Why DryV Tests Every Lot Twice
Published October 15, 2026
Research results are only as reliable as the materials behind them. That is why every DryV lot goes through two separate rounds of testing before we post it.
Step one: the supplier test
Each lot arrives with testing from our supplier. This is the standard most of the market relies on, and it is a useful first check. On its own, though, it means trusting the same party that made the product to grade it.
Step two: an independent retest
We then send samples from the lot to Freedom Diagnostics, an independent US testing lab with no stake in the outcome. They run HPLC with UV detection coupled with mass spectrometry to confirm three things:
- Identity: the vial contains the compound on the label.
- Purity: how much of the sample is that compound.
- Fentanyl screening: as of October 2026, every new lot we send for testing is also screened for fentanyl, and the result is printed on the COA.
Their report also records the net content of the vial and its appearance.
Results matched to your vial
For products sold in more than one size, each size carries its own COA matched to that exact vial SKU. We never use one product's report to stand in for another, and we never post a report from a different size.
Posted for you to check
Every COA we receive is posted publicly on our Lab Results page and linked from the product page. Each report includes a QR code and search code so you can confirm it directly with the lab.
Every report stays on file
We keep up to six past COAs for each product and size, not just the newest one. If you hold on to a vial for months, you can still go to that product's page and find the report for your lot. Each COA includes a photo of the tested vial, so you can match your vial by its cap color.
Products still awaiting their Freedom Diagnostics results are clearly marked, and their COA is added as soon as testing is complete.
