4 Gauge FAQ's

I hate the taste of pre-workout and protein powders. What does 4 Gauge taste like?

Well, we could say that you’ll love it, but then what would you expect us to say?

But are you sure you really don’t like them? First of all, how long ago was it that you tried a pre-workout powder? Over the past few years, the taste and texture have been greatly improved. The taste isn’t as strong, and it leaves your gag reflex alone.

For many brand names, the days of closing your eyes and chugging it down are long gone.

You owe it to yourself to give 4 Gauge a try. See for yourself how well you may actually like it.

Why just have one flavour?

We like to keep things simple and offer you the best.

We spent months testing flavor combinations. We found that our unique fruit blast flavor was the best tasting by far. It beat many of the leading brands on the market. It tastes so great, which is why we only offer the one flavor.

How long can I feel the effects of the L-Theanine and Caffeine stack?

Results can vary, obviously, but on average this Smart Caffeine can last between 2 - 4 hours.

Try 4 Gauge to see how long it lasts for you. Experiment with it. See if you can go 5 hours.

Then let us know. We want to know your results.

Does 4 Gauge need to be cycled? Or can I use it with every workout?

Good question! For best results, we recommend taking a week off from it every 6-8 weeks. That way it will help to keep your body more sensitive to it.

So this during the time you are giving your body a little bit of a break every couple of months.

How close to working out are you supposed to take 4 Gauge?

This can vary from person to person. Some guys start their workout 15 minutes after taking 4 Gauge, while others wait 30-45 minutes. See how it works for you, and then send us an e-mail letting us know.

an I double scoop it?

Yes. One serving of 4 Gauge is the equivalent of 2 scoops... The real question you should be asking, is 'Can I take 2 servings at the same time?' And the answer is still yes.

We've designed 4 Gauge for those who feel that they want more of the product can safely do so. However we first advise that you try the standard 2 scoop serving and assessing your tolerance, before taking it to the next level.
