[Meta] proposal — a flair for water content posts
proposal — a flair for water content posts. Nothing about this affects the ranking maths, before anyone asks. Ask what the stability statement was written against — temperature, light, and whether it was the lyophilised powder or the reconstituted solution. Those are three different claims.

My first certificate had a compound name, a percentage and a logo. I thought that was normal. It is not, and now I know what to ask for.

Disagree on this specific point. Two honest labs can resolve that impurity differently and report different numbers.
the related substances line is where the story is
Sent one vial to PeptideMeter and Medutest. 99.1% and a claimed 99.0%. Cost me more than the vial and I would do it again.
identity and quantity are two questions and most documents answer one
post the whole document, not the headline number
Correction: that is net peptide content, not purity. Different number, different meaning, and the document says so if you read the row label.
Agreed on asking for the storage condition. It is one line and it changes how you read the entire stability claim.
