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.
§ Atelier · Anatomy
What your order looks like
Four elements you'll find on every vial or pen we ship — clean labeling, secure sealing, batch traceability and discreet delivery.
2
Seal
Sealed stopper
Black rubber stopper with aluminum crimp — vacuum sealed and untouched on arrival.
3
Traceability
Batch controlled
Every batch independently tested. On request we email the matching Certificate of Analysis (COA).
4
Shipping
Discreet & cooled
Anonymous packaging, cooled where needed, and SEPA Instant payment so we can ship immediately after ordering.
§07 — The atelier in numbers
Numbers weshare with pride.
Four numbers that summarise our atelier. Every vial we ship must meet these standards — otherwise it goes back to the lab.
