A Quick Look at 4 Gauge Pre-Workout

“I honestly just got sick of gimmicky fitness supplements. I wanted something better…so I made it,” shares Conner Southworth, owner of 4 Gauge. The solution? Connor formulated and packaged an “explosive” pre-workout into a container mimicking a shotgun shell.

Despite its intense persona, 4 Gauge is a mildly caffeinated pre-workout containing natural ingredients. It blasts off to consumers worldwide, but there are things you should know before you buy.

Before You Buy

• For cost savings, you can purchase “rounds” (aka bulk options).
• Although 4 Gauge ships worldwide, select countries are excluded and fees may apply. Check their website for details.
• 4 Gauge provides 150 milligrams of caffeine, which may be too little, too much, or just right, depending on your caffeine tolerance and preference.

Is 4 Gauge Pre-Workout Worth It?

Costing $1.77 per serving, or $1.50 with the current discount, 4 Gauge is somewhat pricey, considering its inadequate doses of some key ingredients. This is particularly notable compared to products like Transparent Labs BULK, which costs $1.66 per serving while providing research-backed doses and being third-party tested.

However, 4 Gauge has positive features and reviews worth considering before your next workout session.

Experience Using 4 Gauge Pre-Workout

GGR Senior Editor Nicole Davis, CPT, PN1-NC, sampled 4 Gauge and shared her firsthand experience: “This doesn’t have a ton of caffeine but still gives you a nice pick-me-up—and definitely a pump. I didn’t love the taste of the flavor I tried, but the effects were worth giving it more than one shot!”

Price Per Serving

A 30-serving container is $52.95, equating to about $1.77 per serving. Bulk purchase options, referred to as “rounds” (meaning containers), offer additional savings:

• Two rounds (60 servings): $105.90 ($1.77/serving) with free, fast shipping
• Four rounds, called the “Ultimate Ammo Crate” (120 servings): $211.90 ($1.77/serving) with free, fast shipping

While the cost per serving is the same for single and multi-round purchases, opting for a single container adds a $7.95 shipping fee. 

RELATED: Best Cheap Pre-Workout

It’s also worth noting that all purchase options are usually discounted, including the single container previously bought by GGR staff writer Lauren Strong for $45, the same price it’s currently listed for. This consistent discounting may be intentional, creating a sense of urgency among potential buyers.

Other Third-Party Retailers

• Amazon: 42.50/30 = $1.42/serving
• Walmart: 39.95 = $1.33/serving 
• Hi-Health: 39.95/30 servings = $1.33/serving

Formulation

Nicole rated the formulation  2 out of 5 stars, primarily due to insufficient dosages in key ingredients. Here’s what to know about 4 Gauge’s formula. 

Caffeine Anhydrous (150 milligrams) 

A staple in pre-workouts, caffeine¹ enhances focus, mood, energy levels, and physical performance. The 150 milligrams in 4 Gauge is less than the typical 200-milligram recommendation but remains a viable option for those sensitive to caffeine, new to pre-workouts, or who consume caffeine from other sources.

RELATED: Best Pre-Workout for Beginners

Creatine Monohydrate (1 gram)

Creatine² is known for effectively increasing aerobic capacity, speed, and muscle gains. In fact, with proper and consistent training over four to 12 weeks, supplementing with creatine can add an extra two to four pounds of muscle mass!

4 Gauge includes creatine monohydrate, the most researched form of creatine. However, 1 gram per scoop is below the recommended 3- to 5-gram daily dose.

RELATED: Best Pre-Workout with Creatine

Citrulline Malate (6 grams)

Let’s first help clear any confusion: 4 Gauge regularly mentions L-citrulline on its website, but you’ll find L-citrulline dl-malate on the ingredient list. While both are ingredients to look for in a pre-workout, they’re not the same.

L-citrulline is an amino acid found naturally in fruits like watermelon. It helps boost nitric oxide and dilate blood vessels, with research³ supporting the positive effects of L-citrulline on exercise performance and recovery.

