How we test it

Every level includes purity, quantity, identity and a solubility check. Pick the level that matches what you need to know.

$250

Purity and quantity by reversed-phase HPLC with the detector matched to the compound, identity against a reference standard, solubility check. 1 vial.

$550

Silver plus endotoxin (USP 85) and sterility (USP 71). 3 vials.

$700

Gold plus heavy metals by ICP-MS and a fentanyl screen. 4 vials.

Turnaround and reporting

Purity, quantity and identity are reported in 3 to 5 business days after the samples are logged in. Sterility adds a 14-day incubation, and you get a preliminary COA while it runs. The COA carries a QR code that opens the current version of the report on verifiedbyvanguard.com.
