Quality Verification & Lab Results.
Every Ronin compound is tested before it ships. This page describes the testing process and how to access the Certificate of Analysis (COA) for the specific batch you received.
Our testing chain.
Each batch arrives with a Certificate of Analysis from Janoshik Analytical, an independent third-party laboratory specializing in peptide purity verification. Janoshik runs both High-Performance Liquid Chromatography (HPLC) for purity quantification and mass spectrometry for molecular-weight identity confirmation on every batch we accept.
Our minimum acceptance threshold is 99.0% purity by HPLC. Batches that do not meet this threshold are rejected and destroyed, and never reach researchers. We do not stock or ship a batch without a current Janoshik COA on file. The COA accompanies the batch from batch intake through to packaging.
Batch tracking.
Every Ronin order is internally linked to its source batch at the moment we package it. We record the batch identifier against your order so we know exactly which Janoshik COA covers the vial you received. Retention samples from each batch are held in our inventory for follow-up testing if a question is later raised about a specific lot.
How to access your batch’s COA.
We do not publish COAs in a public archive. Two reasons: customer order privacy, and to prevent competitor scraping of our batch identifiers. Researchers who want a COA receive it directly, on request, for the batch they actually received.
To request your COA, email support@roninpeptides.ca from the email address you used to place your order. Include your order number and the compound name(s) you would like COAs for. We respond within 24 business hours, typically the same business day.
Each COA carries a Janoshik verification key. You can independently confirm the COA at janoshik.com using that key — the verification step happens between you and the laboratory, with no involvement from us.
What’s on the COA.
A Janoshik COA is a single-page document covering the data fields a researcher needs to confirm batch identity and purity:
- Compound name and lot/batch number.
- Purity percentage by HPLC.
- Mass spectrometry confirmation of molecular weight.
- Test date.
- Janoshik verification key (for independent confirmation at janoshik.com).
Other testing references.
Janoshik Analytical at janoshik.com is an independent third-party peptide testing laboratory used industry-wide. Our internal quality controls run alongside the Janoshik chain: every batch is acceptance-tested at intake, retention samples are kept for follow-up testing, and orders are linked to their source batch in our records. Customer rights under the Returns and Refunds Policy include refund or replacement if a batch is later found to fail purity standards.
