The Reported Benefits of 4 Gauge

  • Elevates nitric oxide levels
  • Spikes energy levels
  • Helps increase strength and endurance
  • Encourages muscle growth and speedy recovery
  • Promotes effective delivery of nutrients to the muscles

How Does 4 Gauge Work?

4 Gauge works through the use of nitric oxide boosters, stimulants, and branched chain amino acids (BCAAs). These nutrients all of have different functions, but they work together in a synergistic way to produce results.

The nitric oxide boosters dilate your blood vessels and improve your blood flow, which leads to a better pump and more oxygen in your muscles. Oxygen is the power source behind your lifts, which means that more oxygen means more power. Nitric oxide boosters are important because having more muscular power allows you to lift more weight and therefore build muscle at a faster rate.

Stimulants are key because they spike your energy levels, which ultimately contributes to better performance in the gym. Higher energy levels lead to better motivation and endurance. You become more into your workouts and are also able to workout for much longer periods of time with the use of stimulants. Every pre workout supplement should include at least one stimulant.

BCAAs are a vital part of any pre workout supplement because they have been clinically proven to promote growth and recovery. Using BCAAs before your workout helps increase the concentration of certain strength boosters in your muscles and puts your body in a better position to build muscle.

4 Gauge Ingredients

Citrulline Malate: The Key NO Booster

Citrulline is the primary nitric oxide booster in this formula. Usually, the key NO booster is either Arginine or Citrulline. They both are excellent, but we actually like pre workout supplements that include citrulline because certain studies have shown that when it comes to building muscle, Citrulline can actually be up to twice as effective as Arginine.

Creatine Monohydrate: More Weight, More Reps

Creatine monohydrate is perhaps the most clinically studied ingredient in all of sports nutrition. Countless clinical studies have shown that creatine monohydrate when taken as a pre workout supplement significantly improves strength.

Athletes who use creatine monohydrate experience near immediate increases in the amount of weight they are able to lift, which is why it is best taken as a pre workout supplement rather than post workout. You want to make the creatine available to your muscles during your workout instead of after your workout.

L-Carnitine: The Fat Loss BCAA

L-Carnitine is one of the most popular fat burners in the industry for a reason. It may just be a BCAA, but studies have shown that it has the ability to transport fat to the mitochondria, which it can then be burned away as a fuel source for your body.

In other words, with L-Carnitine delivering fat to the mitochondria, you can be sure that your body is using fat as a fuel source rather than something else. This could ultimately lead to a decrease in body fat percentage, which additionally helps to accentuate your muscles and give you that ripped look.

L-Theanine: The Focus BCAA

L-Theanine can be an extremely beneficial BCAA for muscle growth, but it is perhaps actually more important for staying focused. Busy people are often sleep deprived, which means they have trouble focusing and performing efficiently during their workouts…that’s where L-Theanine comes in.

It has been shown to prevent sleep deprivation from effecting focus levels, which means that even if you didn’t sleep well the night before, you should still be able to get a good workout and maintain solid concentration levels all the way through.

Caffeine Anhydrous: The Primary Stimulant

Anhydrous is the purest form of caffeine in the world, making it the best stimulant you could possibly use. The high concentration of caffeine shoots your energy levels up and helps you maintain focus on the task at hand, which is why people tend to be less efficient when they haven’t had their morning coffee. You should always keep an eye out for a solid dose of caffeine anhydrous when searching for a pre workout supplement.

The Pros

  • Includes our favorite nitric oxide booster in a HUGE dosage
  • Uses high quality BCAAs
  • Contains the purest stimulant available (caffeine anhydrous)
  • Can improve both physical and mental performance
  • May improve strength and endurance through creatine monohydrate

The Cons

  • Can be intense if you’re new to pre workout
  • It is strictly available online…not at your local GNC

4 Gauge Conclusion

We feel that this pre workout covered just about every area of effective pre-lift nutrition including nitric oxide, BCAAs, and creatine. Usually, you need to take multiple supplements to get all three of those, but this way, you get them all in one supplement, which makes things easier and ensures proper growth/recovery.

There’s a lot of good to say about 4 Gauge and not really any bad, which made it an excellent supplement for us to test with nothing to lose. Our personal results with it were excellent, which is why we highly recommend 4 Gauge…it certainly lives up to the hype.
