Research Peptides · Europe
A standard isn’t something you claim. It’s what you repeat.
We hold what we make to the same rule: every batch third-party tested, every COA released with it.
Find Your Starting Point
Our Standard · Verified, Not Claimed
These are not shelf supplements. Every compound is synthesised against a >99% purity target, assayed by Janoshik, an independent analytical laboratory, and released with the certificate that proves it.
The Compound · The Instrument
Every compound ships as a lyophilised vial, reconstituted in the lab to whatever your protocol requires. The ONE% Pen is the instrument you load it into, machined aluminium, reusable, and not tied to any single compound.
The Proof · Verified, Not Claimed
Every batch is analysed by an independent laboratory before it ships. Identity confirmed by mass spectrometry, purity quantified by HPLC, and the certificate travels with the vial, not on request.
What Every COA Proves
From Education
The peptide market is full of claims nobody documents. We set out to build the opposite, and to show our work.
One molecule, three metabolic receptors. Why it became the reference point for the field’s most-watched research.
A fifteen-amino-acid fragment that turns up across tissue-repair research. The plain-language version.
Why Researchers Choose Us
The reasons labs across the EU standardise on ONE%.
Every batch ships with its Certificate of Analysis, available before you order, never after a dispute.
Identity by mass spectrometry, purity by HPLC against a >99% target, confirmed by an independent laboratory.
Cold-chain, discreet, tracked EU delivery in 24 to 48 hours. The logistics are handled so the research is not.
