Purity, Verified
Every vial is traceable to a tested batch
We ask you not to take our word for it. This page explains exactly how each batch is tested, what the accompanying Certificate of Analysis records, and how to obtain the certificate for a vial you already hold.
01
Batch is sampled at fill
Every production batch is sampled before release. Nothing ships from an untested lot.
02
Independent laboratory analysis
Samples are analysed by accredited ISO 17025 laboratories — HPLC for purity, LC-MS for molecular mass confirmation, plus endotoxin and sterility screening.
03
Certificate of Analysis issued
The laboratory issues a batch-specific Certificate of Analysis recording the purity result, the chromatogram and the test dates.
04
COA travels with your vial
Your order ships with the Certificate of Analysis for the exact batch number printed on the vial you receive.
Requesting a certificate
The Certificate of Analysis for your batch ships with your order. If you need another copy — or you want to review a batch before ordering — send us the batch number printed on the vial label and we will return the certificate for that lot.
Our searchable archive of released batches is being populated; until every lot is loaded, certificates are issued on request.
