COA Library

Every compound we sell is tested by an independent third-party laboratory before it's listed — not just once, but per batch. Below is the current reference list for our catalog.

How We Test

Our primary testing partner is Janoshik Labs, an independent laboratory specializing in HPLC purity analysis for peptides and research compounds. Each batch we bring in is assigned its own Janoshik task number and batch code, which is published directly on that product's page alongside the purity result — so what you see is tied to the specific material you're ordering, not a generic claim.

A Note on HCG and HMG
These two products are currently sold to manufacturer specification while their independent Janoshik Labs verification is in progress. We'll update this table as soon as those results are in — we'd rather tell you a COA is pending than leave you guessing.

This table shows the headline purity result for each batch. If you'd like the complete Janoshik Labs report — including the full HPLC chromatogram — for the batch you received, email us at support@peptonia.com with your order number and we'll send it over.
