The atelier

Science as a craft.

How we produce, test and ship every vial — from lyophilisation under argon to independent HPLC verification. Read our philosophy, methods and standards below.

§04 — Philosophy

The Masterof Peptides.

· Since 2021 · Atelier Netherlands

We believe that science is a craft. Every vial is treated as a small object of precision — produced in a controlled environment, tested by independent laboratories and sealed until the moment of research.

I.
Purity above all

Every batch undergoes HPLC analysis. No compromise on the purity or identity of the peptide.

II.
Independent control

Endotoxins and heavy metals are tested by third parties. COA available on request.

III.
Discreet and meticulous

Lyophilised, sealed, shipped cool. From atelier to laboratory.

Testing methods

Every batch, four tests.

HPLC ≥ 99%

Reverse-phase HPLC on every batch. Chromatogram archived per lot and matched against the reference peptide.

Endotoxin (LAL)

Limulus Amebocyte Lysate assay confirms endotoxin levels well below research thresholds.

ICP-MS

Trace metals — arsenic, cadmium, lead, mercury — measured by ICP-MS. Report on request.

Argon-seal

Vials lyophilised and sealed under argon inert atmosphere. Cold-chain shipped from atelier.
