How we test
Every batch is tested by an outside lab
We don’t grade our own work. An independent laboratory checks each batch, and the report it writes is the one you see.
Tested by an independent lab
Freedom Diagnostics checks each batch for identity and purity. The result is theirs, not ours.
The certificate is on the product page
Open it before you order. Lot number, purity, and net content are on every certificate.
Reviewed before it is vialed
Incoming material is checked for identity and documentation before it goes anywhere near a vial.
Beyond purity
We also screen for heavy metals and endotoxins
A purity number doesn’t tell the whole story. Heavy metals and endotoxins are screened separately, in house, on top of the outside lab’s report.
Heavy-metal screening
ICP-MS catches even trace amounts of heavy metals, down to parts per billion.
Endotoxin screening
Endotoxins are residues left behind by bacteria, and a purity result says nothing about them. Every lot gets its own screen.
Tied to the lot on your vial
Results are tied to the lot number on the vial, so what you read is the batch you received.
