Most pre-workouts rely on excessive stimulants and sensory overload to convince you they're "working." The result? Jitters, anxiety, tingling, and an energy crash. 4 Gauge was designed differently.

"Absolutely incredible — 100% the best pre-workout supplement. The endurance, strength, and muscle pump last right up until you eat, and it won't decrease."

Founder Philosophy

I Built the Supplement Brand I Wished Existed

4 Gauge was created for people who take fitness seriously — but are tired of the chaos, hype, and low-quality formulations that dominate the supplement industry.

Every formula is developed with performance, experience, and long-term health in mind. We manufacture in-house, use fully transparent formulas, and obsess over quality — because people deserve better from their supplements.

Frequently Asked Questions

Most pre-workouts are designed to overwhelm you with stimulation — massive caffeine doses, proprietary blends, and harsh ingredient combinations that can leave you feeling jittery, anxious, or completely drained afterward.

4 Gauge was built differently. Our formulas deliver smooth energy, clean focus, endurance, and performance without the chaos — with the key actives dosed to be felt and every amount printed on the label.

4 Gauge was specifically designed to avoid the harsh crash and overstimulation common in many pre-workouts. While everyone responds differently to caffeine, many customers describe 4 Gauge as providing smoother, cleaner energy compared to traditional high-stimulant pre-workouts.

4 Gauge uses high-quality ingredients and fully transparent formulas without proprietary blends. Our products are designed for people who care about performance, how they feel, and how their ingredients align with long-term health.

Many pre-workouts rely on excessive stimulants and poorly balanced formulas that create a short burst of energy followed by a crash. 4 Gauge was formulated with a more balanced approach to energy, focus, endurance, and performance — usable performance that helps you train hard without feeling wrecked afterward.

No. 4 Gauge uses fully transparent labeling, so you can see exactly what's inside and how much of each ingredient you're getting. We believe customers deserve to know what they're putting into their body.

4 Gauge works well for both experienced lifters and people newer to training. Because the formula provides smoother energy rather than overwhelming stimulation, many people find it easier to tolerate. As with any supplement containing caffeine, new users should assess their tolerance and start responsibly.

The ingredients that drive the effect are dosed to be felt: 6,000 mg of L-Citrulline DL-Malate, 200 mg of L-Theanine, and 150 mg of caffeine per serving.

Others are supporting amounts rather than standalone doses — creatine at 1,000 mg, the electrolytes, the B12. We print every one of them on the label so you can judge for yourself instead of taking our word for it. If you want a full daily creatine serving, that's what PowerPhase is for.

4 Gauge is designed for people who want to train hard, feel strong, improve performance, and build a healthier body — without relying on harsh, over-the-top stimulant formulas. It's built for people who care about both performance and long-term health.

Yes. 4 Gauge products are manufactured in-house with a focus on quality control, ingredient transparency, and consistency. Maintaining control over manufacturing lets us hold our products to a higher standard. Batches are also sent out for third-party testing.

Many people use pre-workout regularly as part of their training routine. Because 4 Gauge contains caffeine, individual tolerance and total daily caffeine intake should always be considered. Listening to your body and using supplements responsibly is important.

Every order is covered by a 30-day satisfaction guarantee. If 4 Gauge isn't right for you, reach out within 30 days of delivery and we'll refund or replace it — no hoops, no hassle.

We ship every weekday, so orders go out within 1 business day. US and Canada orders ship from our own warehouse; UK orders ship from our UK fulfillment center. Shipping is free on orders of 2 or more bottles within the US and UK.
