What I train on

Why 4 Gauge Feels Better

Energy That Feels Good — First Rep to Last

Most pre-workouts are all spike, then crash. 4 Gauge delivers steady energy and locked-in focus from start to finish.

⚡

Consistent Energy

No huge spike. No sudden drop. Just steady energy that shows up and stays with you.

🎯

Locked-In Focus

Feel switched on — not overstimulated or scattered.

🔋

Extended Endurance

Energy that holds up deep into your workout — not just the first 20 minutes.

🛡️

No Crash

Walk out feeling accomplished, not drained. Smooth energy in, smooth energy out.

The Difference

4 Gauge vs. Typical Pre-Workouts

Built for performance — not a 20-minute stimulant hit.

4 GAUGE TOP SHELF

Great product! Great ingredients overall. No jitters as advertised. I get the gains and pumps that I need from this product. Also gives me the energy to complete a tough workout. I love the fruit blast flavor. I have been ordering the 4 pack for years now and will continue to order it. Highly recommend.

Good taste, no jitters, maximum versatility.

Do you know how hard it is to find a pre-workout that doesn't have sugar, or the fake sugars that ruin your (or maybe just my) stomach, AND that tastes good? I know that stevia is a fake sugar, but it is so much better on my stomach than Aspartame, sucralose, sorbitol, xylitol, etc. and I assume it is similarly better on the stomachs of other normal humans. Right now for caffeine/pre-workout my options are tea, coffee, and 4Gauge. Tea, I love, but it's too weak. Coffee, I dislike, and wont drink in the evening. That leaves the 4Gauge power that I can calibrate super accurately depending on what I'm doing and how much caffeine I want in my system for the next few hours.

Been using 4guage from last 5 years

Been using 4guage from last 5 years. It's perfect for me. I don't drink coffee and I'm sensitive to caffeine. So I can't have too much caffeine in my pre-workout. 4guage has just enough in it and the other ingredients are also help me to get a great workout each time.

Great pump and great flavor

Great pump and great flavor. Really happy to find a preworkout that gives the same pump, focus, and energy as others but with clean, natural ingredients. Will be a repeat customer 100%

Supplement facts
Founder of 4 Gauge
15+ Years Training · Why I Built This

Made By Someone Who Actually Uses It

"I got tired of supplements built for marketing instead of performance. So I built my own — manufactured in-house, with full control over every ingredient."

After years of trial and error with mainstream pre-workouts, I realized most were either under-dosed, over-stimulated, or filled with ingredients that had no business being there.

I wanted something I could trust. Something that worked consistently without leaving me feeling like garbage afterwards. So I created it. 4 Gauge is what I take, and it's built with the same care I put into my own training.

Questions

Frequently Asked Questions

No — 4 Gauge was specifically designed to avoid that. Most pre-workouts overload you with stimulants, creating a spike followed by a hard crash. 4 Gauge uses a balanced approach to deliver steady, controlled energy that stays consistent throughout your workout.
Each serving contains 150 mg of caffeine — about a strong cup of coffee. The difference is delivery: 4 Gauge pairs caffeine with L-Theanine for smoother, more sustained energy without the jitters or crash.
Most users feel the effects for 2–4 hours, depending on tolerance and body weight. No sharp spike, no sudden drop — just steady energy and focus.
Take 4 Gauge about 20–30 minutes before your workout with water. Many prefer a relatively empty stomach for faster absorption.
