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 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. It's what I'd give to my friends. And it's built with the same care I put into my own training.

Frequently asked questions

Is 4 Gauge a health preworkout?

4 Gauge is built with long-term performance in mind. It avoids excessive stimulants, artificial sweeteners, and proprietary blends. The formula focuses on proven ingredients at responsible doses so you can train hard without beating up your nervous system. Healthy performance isn't about spikes. It's about sustainability.

Does 4 Gauge 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.

Is 4 Gauge a natural preworkout?

Yes.
There are no proprietary blends and no artificial sweeteners. Every ingredient and dose is fully disclosed on the label.
If it’s in the formula, it earns its spot. If it doesn’t serve performance, it’s not in there.

Q: 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.

Who is 4 Gauge 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.

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.

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.

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.

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.

Does it contain artificial sweeteners?

No.

No proprietary blends.

No hidden doses.

No artificial sweeteners.

Full label. Full transparency.

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.

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.
