About ONE%

Every Compound.
One Standard.

ONE% exists on a simple conviction: a supplier should be able to prove what it sells. Every compound we ship is third-party tested, batch-referenced and released with its certificate, and shipped safely across the EU.

Why We Exist

Most suppliers cannot tell you what is actually in the vial. We publish it, batch by batch.

Walk into most peptide suppliers and you meet the same thing: long lists of compounds, and certificates of analysis that never quite materialise. Listing a compound is easy. Proving it is the hard part, and it is the part almost nobody delivers.

ONE% was built to be the opposite. Our range spans the metabolic, recovery, growth, skin and longevity categories that define serious peptide research today, and it keeps growing. Each compound earns its place on merit, and each is held to the same uncompromising bar before it ever reaches a bench.

That is what the name means. ONE% is not exclusivity for its own sake, it is a standard. This market cuts corners where no one is looking. We decided to be the supplier that doesn’t, and to put the proof in your hands before you ever place an order.

What We Believe

Six Non-Negotiables.

01

One Bar, Every Compound

The range grows as the research does. The standard it has to clear does not move.

02

Proof, Every Batch

Independent mass-spec and HPLC on every batch. Release is earned through testing, never assumed.

03

Documentation First

The Certificate of Analysis should arrive before the order, not after the complaint. Ours is on request.

04

Cold-Chain By Default

Temperature-conscious, discreet, tracked delivery across the EU is the standard here, never an upsell.

05

The Instrument Is Separate

Compounds ship as vials. The ONE% Pen is a reusable instrument, bought once, not tied to any compound.

06

Integrity In, Integrity Out

Research integrity starts with material integrity. What leaves our bench is exactly what reaches yours.

The Pillars

How We're Different

A, RANGE

Built To Grow

We add compounds as the research earns it. Every new one clears the same testing before it ships.

B, VERIFICATION

Proof, Per Batch

Third-party mass-spec and HPLC on every batch, tied to a traceable Certificate of Analysis.

C, HANDLING

Cold-Chain Default

Lyophilised, sealed, and cold-chain dispatched within Europe so what leaves us is what reaches you.

“A standard is not what you say once.
It is what survives every batch.”
