Certificate of Analysis
Identity, purity and potency, verified per batch by an independent laboratory. The certificate is included in the box rather than kept behind a request form, because evidence you cannot see is not really evidence.
The standard
Trust is the product.
Behind every PEPHOUSE pen is a chain of evidence most brands never show you. We treat it as the most important thing in the box.
Cold chain, end to end
Temperature-controlled storage and shipping, monitored from production to your door. What you receive is exactly what was made and tested, with nothing lost in transit.
Lot traceability
Every pen carries a lot number that ties it back to its batch and its paperwork. If a question is ever asked, the answer can always be found.
Considered packaging
Oak, bone and paper, chosen to protect what is inside and to be worth keeping. The care you can hold is a fair signal of the care you cannot see.
Included, not hidden
The certificate comes in the box.
Most brands will send a Certificate of Analysis if you ask, and many quietly hope you will not. We print the relevant batch detail and ship it alongside the pen, so the proof and the product arrive together.
- Independent, third-party laboratory
- Tested per batch, not per brand
- Matched to the lot number on your pen
