Who is the Producer?

Roar Ambition, the producer of 4 Gauge muscle booster, is one of the popular premium supplements. The company prides itself on 100% natural products that range from testosterone boosters to fat burners. Users of their products for building muscle mass include top athletes and bodybuilders from different parts of the world – including UFC fighters such as Diego Sanchez and bodybuilding legends like Robby Robinson.

Another thing people like about Roar Ambition is that they make all their products in FDA approved and GMP certified facilities. Put differently, they produce all their products under strict guidelines and therefore, they are of higher quality.

The 4 Gauge Sports Nutrition Ingredients

Roar Ambition advises users to use the sports nutrition within 20-30 minutes before their workout sessions. For better results, mix 2 scoops of 4 Gauge in a 300-350 ml jar of juice, water or any drink of your choice. The following are the key ingredients in the product:

L-Citruline DI-Malate

L-CItruline DI-Malate is an amino acid that converts into L-Arginine in the kidneys. If you already know the purpose of L-Arginine in the body, that should sound good. L-Arginine improves blood circulation and heightens the level of nitric oxide in the body. That means that you will experience more intense muscle pumps when working out in the gym. However, L-arginine has poor absorption rate if supplemented orally. That is why Roar Ambition opted for L-Citruline, which has a great absorption rate and increases levels of nitric oxide in the body. And because 4 Gauge dietary supplement contains more L-Citruline (6,000 mg), you should be ready for better effects.

Creatine Monohydrate

Creatine is among the well-known supplements on the market and people have used it for many decades. it boosts the strength level and endurance during a workout. In other words, it will help you push out the last 2-3 reps and gain more muscle mass.

Acetyl L-Carnitine

Studies have proved that Acetyl L-Carnitine increases alertness, helping the user to focus on attaining his/her goals during a workout session. If you mostly, check your social media accounts during a workout session, the ingredient will keep you concentrated on attaining your goals during a session. What’s more, increased focus enhances mind-muscle connection when lifting weights and therefore you will utilize every rep in the best way and progress in a better way. The ingredient produces great results.

Red Beetroot Extract

The other common name for Red Beetroot is Beta Vulgaris. It is known to contain high levels of nitrate, which the body converts into nitric oxide. Nitric oxide dilates the blood vessels and offers a wonderful muscle pump. In the end, that provides the user with an amazing feeling that helps him/her workout harder in the gym and lift heavier weights.

Many studies have shown that the ingredient can boost your aerobic performance and because Roar Ambition has included 300 mg in the product, you should be ready for greater benefits. Another reason you should go for the product is that red beetroot helps reduce blood pressure. Even though the latter is not important in workouts, you should know that beetroots have no side effects.

Coconut Water Powder

Coconut water is a wonderful source of potassium, which improves the overall body health. Most importantly, coconut water powder contains electrolytes that will keep you hydrated in intense workout sessions. You will hardly get the ingredient in any other product in the market. It has helped 4 Gauge standout as a great product in the market.

L-Theanine and Caffeine

L-Theanine is an effective neurotransmitter that reduces the level of stress and improves the user’s focus. However, Roar Ambition has combined with caffeine to enhance its effects. The two ingredients – L-Theanine and Caffeine – work synergistically to form a ’Smart Caffeine’ that provides the user with a stimulating effect of caffeine without any side effects. The combination is known to prolong effects of caffeine and to reduce chances of a crash after a workout session. Therefore, you will remain energized in an entire workout session. You will never go home before a session has ended.

Rhodiola Rosea

Rhodiola Rosea is a herb proven to reduce physical exhaustion excellently, therefore, minimizing physical exhaustion that leads to fatigue. That means that you will remain fresh and ready to complete any workout session. The ingredient also enhances cognitive functions and helps the user concentrate and focus on his/her workout. Rhodiola Rosea improves the mood and is more effective in minimizing stress levels. That ensures that the user is equipped with a proper mindset to attain any workout goal. The ingredient is more effective at 50 mg doses. Therefore, the 100mg dose in 4 Gauge muscle enhancer is more than you actually need to attain your workout goals.

  1. Lovely pre workout, clear effect after about 30min, the effect lasts for long training sessions. It doesn’t give any itching feeling. Overall the best pwo I’ve used. There is only one downside, the taste is very sour and if you stack extra scoops it can be difficult to drink. But would definitely recommend this pwo!

    • It works well, nice and clean, no jitters or itchiness due to Beta-Alanine. No rough comedown either.
      The only letdown for me is the flavour, it’s sour as hell and can sometimes be grainy, even with only one scoop

  2. I like how you pointed out that 4 Gauge actually goes beyond by giving you that spur of emotions to keep yourself motivated. It’s not just muscles and masses; it’s the discipline to finish a workout that matters.

  3. 4Gauge is awesome, the taste alone wakes me up for the gym! No jitters or crash! The only problem I have had is the bottles were clumpy on arrival which was disappointing, however I still think it’s one of the best I’ve tried!

  4. Pre-workout supplements are the best. Since I have been taking them, I always feel so much better after a good workout. I have been seeing nice gains and my energy level has never been better.

  5. Looks like it covers holistically the factors involved in a productive workout. Hope it gives that boost that I need.

  6. Is it really important for me to have a pre-workout supplement? I am new to this and just wasn’t sure if it was going to be all that helpful. I guess I could try it out and see how I feel after, right?

    • I believe so. I felt the same way that you did at first, but after I started using 4 Gauge, I could not believe that I waited so long to give it a try. The ingredients are amazing and I always feel great after I have it. Good luck!

  7. Coconut Water Powder? I have read great things about this as a supplement. I was really surprised to see it included in a product like this. At least it would be natural and easy to digest inside your body. Would it be possible to assume that taking too much of this might upset my stomach?

  8. So this is something you take before you work out and it gives you the same results as them shakes and what not? I may try this. I was using some whey with little to no results. In fact, I felt it was making me FAT. This makes me think I have been doing it wrong or something.

  9. I follow someone on Youtube who was mentioning this and I had to research it. His before and afters are AMAZING! I guess he was not able to gain muscle his whole life. He was a string bean! You would not even believe he is the same guy as before. I was blown again. This product sounds amazing.

    • Can you provide a link to the youtube video? Definitely interested in hearing what this guy had to say.











    I use this product and honestly it isn’t as great as advertised. The only thing that I’ve ever noticed using this preworkout is the muscle pump that comes with it. Otherwise the taste is decent. I wouldn’t buy it again because it is so pricey and it really did not give me the any extra energy.











    Love this stuff, it works phenomially. However, it taste like shit, literally like I threw up in my mouth! I mix with a flavored bcaa to get it down, but after about 30 Min. I feel like superman.

  12. Didn’t care much for it at all. Maybe I got a bad can or something? I opened it up and at the top was a hard golf ball sized clump. It tasted awful too, really sour. Reminded me of a watered down “cry baby” gum ball. The energy boost was decent and felt cleaner then previous pre workout powders I’ve used.
