Built differently
Most pre-workouts rely on excessive stimulants and sensory overload to convince you they're working. The result is jitters, tingling, anxiety and a crash. 4 Gauge was designed around the opposite idea.
150 mg of caffeine balanced with 200 mg of L-Theanine. A moderate stimulant load that most people feel as steady energy rather than a spike, and that tapers without a crash.
No fairy dust, no proprietary blends. 6,000 mg L-Citrulline DL-Malate, 200 mg L-Theanine, 150 mg caffeine, with every number printed on the label.

“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.”
“Good taste, energy, and pump. I'd been looking for a formula without beta-alanine or betaine anhydrous, and this is the only company I found. Good formula.”
“Great tasting, no jitters or muscle tightness from too much caffeine. I'm super sharp and focused for about two hours. Great stuff.”

From the founder
4 Gauge was created for people who take training seriously but are tired of the hype, the chaos and the low-quality formulas that dominate the supplement industry.
I put my name on every formula, we make it in our own facility, and every dose goes on the label, because people deserve to know exactly what they're putting in their body. If you want the evidence behind each ingredient, I've written it up in the Research Hub.

Shop Pre-Workout →4 Gauge is a pre-workout built for smooth energy instead of overstimulation. The three actives that drive the effect are dosed to be felt: 6,000 mg L-Citrulline DL-Malate, 200 mg L-Theanine and 150 mg caffeine per serving, with every amount printed on the label. No proprietary blends, no beta-alanine, no sucralose, no artificial dyes.
4 Gauge is formulated to avoid the jitters and crash common in high-stimulant pre-workouts. Each serving pairs 150 mg of caffeine with 200 mg of L-Theanine, a combination customers consistently describe as steadier, cleaner energy. Everyone responds to caffeine differently, so assess your tolerance with a smaller serving the first time.
4 Gauge is naturally flavored with no artificial dyes, no sucralose and no sugar alcohols, but we don't call it "all natural." Actives like caffeine anhydrous and L-citrulline are the same synthetic-origin forms used in the research on them. Every ingredient and its exact dose is on the label so you can judge for yourself.
Because the stimulant load is moderate and balanced. 4 Gauge uses 150 mg of caffeine with 200 mg of L-Theanine rather than the 300 mg-plus stimulant stacks common in the category, and it contains no beta-alanine, so there is no tingling standing in for a real effect. Energy comes on steadily and tapers without a crash.
No. Every ingredient in 4 Gauge is listed with its exact amount per serving on the Supplement Facts panel, including the ones at supporting doses. You can see 6,000 mg L-Citrulline DL-Malate, 200 mg L-Theanine, 150 mg caffeine and the rest of the formula before you buy. Nothing is hidden inside a blend.
Yes. At 150 mg of caffeine per serving, 4 Gauge is easier to tolerate than most pre-workouts, which is why newer lifters tend to do well on it. Start with a smaller serving to assess your tolerance, then move to a full scoop. The energy is steady rather than overwhelming, so it works for a first pre-workout.
The ingredients that drive the effect are: 6,000 mg of L-Citrulline DL-Malate, 200 mg of L-Theanine and 150 mg of caffeine per serving. Others, like creatine at 1,000 mg, the electrolytes and B12, are supporting amounts, and we print every one so you can judge for yourself. For a full daily creatine serving, that's what PowerPhase is for.
4 Gauge is for people who train hard, including lifters, runners and athletes, and want energy, focus, pumps and endurance without the crash, itch or anxiety of high-stimulant formulas. It's used by men and women at every experience level, and it suits anyone who cares about what's in their supplements as much as how they perform.
Yes. 4 Gauge is manufactured in our own facility in Ogden, Utah, which is GMP certified through the Utah Department of Agriculture. Every batch is also sent to an independent lab and tested for heavy metals, microbials and potency. Controlling manufacturing ourselves is how we keep every bottle consistent with the label.
Many customers use 4 Gauge on every training day. Each serving contains 150 mg of caffeine, so count it toward your total daily caffeine from coffee and other sources, and skip it late in the day if caffeine affects your sleep. Take it on the days you train, and you don't need to cycle off it.
Every order is covered by a 45-day satisfaction guarantee: if 4 Gauge isn't right for you, contact us within 45 days of delivery for a refund or replacement, and we pay return shipping if we need the bottle back.
