WHY I BUILT THIS

Made By Someone Who Actually Uses It

"This is exactly what I take before my own training."

I got tired of pre-workouts built for hype instead of performance.

So I built my own.

Most are either under-dosed, overloaded with stimulants, or filled with ingredients that don’t belong.

I wanted something simple:

  • Clean energy
  • No crash
  • Performance that actually holds up

So we manufacture 4 Gauge in-house—with full control over every ingredient.

4 Gauge is what I take before I train.
It’s what I’d recommend to anyone who actually cares about performance.

Frequently asked questions

How is 4 Gauge different from other preworkouts?

Most pre-workouts are designed to make you feel something.
4 Gauge is designed to help you perform.
That means:
    •    Responsible caffeine dosing
    •    No hidden blends
    •    Ingredients that support strength, endurance, and focus
    •    No unnecessary filler
You shouldn’t need to “recover” from your pre-workout.

What makes this a clean preworkout?

A clean preworkout is one that delivers effective results without unnecessary ingredients or harsh side effects.

4 Gauge is considered a clean preworkout because it focuses on:

  • Clinically effective doses of proven ingredients
  • No proprietary blends—you know exactly what you’re getting
  • No beta-alanine, so no tingling
  • Balanced stimulation for smooth energy and focus

Everything in the formula is there for a reason—to support performance in a way that feels good and can be used consistently over time.

How is this different from high-stim preworkouts?

Most high-stim preworkouts rely on large amounts of caffeine and other stimulants to create an intense energy spike.

While that can feel powerful at first, it often leads to:

  • Jitters or anxiety
  • Energy crashes
  • Inconsistent performance

4 Gauge takes a different approach. It uses a moderate dose of caffeine paired with L-theanine to create smoother, more stable energy.

The result is a preworkout that supports performance without overwhelming your system—so you can train hard and still feel good afterward.

What does a clean preworkout feel like?

A clean preworkout should feel smooth, controlled, and consistent—not overwhelming.

With 4 Gauge, most people describe the experience as:

  • Steady energy that builds naturally
  • Clear, focused mindset without feeling wired
  • No sudden spike or crash

Instead of feeling overstimulated, you feel locked in and ready to train. It’s energy you can rely on—not something you have to manage.

Does this preworkout cause jitters or crashes?

No.
I built 4 Gauge specifically to avoid that wired, shaky feeling most pre-workouts give you. It uses 150mg of caffeine balanced with L-theanine, so the energy feels smooth and controlled — not chaotic.
You should feel locked in. Not overstimulated. And when you leave the gym, you shouldn’t feel wrecked.

Does this preworkout have beta-alanine (and will it cause tingling)?

No—4 Gauge does not contain beta-alanine, so it won’t cause the tingling sensation that many preworkouts are known for.

That “tingle” (called paresthesia) is often mistaken for effectiveness, but it doesn’t actually improve performance. It’s just a side effect of beta-alanine.

4 Gauge is designed to deliver real performance benefits—like improved focus, endurance, and pump—without unnecessary ingredients or distracting side effects.

Is this a healthy, natural preworkout?

4 Gauge is designed to be a clean, well-balanced preworkout that supports performance without unnecessary ingredients or harsh side effects.

It uses a mix of naturally derived ingredients and clinically studied compounds to deliver real results—like improved energy, focus, and pump—without relying on excessive stimulants or artificial fillers.

You won’t find proprietary blends, and every ingredient is included at a purposeful dose. It’s also formulated without beta-alanine, so there’s no tingling sensation.

While no preworkout is “perfect” for everyone, 4 Gauge is built to be a healthier, more consistent option compared to typical high-stimulant formulas—something you can use regularly without feeling run down or overstimulated.

Is 4 Gauge suitable for sensitive stomachs?

A: Absolutely. Our formula is designed for easy digestibility and contains no artificial additives that often cause stomach upset.

Does it contain artificial sweeteners?

No.

No proprietary blends.

No hidden doses.

No artificial sweeteners.

Full label. Full transparency.

Who is this preworkout NOT for?

4 Gauge isn’t designed for everyone—and that’s intentional.

It may not be the right fit if you’re looking for an extremely high-stimulant preworkout that creates a strong rush, intense buzz, or “amped up” feeling.

Some people prefer that kind of experience, but it often comes with trade-offs like jitters, crashes, or inconsistent performance.

4 Gauge is built for something different:

  • Smooth, controlled energy
  • Clear focus without feeling wired
  • Consistent performance you can rely on

If you want a preworkout that feels clean, balanced, and repeatable day after day, this is likely a better fit.

Who is this preworkout built for?

Serious lifters.

Not influencers. Not stim junkies. Not people chasing a tingle.

If you care about clean energy, real focus, and repeatable performance - this is for you.

Is this preworkout good for beginners?

Yes—4 Gauge is a great option for beginners, especially if you’ve had bad experiences with harsh or overly stimulating preworkouts.

Many first-time users are surprised by how different it feels. You still get noticeable energy and focus, but without the jitters, anxiety, or crash that often come with high-stimulant formulas.

It’s a more controlled, predictable experience, which makes it ideal whether you’re new to preworkouts or just looking for something you can use consistently.

Can I take 4 Gauge every day?

If you train consistently, yes.

it's not overloaded with stimulants, so most people don't feel the need to cycle it aggressively. That said, listen to your body. Performance is long-term.

When should I take it?

One scoop, 20-30 minutes before training. Energy builds as your warm up and peaks during your working sets.

Simple. Effective. Repeatable.

What should I expect the first time I take it?

Most people notice smoother energy and stronger focus right away.

Not a spike. No a rush.

Just controlled intensity.

And the real difference?

You'll feel great when you're done.

How much caffeine is in 4 Gauge?

150 mg per serving.

About the same as a strong cup of coffee - enough to feel, not enough to regret. If you're sensitive, start with a half scoop and assess from there.

Why not more stimulants?

Because more isn’t better — better is better.
Most high-stim pre-workouts are built to overwhelm you. You feel a rush, your heart rate spikes, and for a short window you think it’s working.
But performance isn’t about chaos. It’s about control.
4 Gauge uses 150mg of caffeine because that’s enough to enhance energy and focus without frying your nervous system. It’s balanced with L-theanine so the energy feels smooth and intentional — not jittery or scattered.
If you need 350–400mg of caffeine just to train, that’s not a supplement issue. That’s a recovery issue.
I built 4 Gauge for people who want to perform consistently — not people chasing a spike.
