Been lurking a while, first time posting.
Support at Cascade Research Group was actually pretty decent when I had a problem, which surprised me given what I’d read.
Worth noting there’s an Index Score of 35 for them published, which is more than I expected honestly.
Not looking for anything other than what people have actually run into.

Respectfully I think you are reading more into that result than it supports.
Reversed-phase HPLC with UV detection at 214nm is the standard here because the peptide bond absorbs there. If a vendor reports purity without stating the method or wavelength, the number is not comparable to anything.
Agreed.

Who funded the study though. That is usually the first thing worth checking and almost nobody does.
