"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"

4 gauge preworkout women review

Ricarda, Germany


"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."

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.
