6g Citrulline, 4g Beta-Alanine, and a smarter 350mg stim system

Norse Fitness Berserkr Frenzy is a strong-stim pre-workout that puts performance first. It starts with solid doses for pumps and endurance, then adds a layered energy and focus system instead of just dumping in a ton of caffeine. Lots of pres give you a buzz, but this one actually helps make your whole workout better. The main players are 6,000mg L-citrulline, 4,000mg beta-alanine, and 2,000mg GlycerSize™ glycerol powder, backed by brain boosters, mushroom support for performance, and caffeine that hits in phases.

That 6g L-citrulline is right in the sweet spot from workout studies. Citrulline beats straight arginine for boosting arginine levels because it skips heavy breakdown in the gut and gets converted in the kidneys. This ramps up nitric oxide, which widens blood vessels for better flow, nutrient delivery, and that full pump you feel in a good session. It also helps clear out ammonia buildup, so you don't get that worn-out, toxic feel in longer workouts.

The 4g beta-alanine is a winner too. Studies back 3.2-6.4g per day, and this tops the usual 3.2g mark. It builds up carnosine in your muscles, which fights off the hydrogen ions that cause burning during intense efforts. This isn't just for show—it helps you push through repeated sets or intervals that last one to ten minutes, like hypertrophy work or compound lifts.

GlycerSize™ at 2g hits the effective range for keeping you hydrated with glycerol. Glycerol pulls in water like an osmolyte—pair it with plenty of fluids, and it helps hold onto that water for fuller muscles and better

Norse Berserkr Frenzy by Norse Fitness contains 120mg Choline (as L-Alpha Glycerylphosphorylcholine), a standard dose for training performance and pump.

Key Highlights

• 6,000mg L-Citrulline — this is a real dose that works, not just something to make the label look good. Citrulline boosts arginine levels better than taking arginine directly, cranking up nitric oxide for wider blood vessels, better flow, and the kind of pump and performance you don't get from skimpy 3g versions.
• 4,000mg Beta-Alanine — that's more than the standard 3.2g from studies on building carnosine. It matters because beta-alanine loads up muscle carnosine over time, which fights the acid buildup that tires you out during those one- to ten-minute bursts of hard work.
• 2,000mg GlycerSize™ — this patented glycerol powder has 65% glycerol. Drink it with enough water, and it helps pull in fluids for hyperhydration and fuller muscles, teaming up with citrulline to boost the pump through volume instead of just nitric oxide.
• 1,000mg L-Tyrosine — a solid amount to support focus under stress in a pre. Tyrosine helps make dopamine, norepinephrine, and epinephrine, keeping your head in the game when training starts wearing on your mental edge.
• 600mg CognatiQ® — a legit addition if you want better mental game, not just a buzz. This whole coffee fruit extract can quickly boost BDNF (brain-derived neurotrophic factor) and sharpen executive function, leading to tighter focus and better workout flow.
• 300mg enXtra® — the exact dose from studies on this non-stim wakefulness booster. Research shows it keeps you alert and attentive for hours without mimicking caffeine, making it a great match for the formula's two-phase stim setup.
• 350mg total caffeine from two forms — 300mg anhydrous for quick energy and 50mg zümXR® for longer release. This gives you a smoother ride than pres that blast you with one big hit and leave you dragging mid-workout.
• 2mg alpha yohimbine from Rauwolfia — a strong stim kicker for folks who want an intense pre. It ramps up that urgent feel and workout drive, but yeah, this isn't for newbies.

Norse Berserkr Frenzy by Norse Fitness contains 120mg Choline (as L-Alpha Glycerylphosphorylcholine), a standard dose for training performance and pump.

Who Is This For?

• Seasoned hypertrophy lifters hitting 60-90 minute sessions who want the whole workout to stay strong. That 6g citrulline, 2g glycerol, and 4g beta-alanine combo boosts pumps, capacity, and fatigue fight for high-volume training.
• Powerbuilders needing hype for heavy sets without losing form on lighter stuff. Fast and extended caffeine drives early intensity, while tyrosine, choline, CognatiQ®, and enXtra® keep your head sharp through accessories.
• Cross-trainers doing intervals, circuits, sleds, and weights together. Beta-alanine shines here—studies show it best for one- to ten-minute efforts where acid buildup limits you.
• Lifters who value mind-muscle link as much as energy. This isn't just caffeine overload; Alpha-GPC choline, CognatiQ®, and tyrosine support focus and drive when training gets grindy.
• Folks who love a visible pump and full muscle feel. Citrulline ramps nitric oxide, GlycerSize™ adds hydration—covering vascular and volume for better pumps.
• People who've moved past basic pres and don't feel 150-200mg caffeine anymore. 350mg total plus alpha yohimbine is for those who know their limits and want more punch.

How to Use

Take Berserkr Frenzy 20-30 minutes pre-workout so caffeine, tyrosine, and nootropics kick in before heavy stuff. Newbies start with 1 scoop to check tolerance—the 350mg caffeine plus 2mg alpha yohimbine can be a lot. Stim pros can try 2 scoops after seeing how 1 feels. Shake well in 12-20 ounces cold water; more water tastes better and fits the 2g GlycerSize™, since glycerol needs fluids to shine. Empty stomach or light meal gives cleanest hit; heavy fatty food can slow it down. Don't casually add energy drinks, burners, or extra caffeine, and watch if you use nicotine too. Team with daily creatine and good hydration for max gains. No cycling needed for pump or endurance parts, but stim breaks help tolerance. Store sealed in cool, dry spot—glycerol can clump if wet.

What to Expect

Minutes 0-10: mixes like your usual pre powder, and on a light stomach, you start feeling more alert soon. Minutes 10-20: fast caffeine kicks in, beta-alanine might tingle, and things feel more urgent. Minutes 20-40: this is prime time—focus sharpens, energy peaks, and citrulline-glycerol pump shows up as you get moving. Minutes 40-90: you should still feel good thanks to zümXR® and enXtra® keeping it steady, not just fast caffeine. Days 1-7: stims, focus, and pump hit strongest while beta-alanine loads. Weeks 2-4: carnosine builds, so hard efforts feel easier to repeat, and you dial in your perfect scoop based on tolerance.
