How does 4 Gauge work?

How does 4 Gauge work

First of all, there is no magic in this product, rather some well-known traditional herbal knowledge converted into an easy to use powder form.

Basically, 4 Gauge works based on three principles:

  • Vasodilation
  • Enhancing brain signaling for energy outburst
  • Toning the mood

Each of the ingredients are carefully selected in order to complement the above functions which when combined gives a fruitful and productive workout session.

During intense training, muscles are put to stress and would demand energy, nutrients and metabolic factors.

For easy transportation, the blood flow towards those muscles should be proper or in fact enhanced which is achieved by vasodilation.

During vasodilation, the blood vessels enlarge in size allowing more volume of blood to flow through and at the same time, nitric oxide acts on the muscle to relax them thereby channeling the blood flow into specific muscles.

Energy outburst is contributed by GABA enhancers which would ensure more ATP is available at your disposal.

While your body is prepared for a workout, the mind also has to find the synergy with the body, thanks to mood enhancer in the 4 Gauge formulation it is nowhere a concern.

How to use 4 Gauge?

how to use

The manufacturer recommends taking 1 serve (2 scoops) of 4 Gauge powder at least 30 minutes before the workout.

This can be mixed with water or milk or with other supplements; however, it is always best to avoid whey protein mix or mass gainer mix due to cross interaction between ingredients.

In order to boost the performance, even you can double serve it but one serve a day alone would do the best.

The manufacturer recommends cycling the usage in order to juice the best out of 4 Gauge, for which you have to take a week off after 6-7 weeks of straight use.

If you have a personal fitness trainer or a nutritionist, then 4 Gauge has the best potential to be customized as per your body’s requirement.

Some of real-life testimonials and comments are included below help you with decision making.

Ricardo wrote on Nutshell Nutrition that:

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 that I’ve tried and I can’t sleep because of that. 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 as 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!”

Josh wrote on Hypertrophia that:

The powder is easy to mix. There are no lumps and it tastes really good. In my case, I feel the extra energy start kicking in at around the 20-25 minute mark. It keeps me energized throughout my workout too.

It’s a real game changer. My BMI is down and I’m making some very good gains. This stuff really does what it says on the tin. It’s easily the best pre-workout I’ve tried and I’ve tried a lot.
