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.

Frequently Asked Questions

How much caffeine is in Norse Fitness Berserkr Frenzy?

At the full formula profile provided, Berserkr Frenzy contains 300mg caffeine anhydrous plus 50mg zümXR® extended-release caffeine for a total of 350mg caffeine. The anhydrous portion hits faster, while zümXR® is there to stretch the energy curve so the session feels more sustained.

Is the 6g L-citrulline dose actually clinical?

Yes. L-citrulline is most commonly studied in the 6,000-8,000mg range for exercise performance and nitric oxide support, so the 6g dose here lands at the clinical threshold. That is a meaningful difference from formulas using 3-4g, which often underdeliver on pump and blood-flow effects.

Why does Berserkr Frenzy use both regular and extended-release caffeine?

The 300mg caffeine anhydrous provides fast onset and immediate workout urgency, while the 50mg zümXR® extended-release caffeine is designed to keep energy from dropping off too quickly later in the session. This is a more performance-oriented approach than relying on one large dose of fast caffeine alone.

Will this pre-workout make me tingle?

Very likely, especially if you are sensitive to beta-alanine. Berserkr Frenzy includes 4,000mg beta-alanine, which is well within the range known to produce paresthesia, the harmless tingling or prickling sensation many users notice after taking a pre-workout.

Is Berserkr Frenzy good for pump-focused training or is it mostly a stim product?

It is both, but it is stronger than average on the pump side for a high-stim pre. The combination of 6g L-citrulline and 2g GlycerSize™ means the formula supports nitric oxide-driven blood flow and fluid-driven muscle fullness, not just stimulation.

How strong is the focus support in this formula?

Stronger than most basic pre-workouts. You get 1g L-tyrosine, Alpha-GPC-derived choline, 600mg CognatiQ®, and 300mg enXtra®, which creates a more complete concentration stack than formulas that rely on caffeine alone for perceived focus.

Are all ingredients fully disclosed?

Most of the major performance ingredients are clearly disclosed with doses, which is a major positive. The exception is the mushroom complex, where Cordyceps, Reishi, King Trumpet, Shiitake, Lion’s Mane, and Turkey Tail are listed without individual disclosed amounts.

Should beginners use 2 scoops right away?

No. Because this formula combines 350mg total caffeine with alpha yohimbine, new users should start with 1 scoop to evaluate tolerance. Moving straight to the maximum serving is unnecessary unless you already know you handle aggressive stim formulas well.

Can I stack Berserkr Frenzy with creatine?

Yes, and that is one of the best stacks for this formula. Berserkr Frenzy covers pumps, stimulation, and beta-alanine loading, while standalone creatine monohydrate adds phosphocreatine support for ATP regeneration and complements high-intensity performance well.

When should I avoid taking Berserkr Frenzy?

Avoid it late in the day if you are sensitive to sleep disruption, because the formula includes 350mg total caffeine and uses an extended-release form specifically designed to last longer. It should also be avoided if you are stimulant-sensitive, pregnant or nursing, under 18, or dealing with cardiovascular contraindications.

Definitely worth the read!
Format: Kindle
After taking a deep breath and taking in that wicked twist of an ending, I have finally composed myself. My first thought when I started this book was that I love Reyna's character. I was intrigued by her connection with her familiar and the Ruin that is plaguing her land. It came as no surprise that she took her sister's place in an attempt to protect her. When they reach the Air Court everything slows down. This is where it was iffy for me. First of all, I like multiple POV's in books however 7 is a bit much. It starts to interrupt the story line. I felt like I was finally making progress connecting with one character, then it was switched to another person. I felt they all had necessary or pertinent information but not necessarily were they all POV worthy. The only other thing that annoyed me was that Reyna constantly was " trapped." She would rush off without thinking, only to need rescuing. She is brilliant in a fight, but she really doesn't think through anything. Lorcan is amazing. I know he might be on the "bad" list, but his background is so interesting. Eislyn(Reyna's sister) is really so sweet, but calculating. I enjoyed her and Thane's dialogue. The author did an amazing job with the imagery in this book. Everything was so detailed it was easy to fall into the scene. I love unexpected twists and while part of the ending I expected, I wasn't expecting how it took place. All in all, I found it very entertaining and I am very invested in continuing this series. Favorite quotes: "The truth may be twisted but never false." "Who was she if she was not the enemy of the Air Court? What was her purpose of she no longer has that?" "In a war-torn land, love was always a lie."

Great Read!!! Great story!!!
Format: Kindle
The series is long, but Ms. Wolfhart does a fantastic job of weaving this tale while bringing so much to the characters. Surprises and plot twists along the way to keep you intrigued. There is some graphic sex, but is no way the focal point. Grammar was excellent (a rare find with a lot of self publishers) with only a few noted errors. I rarely give 4 stars, let alone 5.

Sadly, DNF
Format: Kindle
I read this thru KU. I LOVED the synopsis. And then I began reading... and it was a DNF at 68% after picking it up and putting it down several times because I really loved the main female character. *****SPOILERS***** Pros: The world is unique, intriguing and fun. The primary female character is bad-a** but not a b*tech or a mary sue. The primary female has depth. I really want to know what happens to her even tho it's been weeks and I don't remember her name. The villains to the point I read are pretty good -- an ever present threat of mysterious and possibly many culprits. Cons: Way, way too many points of view. I stopped counting at 7. It's the prime reason why I don't care about most of the characters or remember their names even when I like them. There's just too many points of view so almost none of the characters have enough book space for the author to properly develop them. This literally killed the book for me. Actually it killed my desire to read. For weeks. The main male is more villain than hero. He agreed to marry the main female then locks her up & eschews her for her sister, all while bad mouthing her as unfit to rule when he never spent any time with her getting to know her. He is actually unfit to rule as he is blind to the woes of his own kingdom and starts off a peace mission to secure a ceasefire through marriage by murdering an inn full of people in her country for no real reason. Plus, he constantly makes promises he does not keep. And it's gross of him to pine for the sister behind the main female's back. ***** As much as I really wanted to see what happened to the main female character, it wasn't enough for me to keep trying to slog thru this book. There was a lot of potential here that just fell short. Hence, 3 stars.

Fae Courts with High Intrigue
Format: Kindle
This book is one that just builds and builds and then surprises you to no end. You may think you know the villains and then you are jolted in another direction. Princess Reyna is a real gem, strong of character, a fierce fighter, and loyal to her family and kingdom. Just when you think she and Lorcan, well you know, the plot is flipped. Can't wait to see where this goes in book two.

Slow, sorry but good
Format: Kindle
This was a slow moving book. Lots of character pov chapters, lots of superfluous descriptions and endless courtly appearances stalled this book to start. Once you get into the heart of the story, it takes off. Before you know it the book is done. My favorite character is Reyna. She is so strong. She is true to herself. She gets into a lot of trouble with her headstrong ways but it's entertaining. I have high hopes for Lorcan. He is honorable to a fault. Thane had turned out to be better than I thought but i still don't like him. Eislin is useless. Great plot twists at the end. I'm looking forward too book 2.
