Each container looks like a shotgun shell, hence the name of the product, but as great as it looks, we were more interested in drinking it and getting to the gym when ours arrived.

4 Gauge Pre Workout Summary – A a definite no-brainer. You will love what it does for you in the gym. For us, pre-workouts that don’t give us the muscle pump are not really that great.
You want the ingredients in the pre-workout to surge through your muscles, that’s mostly the point, and some of them to your brain. By having a wicked vasodilation effect, they can do this – along with all important oxygen of course – and give you a really swole training session.
This is the biggest muscle pump we have ever gotten from a legal supplement

What is 4 Gauge
4 GAUGE has been developed by Roar Ambition as a pre-workout supplement formula for gym goers, weight lifters, bodybuilders, cross-fitters and people into any other form of strength and resistance training.
Each order of 4 Gauge comes packaged in a container designed like a giant shotgun shell. A nice touch for a product which is formulated to help you get an explosive workout. “Load Up Your Guns” is the tagline. Fitting.
Roar Ambition throw down some hefty claims, as is usually made with these products.
The recipe looked great to us even before we placed our order. Delivery was fast, and free for the option we went for. We even got a 3rd tub half price!
We put 4 Gauge in the chamber and gave it a blast (sorry, the puns are strong with this one).

Who Makes 4 Gauge
4 Gauge is a muscle pumping pre-workout drink manufactured by Roar Ambition, a company based in the UK, with international manufacturing facilities.
The company ships 4 Gauge basically anywhere in the world and accept PayPal which made for a fast transaction and shipping time.

