The Problem
Most pre-workouts are a stimulant arms race
More caffeine. More stimulants. More "feel something" ingredients. The result is usually a workout that feels worse — not better.
✕ Heart racing
✕ Jitters
✕ Itchy skin
✕ Energy crash
✕ Trouble sleeping
✕ Anxiety
Made For You
These free samples are built for…
4 Gauge isn't for everyone chasing the biggest stimulant hit. It's for people who want to actually feel good while they train.
✓ People who hate jitters and crashes
✓ Former C4 users wanting something cleaner
✓ Former Bucked Up users tired of feeling wired
✓ Coffee drinkers who want better workouts
✓ Lifters who care what goes in their body

If you've been searching for a pre-workout that helps you perform without feeling overstimulated, this is your zero-risk way to find out.
The Difference
What makes 4 Gauge feel different
⚡
Clean Energy
Smooth, usable energy that builds instead of spikes.
🎯
Laser Focus
Locked in from your warm-up to your last rep.
💪
Better Pumps
Improved blood flow for fuller, stronger sets.
🛡️
No Crash
Steady through your session and long after.
🚫
No Tingles
No itchy beta-alanine prickle. Just performance.
😌
Feel-Good Workouts
Energized — not overstimulated or anxious.
3 Flavors · 3 Workouts
One workout of each flavor
Taste all three and pick your go-to before you ever commit to a full bottle. Most people order a full round of the one they liked best. Some can't decide. That's a good problem.
Fruit Blast
Sweet. Bold. Classic.
Frozen Lemonade
Crisp. Cool. Refreshing.
Piña Colada
Tropical. Smooth. Different.Under The Hood
Full doses. No proprietary blends.
Every gram on the label, nothing hidden. The 200mg of L-theanine against a coffee-sized 150mg of caffeine is why 4 Gauge feels smooth instead of shaky — a deliberate ratio, not an accident.
Citrulline — 6,000 mg
Supports blood flow and fuller pumps that last through your session.
Creatine — 1,000 mg
Supports strength, power, and performance — the most-researched there is.
Caffeine 150 mg + L-Theanine 200 mg
Smooth, focused energy without the spike-and-crash or the jitters.
✕ No artificial dyes
✕ No sucralose
✕ No proprietary blends

From The Founder
Why I created 4 Gauge
I was tired of choosing between pre-workouts that did nothing and pre-workouts that made me feel terrible. I wanted something that delivered real performance, smooth energy, and a better overall workout experience.
Honestly? These samples cost us more than $4.95 to send. We do it anyway — because once you've trained on 4 Gauge, the difference isn't something I have to convince you of.
— Connor SouthworthFounder, 4 Gauge
Why Would We Give It Away?
Because trying it beats reading about it
Trying a new pre-workout shouldn't mean gambling $45 on a full bottle. So we take the gamble instead — we lose money on every sample pack we send. That's also why it's one per customer.

No — and we want to be crystal clear about it. This is a one-time $4.95 charge. No subscription, no membership, no auto-billing, nothing to cancel. Ever.
Three single-serve pouches: one Fruit Blast, one Frozen Lemonade, one Piña Colada. Each pouch is one full workout — pre-measured, no scooping.
A responsible, coffee-sized 150mg, paired with 200mg of L-Theanine so it comes on smooth — enough to feel it, without the jitters, spike, or crash of high-stimulant pre-workouts.
Email us and we refund your $4.95 — shipping included. No hoops, no hassle.
We ship all orders within one business day.
Because we lose money on every one we send. It's a sample program, not a store — when you're ready for more, a full round of 4 Gauge is 30 workouts.
