Tested before it ships.
Every batch is verified, sterile-filled, and matched to its own certificate of analysis. Here is how that works, and how to read the certificate yourself.
How every batch is verified.
Each batch runs through the same checks before it reaches a vial. We do not ship a batch until it clears.
- HPLC (High-Performance Liquid Chromatography) measures purity and confirms the compound is what the label says.
- Mass spectrometry (MS) confirms the molecular identity of the compound.
- Testing is run by an independent, accredited third-party laboratory.
- The batch is sterile-filled.
What a COA shows.
A certificate of analysis (COA) is the lab report for a specific batch. Every batch has its own COA, and we post it on the product page. Here is what each part means.
- Identity. Confirms the vial holds the exact compound on the label, verified by mass spectrometry.
- Purity percentage. The share of the sample that is the target compound, measured by HPLC. Our standard is 98%+.
- Endotoxin. A check for bacterial endotoxin, reported against the accepted limit.
- Heavy metals. A screen for trace metal contamination such as lead, arsenic, and mercury.
How to read a COA.
Match the batch number on your vial to the batch number on the certificate. They should be identical. From there, read down the report.
- Check the compound name and batch number against the vial label.
- Read the purity percentage. Ours meets or beats 98%.
- Confirm the identity result matches the compound you ordered.
- Review the endotoxin and heavy-metals results against the reported limits.
- Note the test date and the laboratory that ran it.
Find the COA for your batch.
Each batch carries a scannable QR code. Scan it and you land on the certificate of analysis for that exact batch. No guessing, no shared certificates standing in for a whole product line. The certificate for a given compound lives in the details section of its product page, and we will send a copy on request for any batch you have ordered.
The honest difference
Disclosed methods, per-batch certificates.
We tell you how the material is tested and we give every batch its own certificate. You are not trusting a claim, you are reading a report tied to the vial in your hand.