Benefits of 4 Gauge
The company describes many benefits of using their supplement. They are generally ways of saying the same thing as every other supplement company, with an emphasis on the following:
- Increased Power and Strength
- Vastly Improved Vasodilation (Muscular “Pump”)
- Sustained Energy During and After Workout
- Low Calorie, Natural Formula (5 calories)
- No Artificial Sweeteners
- Gluten-Free
- Soy and Dairy-Free
How do these claims translate to our actual experience? We’ll get to that, but we should cover the ingredients briefly first.
4 Gauge contains NO artificial sweeteners, and is Gluten Free, Soy Free and Dairy Free.
The number 4 in the product name has more relevance. According to Roar Ambition, the formula has four main effects that help you in the gym.
- Explosive Power
- Laser Focus
- Extended Stamina
- Incredible Muscle Pumps
Everyone loves the pumped up look in the gym but if it doesn’t come with the other benefits then it’s not as useful as it looks.
The ingredients are the key to making this happen. Here’s what’s inside the 4 Gauge formula…
Key Ingredients and What They Do
There are 8 active ingredients in 4 Gauge, and the company have put the inclusion rates right on the packaging. That leaves us with no guesswork, which we love.
Most companies put everything in proprietary blends which we can never fully critique. So….+1 for 4 Gauge so far.
L-Citrulline Malate (6000mg)
Excuse us for saying this but your eyes are NOT deceiving you. That says 6000 mg of Citrulline Malate.
So, that’s interesting on a couple of levels. Citrulline Malate is the Number 1 nitric oxide (NO) booster of all time in our opinion. An NO boost increases muscle vasodilation (they get pumped) and improves overall power output as well as explosive power output during intense physical exercise.
And…it can boost HGH production by over 50% during the workout spike. Not bad.
6000 mg is epic by the way. Scientifically proven. Did we say how much we liked Citrulline Malate?
L-Citrulline Di-Malate at 6 grams is almost unheard of, but it is what the scientific studies that investigated its bodybuilding benefits involved (between 4 and 8 grams is recommended). This is the most powerful thing you can take to get pumped in the gym.
It easily beats arginine, AAKG, nitrosigine, agmatine and any other Nitric oxide boosters because it is so well absorbed. It raises blood arginine levels by more than double what taking arginine itself can do!!!
Rhodiola Rosea (100mg)
If citrulline malate is the King of the Muscle Pump, then Rhodiola is its Queen. Stacks of motivation, a thoroughly positive mental attitude and a cognitive drive is how we’d describe this excellent herb’s effect on us.
You might call it ‘being in the zone’ or ‘feeling dialled in’ to your workout. Whatever you call it, this is what’s doing it for you in 4 Gauge.
Rhodiola Rosea is one of our favourite nootropic / cognitive ingredients of all time. It works so well with the Theanin-Caffeine stack and even reduces the mental and physical stress of an intense workout, improving your mood at the same time as helping you dial in to each lift.
ALCAR (500mg)
Acetyl-L-Carnitine transports fat from cells to the mitochondria (little cellular engines) to be burned as fuel.
It heightens your aerobic output capacity and helps shed some blubber as it does so.
ALCAR at 500mg is a real dose of this aerobic performance enhancer. It can also assist in burning fat and improving energy levels over long workouts.
Red Beet Extract (300mg)
Eating a buck load of beets might get you somewhere close to the extract’s effects but you’d probably end up boffing red crap all over the gym and causing some alarm.
No need when you can have the useful extract and leave the rest for the ponies.
Red beets increase your NO production even more, facilitating mega muscle pumps. This makes you look massive in the gym, and helps you push harder. Each session adds to your overall size on a permanent basis.
The natural nitrates in beets are a perfect combination for citrulline because they will act a little slower, prolonging the pump effect.
Yes, getting swole can contribute to permanent swole…ness!
Creatine Monohydrate (1000mg)
No doubt you’re taking some extra creatine if you are a sensible person and you want the results from the gym. This just keeps you topped up with the most researched and proven ingredient on the planet.
Creatine is a little dose at 1 gram. We’d prefer more, but you can always boost your creatine monohydrate intake by purchasing a tub of it for less than $20 that will last months. You should take 5 to 6 grams per day of creatine in a couple separate doses.
Caffeine and L-Theanine Stack (150mg & 200mg)
On its own, the inclusion of caffeine is a bit meh. So what, right!…everything has caffeine in it.
Combine it with l-theanine, however, and you have an impressive nootropic stack.
Basically, the heightened focus you get from caffeine is amplified by l-theanine. Also, the theanine adds alpha-waves to the mix – the brain signals associated with feelings of well-being.
As a happy side effect, l-theanine takes the edge off the caffeine spike, helping to smooth out the boost it gives and keep it working for longer.
Coconut Water Powder
Electrolytes are essential for us to function, even more so when we are working out. They are the very reason muscles can fire on command…but we lose them when we sweat.
Most pre-workout manufacturers don’t bother putting any in their products, but this is where 4 Gauge has really impressed us and the company has gone the extra mile.
To stay hydrated and able to finish your intense workout, this powder should be in every workout supplement.
Coconut water powder adds the electrolytes that so many pre-workouts don’t include. It’s a thoughtful and key inclusion that shows us Roar know what they are doing.

4 Gauge Customer Reviews
I love this stuff – it is my goto supplement to get me swole.

4 Gauge is the bomb. I have been using it for 6 months now and I feel pumped.
4 Gauge Side Effects and Safety
The effect of vasodilation can be quite pronounced in some people.
During your workout, your muscles may look particularly pumped and the veins on your arms may show more.
People using medication and women who are pregnant/breastfeeding should avoid using supplements of this type.
If you are concerned, consult your doctor before using it.

4 Gauge Summary
4 Gauge is a quality product from a quality company. The ingredients have a great safety record and a LOT of scientific and empirical evidence to support them.

We have used several hundred pre-workout supplements in our time as athletes, trainers and reviewers and very few have given us the ‘pumped’ look and feel together with a mind-blowing positivity that 4 Gauge does.
When we saw the big shotgun shell packaging first, we couldn’t help but think the contents might be a bit gimmicky as well.
How wrong we were. This is a fantastic product and well deserving of the praise it gets.
We absolutely recommend 4 Gauge.