Combining malate with L-citrulline, citrulline malate may offer more ergogenic effects—like reducing muscle soreness and increasing muscular endurance—than taking L-citrulline alone. Although 8 grams is the recommended dose, the 6 grams of citrulline malate in 4 Gauge may be enough to elicit benefits³.

Other Ingredients

• Red beet root extract (300 mg): Beetroot⁴ enhances exercise performance and reduces muscle soreness by increasing blood flow through nitric oxide production⁵ and vasodilation. 
• Acetyl l-carnitine (500 mg): Carnitine⁶ may prevent fatigue and reduce muscle soreness with potential roles in weight loss, brain health⁷, and other health conditions. 
• Coconut water powder (300 mg): Rich in essential electrolytes, such as sodium, potassium, magnesium, and calcium, coconut water⁸ is a great hydration source (although the amounts are trivial on the Supplement Facts label).
• L-theanine (200 mg): 4 Gauge strategically combines l-theanine⁹, known for its calming effect, and caffeine to create “smart caffeine.” Their synergistic effect may enhance mental performance while minimizing caffeine’s side effects.
• Rhodiola rosea root powder (100 mg): Rhodiola rosea primarily works as a nootropic¹⁰, a “cognitive enhancer” that can enhance mental focus. Research¹¹ also suggests it may improve exercise performance, including enhancing explosiveness and reducing recovery time. 

Taste and Solubility 

Nicole tasted the Fruit Blast flavor, rating it 4 out of 5 stars, with mixed feedback: “It’s not very sweet and has an almost sour tinge. While it wasn’t my favorite, it could be appealing for those who prefer less sweetness.”

But Nicole was impressed with the product’s solubility, awarding it a perfect 5 out of 5 stars. She noted, “It mixes well and easily—no floaties.”

Side Effects

Nicole gave 4 Gauge 5 out of 5 stars in the side effects category, excitedly commenting, “No tingling, yay!” But this is due to the fact that 4 Gauge lacks beta-alanine, which is the pre-workout ingredient responsible for the harmless tingling sensation.

Third-Party Testing 

We prioritize third-party testing in the unregulated supplement industry, especially for athletes subject to drug testing. Although 4 Gauge claims to contain no banned substances, Nicole notes, “It lacks third-party testing, but the label is transparent, meaning no proprietary blends are hidden,” resulting in a modest 2-out-of-5-star rating for this category.

Bottom Line

Fuel your body with a delicious pre-workout supplement with nutrients and 14 active ingredients for an energy-boosting workout.

JYM Pre-Workout was formulated by Dr. Jim Stoppani, a bodybuilding athlete and coach. It shares similarities with 4 Gauge, such as providing 600 milligrams of citrulline malate and lacking third-party testing.

However, JYM Pre-Workout offers more flavors and an even more robust formula, including double the amount of caffeine and creatine compared to 4 Gauge. It also contains various amino acids, including BCAAs for muscle growth, and more nootropics, like alpha-GPC and Huperzine A. Despite its higher price point and serving size, the extensive ingredient list makes it a standout option.

Final Verdict of Our 4 Gauge Pre-Workout Review

After reviewing 4 Gauge pre-workout based on current data and with first-hand testing experience, here are our final takeaways:

• Provides natural and key pre-workout ingredients, like caffeine and citrulline malate, but not all ingredients are dosed according to scientific recommendations.
• Contains a relatively low dose of caffeine at 150 milligrams, which may be suitable for some but not enough for others.
• Lacks third-party testing, which is especially risky for athletes.
• Honors a money-back guarantee regardless of the return reason.
• Customers generally review 4 Gauge as an effective pre-workout product.
• Fairly pricey compared to competitors that are effectively dosed.

Overall, your experience with 4 Gauge as a pre-workout product may vary, although many consumers, including GGR’s testers, report enjoying muscle pumps and energy without experiencing jitters.
