Blind purchase

Buying a product anonymously on the open market, with no vendor involvement and no advance notice. The vendor does not know a sample is being pulled, so they cannot select which unit we receive.

Chain of custody

The documented, photographed record of a sample from the moment it arrives to the moment it is handed to the laboratory, including temperature readings at receipt, in storage, and at open.

Quality grade

A 0-to-100 score with a letter, always shown together as for example “A · 93”. It measures purity and dose accuracy only. Identity, safety, and COA integrity are reported separately and never folded into it.

Grade suppression

When identity is not confirmed, no grade is published at all: no letter and no number. A vial that is not the labeled compound has nothing coherent to grade, so the measurements are published as raw values instead.

Identity gate

Identity is checked before anything else, and it decides whether a grade appears. It is not scored, because a compound either is or is not what the label says.

COA Integrity flag

A separate finding comparing a vendor’s own certificate against our independent result. Reported beside the grade, never inside it.

Safety-tested denominator

Safety assays are not run on every sample, so safety failures are counted against the number of samples actually tested for safety, not against the total. That is why a vendor page can show a different count for quality and for safety.

Graded sample

A sample that received a quality grade. Samples that failed identity are excluded from this count, because they were never gradeable.

Publish-fails policy

We publish every result we commission, including the poor ones. A tester who only publishes good news is running a marketing program.

Never-revise

We do not retest a failing result at a vendor’s request, and we do not quietly amend a published report. Retests happen at our discretion and the original result stays on the record.
