If you want to know exactly what you're in for when you take 4 Gauge, this is the section you need to read:

Ricarda, Germany
Age: 27
Goals: Improve Performance

"I was fed up of wasting my money on pre workouts that made me feel jittery or itchy. I’d nearly given up on them altogether. Then I heard about 4 Gauge.What I love about 4 Gauge is that I get a clean surge of energy with a feeling of improved strength and focus too.

I’ve never performed better during my high intensity resistance training. I also now am addicted to the pump feeling it gives me.

Most pre workouts I’ve tried make it so I can’t sleep. But 4 Gauge provides the perfect balance of energy and focus. All this might sound too good to be true…but it’s not.

In terms of the ingredients inside they’re all natural. Which is crazy! Also the taste is great. It’s just got a nice sour edge and mixes well too. If it goes clumpy like all pre workouts do for me, I just use a bit of water and a fork to mix first.

Overall I’d score 4 Gauge full marks. It’s worth every penny to not feel unwanted side effects but still get a ridiculous edge in training! Thanks 4 Gauge!"

Ricky Costa, United States
Age: 43
Goals: Body re-composition

"I’ve worked out for many years and have tried many supplements over the course of those years. In my younger days caffeine never bothered me and taking super caffeinated pre-workout supplements kept me going without problems.

As the years went on life happened and time in the gym became less frequent. Fast forward to 5 months ago and the realization that as you age the loss of muscle mass and energy is a real and sad part of life.

I started going to the gym again and tried many different pre-workout products and find that there are many low quality super caffeinated products out there that have not so pleasant side effects. The one main thing I miss from the old days was a specific product no longer made that helped increase vasodilation for great pumps and I could not find a pre-workout that gave me that until I found 4 Gauge.

The list of quality ingredients shows how superior 4 Gauge is to the competition. The first time taking it brought a smile to my face. This is what I’ve been looking for.

Just enough caffeine to get you going but not feel cracked out, no rapid erratic heart beat, just laser focused on your goal.

The vasodilation is awesome! Great pumps to help get that extra rep and really push through to the next level.

I can feel the difference with 4 Gauge compared to previous products. In the short time I’ve been using 4 Gauge I can see the gains in muscle density and the ability to increase bench weight and reps. My goal is to be bigger and shredded, including 4 Gauge into my diet and workout regiment will help me achieve that goal."

Michelle, United Kingdom
Age: 27
Goals: Tone up and build strength

"I’ve been training for a long time and tried a million supplements for different things. Normally I use pre workouts 3 times per week. This helps me avoid crashes and still get best results from them.

Straight away I was drawn to 4 Gauge, ingredients wise it’s the cleanest pre workout I’ve seen and it’s packaging is certainly striking. No artificial sweeteners and minimal calories. 5 per serving.

What can I say, 4 Gauge blew me away. I felt so energised and powerful, but not shaky and itchy, it made me go a few extra sets in the squat rack that’s for sure!

You feel like you could keep pushing the weights for hours and actually feel the muscle working. It feels incredible! I’ve made some good progress on my physique and for the last few months I’ve only been using 4 Gauge as my pre workout.

It’s helped my with both HIIT training and weight training. And even powered me through a couple of gym classes.

I’m not normally one to write reviews online. But ladies, this pre workout rocks and is now an essential part of my stack."

Aaron Carver, United States
Goals: Smash the Early Morning Workouts

"Hey guys just wanted to drop a line and let you know how much I am enjoying 4 gauge. I took a leap and bought two bottles. This is by far the best and cleanest energy preworkout I have ran across. You can immediately tell this is a quality product.

There are no jitters, no crashes, just a complete uplifting energy that lasts through the most grueling workouts. My performance has improved greatly and I no longer get that sluggish feeling halfway through, I actually want to stay in the gym longer!

Training 6 days per week, usually being up at 5:30am and hitting the gym by 6am, I have zero issues immediately hitting the weights or cardio and being ready to go with 4 gauge. I have been telling as many people about it as possible.

You have a customer for life with this kind of quality product."

John Chow, China
Age: 26
Goals: Muscle Gain

"I’ve always been quite active, playing rugby and football at university. But I wasn’t going to the gym as much I should’ve been.

I started researching online about supplements and read about pre workouts, that’s when I came across 4 Gauge.

4 Gauge really helped get me in the gym when I’d usually be going for a nap in between Uni. I didn’t feel any energy crashes or jitters you might experience with other pre workouts. This was great for me because I had to attend rugby training and lectures at uni after my gym sessions.

