-6 days a week needing a usable pre without stim burnout. 200mg caffeine drives you without the overload of 350-450mg stuff.
• After-work trainers wanting support without sleep risks. Moderate caffeine fits later days, while citrulline, betaine, and beta-alanine handle the real work.
• Strength-hypertrophy guys in build phases needing late-session help. 3.2g beta-alanine loads carnosine, key when acid limits sets.
• Athletes who like clear labels to match against studies. Core's all about transparency, so you see every dose plain.
• Gym rats wanting focus without exotic stim overload. ALCAR, Alpha-GPC, and 200mg caffeine give clean intent, not frenzy.

How to Use

Mix 1 scoop in 10-14 ounces of cold water and drink 20-30 minutes pre-training. Matches caffeine's timing to hit before big sets. Shaker's best for mixing. More water tones down flavor and spreads out beta-alanine feel.

Fine on empty stomach for quicker start, but if your gut's touchy, have a light meal and add time. Don't stack with other caffeine unless you're tracking it. Add creatine for energy stores, electrolytes for sweaty days, or intra carbs for long sessions. No need to cycle non-stims, but caffeine breaks can help sensitivity. Keep it sealed, cool, and dry.

What to Expect

Minutes 0-10: not much yet, just settling in, especially with water. Beta-alanine sensitive? You might feel a light tingle starting.

Minutes 10-20: caffeine kicks in, you feel alert and ready. Tingles can pick up, and warm-ups might show early vascular feels.

Minutes 20-40: prime time. Energy's steady, focus is on point, and citrulline pumps shine once you're lifting.

Minutes 40-90: still going strong without a sharp drop. Pump, hydration, and focus hold up in later sets as caffeine eases.

Days 1-7: quick wins from caffeine, citrulline, and focus, while beta-alanine starts loading. Weeks 2-4: carnosine builds, and it feels like a reliable upgrade for tough workouts.
