Distracted. Unfocused. Going through the motions instead of actually training.

"I've tried a dozen pre-workouts. GAINHOUSE Pre is the only one that doesn't crash me an hour in. Clean energy, sick pump, and the watermelon flavor actually tastes good. This is my daily driver now."

"Started stacking the Pre and Creatine together. PR'd my bench after 3 weeks. I'm not saying it's magic—I'm saying the consistency and the fuel matter. GAINHOUSE delivers both."

"As a woman who trains seriously, I was skeptical. Most pre-workouts are just caffeine bombs. GAINHOUSE actually focuses me without the jitters. The multivitamin is solid too—energy all day."

Directions for Use

01

Assess Your Tolerance First

New to GAINHOUSE Pre? Begin with half a scoop (6g) mixed in 8–10 oz of cold water to assess your tolerance. Do not exceed one full scoop (12g) per day.

02

Mix & Drink

Once tolerance is established, mix 1 full scoop (12g) with 10–12 oz of cold water. Shake or stir well until fully dissolved.

03

Time It Right

Consume 20–30 minutes before your workout. Do not take within 6 hours of bedtime due to caffeine content.

04

Stack for Maximum Results

Combine with GAINHOUSE Creatine and Multivitamin for a complete performance stack. Train. Recover. Repeat.

BUILT BY THE
DISCIPLINED.
FOR THE DISCIPLINED.

GAINHOUSE wasn't born in a boardroom. It was built in the gym, between sets, by people who refused to settle for average.

THREE PILLARS.
ONE STANDARD.

01
Discipline Over Motivation

Motivation is temporary. Discipline is built. GAINHOUSE is for the people who show up when they don't feel like it — who do the work regardless of how they feel that day.

02
Transparency Over Hype

We don't hide behind proprietary blends or wild claims. Every formula is fully disclosed. Every facility is certified. You know exactly what you're taking and exactly why.

03
Performance Over Aesthetics

We don't care how the tub looks on the shelf. We care about what happens when you open it. Does it work? Does it support your training? Does it help you get better? That's the only question.

🏋️

WHY GAINHOUSE EXISTS.

We got tired of brands treating serious gym-goers like impulse buyers. Flashy labels. Celebrity endorsements. Under-dosed formulas hidden behind proprietary blends. Promises that couldn't survive a fact-check.

So we built something different. GAINHOUSE started as a commitment: create supplements that work, made in facilities you can trust, with labels you can read and ingredients you can research.

No celebrity face. No inflated claims. No compromise. Just clean, effective supplementation for people who take their training as seriously as we do.

If you're here, you're not looking for a miracle. You know results come from consistency, effort, and the right support system. We're part of that system.

GAINHOUSE. Strength Starts Here.

We believe 5am alarms are worth it. That discipline is the only shortcut. That the people who show up every day deserve fuel that works as hard as they do. That transparency isn't optional. That you earn your physique — and the right supplement supports that work.

YOUR WORK.
OUR FUEL.