Overall I was very impressed with this product. I got healthier and felt better in general after training more. I would recommend this pre workout to anyone who needs that boost to get into the gym."

Take a close look at the core ingredients

L-Citrulline DL Malate (6000 MG)

Extracted from watermelons, Citrulline Malate is arguably the most effective vasodilator on the market.

In plain English: It delivers kick-ass muscle pumps that make your body both look and feel better. Watch your arms and veins pump-up with every rep, and know what it feels like to have your muscles as big and hard as they can possibly get.

Citrulline is converted by your kidneys into L-Arginine, an amino acid that greatly promotes your body's overall levels of nitric oxide – which dilates your blood vessels, letting more blood surge through your muscles.

Not only that, studies have shown 6000mg before exercise has resulted in growth hormone increases of 66.8% after a workout. [1]

In fact, all sources seem to point to 6000mg of Citrulline being the sweet spot to unlock this nutrient's range of benefits - so we packed the full dosage into a serving of 4 Gauge.

[1] Sureda A, Cordova A, Ferrer MD, Perez G, Tur JA, Pons A. L-citrulline-malate influence over branched chain amino acid utilization during exercise. Eur J Appl Physiol. 2010;110:341–351. doi: 10.1007/s00421-010-1509-4


Two nutrients which compliment each other perfectly.

We all know caffeine is an incredible stimulant – but what's L-Theanine? It's an amino acid derived from green tea leaves that delivers focus, calmness and complete control.

The two work together so well that this combination is commonly referred to as 'Smart Caffeine' in the nootropic (brain boosters) community – why? Because the two have an amazing synergy together.

Caffeine's a badass stimulant that raises energy, power output and overall mental awareness – AND L-THEANINE IS THE AMINO ACID THAT KEEPS IT FOCUSED AND IN CHECK.

Raising your brain's levels of GABA – the 'calming' neurotransmitter, L-Theanine steadies all the unwanted extras that comes along with caffeine. You remain calm, and in control while packed full of energy and concentration – and it even makes the effects last longer allowing you to train for far longer. [2]

Imagine caffeine as a high-powered muscle car, L-Theanine puts you firmly behind the wheel with 100% control and confidence.

Great for your body, mood and mindset. Rhodiola Rosea is a Scandinavian herb that is used often by both athletes and academics.

It helps how your body manages resistance – and we're not just talking about weights. Anything tough, be it mental or physical, Rhodiola can helps you build a tolerance to it.

Numerous exhaustive studies have shown the herb to combat both fatigue [3] and depression [4], while boosting cognition [5] and subjective well being. [6].

We chose Rhodiola because it helps eliminate every aspect of a workout that saps motivation, and strengthens that excitement you get when you walk into the gym.

It's the equivalent of training with your favorite workout partner on your best day. You're happy, strong, and are ready for anything the session can throw at you.

Working as a nitric oxide booster and a performance enhancer, Beta Vulgaris is nature's secret weapon for overall physical performance.

Having been used by athletes beetroot has been seen to increase plasma nitrate by 52%, resulting in an improved anaerobic performance of 4.2%! [7]

That's like a running 6-minute mile today, and then running it again in 5:44.88 minutes tomorrow.

Whatever sport you compete in, you know this can be the difference between winning and losing.

Here's why 4 Gauge is the only PreWorkout you'll ever need

You know those days you just start training and have no motivation?

The times when you feel like you're just going through the motions and you're just not feeling it? Physically you felt fine – but your head just wasn't in the game.

We've all been there, sometimes work and life get in the way and you just can't train at the same intensity.

It's perfectly normal ... but it doesn't have to be for you.

To prevent this, we've packed 4 Gauge with high-level cognitive enhancers that contain valuable properties helping to boost both mood and motivation.

This is your 'on' switch to that 'In the Zone' mindset!

All you need are two scoops of 4 Gauge 30 minutes before a workout, and you'll be attacking your session with the power and positivity it deserves.

4 Gauge isn't a short-term win on your everyday workouts – it's a long term solution for tapping into your full potential.

Think about it. If your average performance increases every session – your results will too. They have to.

As you push yourself harder, your muscles are forced to adapt to the new work load and grow to accommodate it.

Here's what this means for you:

  • Hitting the gym? You'll start to lift more.
  • Training for a marathon? This will help you shave minutes off that time.
  • If you're stuck in a rut with your training, and struggling to make progress – this is the answer you've been looking for.
