Our Story

Two brothers. One ritual.

OXYNSUPPS is built by Mattias and Samuel — two Estonian brothers who've lived in gyms their whole lives. Caffeine has been part of our daily ritual for as long as we can remember, powering long sessions and longer days. So we built the pre-workout we actually want to drink.

— How It Started —

Gyms, sports, caffeine. As long as we can remember.

We've spent most of our lives in gyms. Early-morning lifts before school, evening sessions after long workdays, weekend long runs, and the days when nothing felt right and we trained anyway. The one constant.

Caffeine became part of the rhythm. A scoop before the heavy session. A scoop before the long workday. A scoop for the in-between days when motivation alone wasn't going to cut it.

"We're not reinventing the category. We're making the pre-workout we already drink."

OXYNSUPPS is a clean, properly-dosed pre-workout built by two brothers who've trained their whole lives — for everyone else who has too. We live in different cities now, but the gym and the ritual stayed the same.

— The Founders —

The brothers. Mattias & Samuel.

No corporate boardroom. No investor slide deck. Two brothers — lifelong athletes — building the pre-workout we'd actually want to drink ourselves.

— What We Stand For —

Three non-negotiables.

The line we will not cross. Not for cost. Not for margin. Not for anyone.

I.

Clinical Doses

Every active ingredient hits the exact dose the peer-reviewed research used. 6g L-Citrulline, 3.2g Beta-Alanine, 2.5g Betaine. Not "1g and we'll call it 'clinical.'"

II.

Radical Transparency

No proprietary blends. No mystery numbers. Every milligram is printed on the label and listed on the website. If we can't tell you exactly what's in the tub, you shouldn't trust the tub.

III.

Clean Standards

Manufactured in a GMP-certified facility under EU food-safety law. Third-party tested every batch. Lot number on every tub. The standards we'd want for our own bodies.

— The Difference —

What the math actually looks like.

Side by side, against the average store-brand pre-workout most European athletes are currently buying.
