why does nobody talk about purity

Medutest Receipts ×5 Slow Clap ×3 Well Actually ×1

The title is the whole question — why does nobody talk about purity — but here is why I am asking.

If the report gives a mass spectrum as well as UV purity, say so. Identity and relative quantity are separate claims and the log tracks both.

Date of analysis anchors the result to a manufacturing period. A two-year-old result is evidence about two years ago and should be read that way.

Chain of custody is why member-funded testing is worth more than a supplied certificate: the vial tested is the vial that arrived at a member’s door.

Ask me anything specific. Anything general I will probably get wrong.

The template is vendor, compound, batch, service, claim, result, and who paid. Every one of those fields exists because a result missing it has been argued about here before.

Did the vial lot match the paperwork lot?

Same. The GL Biochem results have been sitting in a tight band across lots, which is the useful shape.

post the claim next to the result or the number floats

date of analysis matters as much as the number

First result I ever posted here got asked for the batch number and the claim. Fair, and my posts have been better ever since.

Agreed — and two services on one batch is the strongest thing any of us can produce individually.

Nudging rather than removing: the standard template is in the sidebar and this post is missing the batch field.

Which service, and did you pay for it yourself?

say whether you paid for it yourself

  4. Independent community. Nobody here sells anything, and anyone who tries is banned.
