About 4 Gauge Pre-Workout

The kind of bottle 4 Gauge has screams “Look at me, I’m different” in any gym store. So few companies invest in bottle design, and we’ve seen hundreds that try to impress with graphics, drawings, and some animal claws and fangs. It also makes you want to recycle the bottle, which is always a good thing. Here’s what we noticed:

  • 6 g of Citrulline Malate. Whoa! 4 Gauge just shotgunned a whole bag of pumps at our faces.

  • Caffeine-Theanine stack. For those who love caffeine, but hate the side effects.

  • Stress and mood. A bit of a nootropic effect.

Other Ingredients: Dextrose, Erythritol, Natural Flavors, Xylitol, Monk Fruit Ext. (standardized to Mogrosides), Silica, Swerve® (Erythritol, Oligosaccharides, Natural Flavors).


Mix two level scoops of 4 Gauge powder in 10-12 fl. Oz./300-350ml of water or juice and drink 20-30 minutes before training. Once tolerance has been assessed and you are looking for an extra energy boost, you can take 3 or 4 level scoops.

4 Gauge Pre-Workout: Ingredient List

  • L-Citrulline DL Malate. 4 Gauge wants to impress us by starting with six grams of this scientifically proven pump booster and vasodilator. It helps optimize blood flow and nutrient uptake, makes you get massive pumps and improves performance inside the gym.

  • Creatine. Creatine is one of the most studied ingredients out there and with good reason. Creatine is popularly known for its muscle recovery benefits, where it helps repair muscle tissue faster which then leads to users coming back to the gym sooner just as good or better than ever. The 1 gram dosage is really wanting, though.

  • Acetyl L-Carnitine. This is an improved version of the popular L-Carnitine. More than fat burning, this is also known to exhibit fatigue-reducing properties, reduce cellular damage brought by exercise, and boost focus. Acetyl-L-Carnitine’s fatigue-reducing benefit complements Creatine’s energy boosting perk.

  • Red Beet Root Extract. An odd addition in a world where just about everything is lab-made. Red beet root extract is known to help with blood pressure regulation, stamina enhancement and detoxification properties. In a pre workout blend, its main goal is to sustain the pump action brought by citrulline.

  • Caffeine. Caffeine at 150 mg is tame and not so much of a threat compared to supplements that abuses caffeine’s cheap price. The dosage is just over one cup of coffee’s worth of caffeine.

  • Theanine. Theanine is found in and is known for anti-stress and relaxing benefits. Combined with caffeine, theanine acts as a buffer that protects users from jitters and other stimulant side effects. 

  • Coconut water. It’s not everyday you get to see coconut water added in a pre workout blend. However, coconut water does promote electrolyte replenishment and muscle hydration. These two properties reduce muscle recovery as well as help prevent problems like muscle cramps.

  • Rhodiola Rosea. Rhodiola rosea is an adaptogen. Adaptogens are plant-based ingredients known to reduce the effects of anxiety, stress, and distractions. 

Overall, we think 4 Gauge is a different kind of pre workout and that’s a good thing. The way the formula was made was to ensure users get what they bought it for: pumps, energy, focus, and recovery. Each ingredient also displays synergy amongst themselves, with each compound supporting the other.

Who is 4 Gauge Pre-Workout made for?

4 Gauge has to be made consumers who aren’t comfortable with the idea of taking too much caffeine, but also want something with just enough energy and pump to let them do what they have to do inside the gym. 

What are 4 Gauge Pre-Workout’s benefits?

4 Gauge can help improve explosiveness, boost stamina, improve mental focus, and overall just get you pumped out of your mind.

4 Gauge Pre-Workout: Side Effects

Caffeine may not be that much of a problem in 4 Gauge. After all, we’re just getting 150 mg of it in total. However, 4 Gauge still wants to make sure stim side effects don’t get in the way of our training by adding theanine. 

Theanine has its own separate perks, but it will also cancel out the unwanted effects of caffeine like nausea, headache, and jitters.The more concerning part of their formula has to do with their use of sugar alcohols xylitol and erythritol. Some say they’re harmless, others say they contribute to long-term damage. One thing is certain: too much of any sugar alcohol can lead to intestinal distress and cause digestive issues.

4 Gauge Pre-Workout: pros and cons


  • Up to date formula. No oldies allowed.

  • Synergy. Each compound can act on its own and provide amazing things, but they work best together.

  • Caffeine and theanine stack. There’s actually more theanine than caffeine which is rare.

  • Awesome bottle design. Definitely a must-have for collectors.


  • Pricey. 280 grams for $45.00 is really high.

  • Sugar alcohols. Monk fruit and stevia are better options.

  • Low-dose creatine. 1 gram ain’t going to do much.

Pricing info

4 Gauge Pre-Workout: Summary

4 Gauge is built to do whatever it takes for you to smash your PRs and just chill and relax during muscle recovery. You have pumps, get a good dose of focus, and a clean yet energized feel. 

Quality dosing and synergy plus amazing marketing makes 4 Gauge an absolute winner for those looking for something eye candy yet also functional. The only drawback is the price per bottle. Far too many supplements offer more robust formulations for much lesser. However, if you really want to collect the bottle or just want to see what 4 Gauge is like, we think it’s a nice buy.

Should you take 4 Gauge? If you can pay the price and don’t mind the mild energy boost, then yes.
