4 Gauge – Muscle Pumps, Focus, Energy, Stamina – Pre-workout Review

4 Gauge Overview

4 Gauge Shell Package4 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.

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.

And the formula delivers. In a massive way. This is the biggest muscle pump we have ever gotten from a legal supplement, and the surge of energy and power is second to none. It’s topped off with a crystal clear mental focus and great mood enhancing effects.

The vasodilation (pump) effect comes from the huge dose of 6000mg Citrulline Di-Malate combined with natural red beet powder.

The rest comes from the Rhodiola rosea, the theanine-caffeine stack, a real dose of ALCAR and more.

Can’t recommend this enough!! – Love it.

4 Gauge – Advertised Benefits

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.

  1. Explosive Power
  2. Laser Focus
  3. Extended Stamina
  4. 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…


  • L-Citrulline Di-Malate – 6000mg
  • Red Beet Extract – 300mg
  • Rhodiola Rosea – 100mg
  • Caffeine / L-Theanine stack – 150mg / 200mg
  • Acetyl-L-Carnitine (ALCAR) – 500mg
  • Creatine Monohydrate – 1000mg
  • Coconut Water – 300m

4Gauge Model Muscle PumpL-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!!!

Red Beet powder in addition to the citrulline just takes it to another level completely. The natural nitrates in beets are a perfect combination for citrulline because they will act a little slower, prolonging the pump effect.

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.

Theanine-Caffeine in combination with the Rhodiola provides the “laser focus” that was mentioned in the benefits section. Theanine reduces the grubby caffeine feeling and smooths out the energy and mental boost, while releasing calming, mood lifting alpha-waves in the brain.

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.

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.

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.

Side Effects

Doctor Approving ProductThere’s no reports of any negative side effects, and provided you stick to the guidelines on the packaging, theres no reason to expect any.

People who are sensitive to caffeine should take a half dose or something – easy enough to do with powdered mix pre-workouts like this – just to assess how you feel.

There are of course people who should avoid pre-workout supplements: pregnant and breastfeeding women, kids younger than 18 and elderly people.

If you take prescription drugs or have a medical condition we’d advise checking with your doctor before using any workout supplements.

Conclusions and Recommendations

4 Gauge Muscle Pump Review4 Gauge is 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.

There is one flavour of 4 Gauge and it is free of artificial sweeteners, soy, gluten and dairy. It tastes great and mixes really well. If you want loads of sugar and flavours then look at other products, but if you want the massive skin buster pumps then go for this.

4 Gauge can be delivered anywhere in the world, including the UK, USA, Canada, Australia and Europe.
