A clean, effective pre workout.

I’ve been hesitant to take any pre-workout supplements for the past year after doing some research on how sketchy most of the products are (proprietary blends, labels that claim the product has ingredients known to cause cancer, etc.), however after reading about 4 Gauge, I knew that I found the pre workout for me.

The fact that 4 Gauge is completely transparent with their ingredients and processes says a lot about the company as a whole.

About 20 minutes after drinking two scoops, I feel very focused and energized due to the “smart caffeine” blend of caffeine and L-Theanine. On top of the focus, I also feel skin-splitting pumps during every workout.

Overall, this pre workout gets a 5/5, 10/10, 100/100. whatever rating you want to give it. Will definitely buy again.


1 year

I have trained for over 30 yrs covering many sports and im ex military .Getting your nutrition right is the key to making progress in whatever your sport or fitness regime . 4 gauge does what it says on the tin it’s a superb product comes on smooth and gives you a clear focus and pump .

It leaves you very smoothly as well very clever product as are all Roar ambition products .


Excelled in every area of fitness

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.

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 and absolutely smash it.


Clean surge of energy

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.

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.

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!
