PS / Science
A purity protocol you can quote in a chart note.
Every lot we ship is tested for HPLC purity, bacterial endotoxin, and identity by mass spectrometry. The certificates live in your account, not in a sales-rep email.
Identity & purity
HPLC + mass-spec on every batch.
Reverse-phase HPLC is run on every batch and reported as a percentage with two decimals alongside the mass-spectrometry confirmation. We publish the actual numbers — not a rounded ≥99% claim with no detail behind it.

Lot traceability
The vial label, the order record, and the COA all carry the same lot number.
When you receive a Purity Science order, the lot stamped on the vial maps back to a batch record in your portal. Pull up any past order and the same lot, COA, and shipping documentation are one click away — for every dose you've ever administered.
That same trail flows into your records, so when a regulator asks how you sourced an ingredient, the answer is on a single screen.
Cold-chain handling
Packed, tendered, and tracked end-to-end.
Vials ship from a temperature-controlled facility in the United States, packaged with phase-change materials sized to the destination ZIP. Tracking numbers post automatically to the order detail page; deliveries to restricted states are blocked at checkout, not discovered in transit.
