you did do it though. you checked, found you were wrong, and said so at the top of the thread instead of quietly in a reply. that is the whole procedure working.
and QYB answered a hostile question with the document instead of a lawyer, which is its own data point in their favour.
they did the same for me on a custom peptide — sequence and theoretical mass, unprompted. the technical side of that company is genuinely responsive.
2008 entity, verified, custom synthesis capability corroborated by two members with written quotes. the record has been quiet for three years.
