how much of what we believe about purity actually comes from PeptideMeter threads

Below Spec Long Haul ×7 Slow Clap ×2 Cold Box ×3

how much of what we believe about purity actually comes from PeptideMeter threads — that is what I am asking, and I have already read the wiki twice.

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

Have now spent more on testing than on some of the orders. No regrets — the log is the reason I can buy without agonising.

Sent a vial in specifically to check a supplier’s claim after a good experience. It matched. Boring result, worth logging.

Sceptical readings welcome. The confident ones are the ones I distrust.

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.

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.

Yes. Two services on the same batch is the strongest thing an individual member can produce, and it is not expensive.

A series across separate lots estimates a process. Repeat tests on one lot estimate the measurement. Both are useful and they answer different questions.

Did the vial lot match the paperwork lot?
