Certificate of Analysis
Certificates of Analysis for every batch we release.
Every production run is verified by an independent, ISO/IEC 17025-accredited laboratory before it ships. Search by product name or the lot number printed on your box.
Identity
LC-MS confirmation that the compound is what the label says.
Purity
HPLC-UV analysis of the active against a qualified reference standard.
Uniformity
Per-strip content checked across the batch, 90–110% of label claim.
Safety
Microbial counts and heavy-metal screening on every run.
No products or batches match that search. Try a product name or a lot number like PS-2606-114.
Frequently Asked Questions
What is a Certificate of Analysis?
A COA is a lab-issued document confirming that a specific production batch was tested and meets its specifications — identity, purity, per-strip content, and safety screens. Each COA applies only to the batch listed on it.
Where do I find my batch number?
The lot number is printed on the bottom flap of every box in the format PS-YYMM-NNN. Enter it in the search bar above to jump straight to your COA.
Who performs the testing?
All release testing is performed by an independent, ISO/IEC 17025-accredited laboratory. We do not self-certify results.
How is purity measured?
The active compound is analyzed by HPLC-UV against a qualified reference standard, with identity confirmed by mass spectrometry (LC-MS).
How often are COAs updated?
A new COA is issued for every production run before it ships. If a batch is on this page, it has passed release testing.
My batch isn’t listed — what do I do?
Very recent runs can take a few days to post. Email support with your lot number and we’ll send the COA within one business day.
