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.
A
4 Gauge is very effective. I also appreciate having other flavors available.
Z
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.
What's Inside
Every Ingredient Earns Its Spot
The complete label, exactly as it appears on the tub. Eleven active ingredients, every dose disclosed, nothing hidden under a proprietary blend.
L-Citrulline DL-Malate 2:16,000 mg
The pump ingredient, at a dose you can actually feel. Supports nitric oxide production and blood flow through your working sets.
Creatine Monohydrate1,000 mg
A supporting daily top-up, not a full standalone serving — if you want the complete daily creatine dose, that's what PowerPhase is for.
Acetyl L-Carnitine HCl500 mg
The acetylated form, chosen for its role in energy metabolism and mental clarity.
Red Beet Root300 mg
Naturally occurring nitrates that work alongside citrulline to support blood flow and endurance.
Coconut Water Powder300 mg
Natural electrolytes for hydration. You sweat when you train — this helps replace some of what you lose.
L-Theanine200 mg
Paired with caffeine to take the edge off. This is the reason 4 Gauge feels smooth instead of wired.
Caffeine Anhydrous150 mg
About a strong cup of coffee. Enough to feel it, not enough to wreck your evening.
Rhodiola Rosea (Root Extract)100 mg
An adaptogen traditionally used to support the body's response to physical stress and fatigue.
Sodium85 mg
Electrolyte support for hydration and normal muscle function while you train.
Potassium80 mg
Works with sodium to support fluid balance and normal muscle contraction.
Vitamin B12 (Methylcobalamin)5 mcg
The active, methylated form — supports normal energy metabolism.
Serving size 10 g (1 scoop) · 30 servings per container · 4 calories · 1 g carbohydrate per serving.
Other ingredients: natural flavor, stevia, beet root, malic acid, silica.

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 200 mg of L-Theanine for smoother, more sustained energy without the jitters or crash.
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. Others are supporting amounts rather than standalone doses — creatine at 1,000 mg, the electrolytes, the B12. Every one is printed on the label above so you can judge for yourself. If you want a full daily creatine serving, that's what PowerPhase is for.
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.
