So, what effects can you expect when you use 4 Gauge?

Increased Focus

The more focused you are, the better your workout will be. 4 Gauge helps keep your head in the game.

More Determination

After a shot of 4 Gauge, you’ll want to push yourself to the limit, cranking out more reps than usual.

Less Fatigue

With 4 Gauge, you’ll be able to train longer and harder than ever before.

Better Pumps

Flood your muscles with blood, amino acids, and oxygen for better pumps, increased strength, and faster recovery.

Increased Strength and Power

Fire up your muscles and nervous system to achieve new, higher performance levels. Unlike almost every other pre-workout supplement, 4 Gauge won’t cause a massive energy crash as it begins to wear off.

Because of the ingredient L-theanine, your energy levels will decrease gradually over several hours, so you’ll be able to leave the gym and get on with the rest of the day instead of needing a nap!

How and When to Use it?

4 Gauge is very easy to use. Just mix one scoop (supplied) with 12-16 ounces of water and drink it 15-30 minutes before you’re due to start your workout. This stuff kicks in fast, so it’s best to use it only a short time before you’re going to exercise.

But, because of its long-lasting effect, it’s okay if you need to delay the start of your workout. 4 Gauge will keep on working.

Possible Side Effects

Made from tried, tested, and 100% natural ingredients, the chances of unwanted side effects with 4 Gauge are quite slim. But, if you are very sensitive to the effects of caffeine, you may feel like you’ve had one coffee too many after using this product.

Some users also report that they experience skin tingling with 4 Gauge. That’s one of the effects of L-citrulline, the vasodilator.

These side effects are nothing to worry about and will decrease with repeated use. If they bother you enough, just use a half-sized dose of 4 Gauge, and increase gradually after a few weeks, once you have become accustomed to the ingredients.

Safe For Women?

While 4 Gauge is undoubtedly marketed toward men – it comes in a bottle that looks like a shotgun cartridge, after all – it’s safe for women to use too. However, because of the high caffeine content, it is not recommended for use during pregnancy or while breastfeeding.
