How it works
Step 1
A vial is bought or sent in
For the Index, Tested.ph buys vials anonymously through each vendor's normal checkout, like any customer. Buyers and vendors can also send a vial in for their own record.
Step 2
The label is photographed and coded
The sealed vial is photographed, the label is covered, and the vial gets a sample code. The partner lab never sees the vendor's name.
Step 3
A partner lab runs the analysis
Identity by mass spectrometry, purity by HPLC, and the amount in the vial against a reference standard. Endotoxin is an optional extra.
Step 4
The report is signed and fingerprinted
The lab's registered chemist signs the report. Tested.ph stores the PDF, records its SHA-256 fingerprint, and gives the vendor 72 hours to reply before publication.
Step 5
The record goes public
Every record gets a task number and a key. Anyone holding them can check the result on tested.ph, and the record cannot be quietly edited: corrections are logged in public.
Transcript
How Tested.ph works. Five steps from a vial on a shelf to a record anyone can check. One. A vial is bought anonymously, or sent in by a buyer or a vendor. Two. The label is photographed, covered and replaced with a sample code. Three. A partner lab tests identity, purity and the amount in the vial. Four. The chemist signs the report. Its fingerprint is recorded, and the vendor can reply. Five. The record goes public with a task number and a key. Verify any record at tested.ph.
What keeps it honest
- Anonymous buying. Index vials are bought through normal checkouts, so vendors cannot pick which vial gets tested.
- Blind analysis. The lab sees a sample code, not a vendor name.
- Fingerprinted reports. The SHA-256 hash of each signed PDF is published, so any copy can be checked against the original.
- Right of reply. Vendors get 72 hours before publication, and replies are published unedited.
- Public corrections. If a record changes, the change is logged on the record and in the corrections log.
