Quality
Every batch tested twice.
We don’t take a manufacturer’s word for it. Each batch arrives with the manufacturer’s own Certificate of Analysis, and then we send a sample to an independent US-certified laboratory to verify it.
Testing results
Every batch independently tested — open a COA for the full report.

How it works
Manufacturer COA
Every batch ships with a Certificate of Analysis from the manufacturer detailing identity, purity, and any impurities detected during their internal QC.
Independent verification
A sample from each batch is sent to a US-certified analytical lab. They run their own panel and produce a second COA we publish alongside the manufacturer’s.
QR code on the vial
Every vial is labeled with a QR code that links directly to that specific batch’s testing page on this site — both COAs, the batch number, and the manufacture date.

Look for this on the back of every vial.
Where to find a COA
Three ways to access the testing for any product you’ve received from us:
- ·Scan the QR code on your vial — opens the exact batch page for that vial.
- ·Visit the product page — every product lists all batches tested to date, with both COAs for each.
- ·Type the batch URL directly —
