A certificate of analysis (COA) is the lab report for a specific batch. It documents the identity and purity results from independent testing so you can review them yourself.
Where to find COAs
- Product page. Each product page links to the COA for the current lot.
- COA Library. Browse published certificates by product at protidehealth.com/coa-library.
The COA landing page
Every COA has its own dedicated landing page. On that page you can:
- See the full breakdown of the test results for that lot
- Download the COA as a PDF
- Scroll to the bottom to see previous COAs for the same compound, listed in chronological order
Older certificates are also collected in the COA archive.
Matching a COA to your vial
Each vial label carries a lot number. Match that lot number to the certificate on the COA landing page to see the results for the exact batch you received.
What the COA shows
- The compound name and lot number
- Identity confirmation by mass spectrometry (LC-MS)
- Purity by high-performance liquid chromatography (HPLC-UV), reported as a percentage
- Net peptide content, quantified so you know exactly what is in the vial
- Additional testing completed for that batch, where applicable (see below)
- The testing laboratory and test date
The 7-test panel on new batches
New batches now run a full 7-test panel. In addition to identity, purity, and net peptide content, the panel includes:
- Bacterial endotoxin (LAL, in line with USP <85>)
- PCR microbial screening
- ICP-MS heavy metals testing for arsenic, cadmium, lead, and mercury
- Fentanyl screening
Only batches that meet our purity threshold are released. Older lots tested before the expanded panel show the original three tests on their COA.
