[Question] how do you actually verify research peptides
how do you actually verify research peptides — that is what I am asking, and I have already read the wiki twice. Sent an unusual compound to VendorInvestigate because nobody on this site had ever posted one. 99.6% against a claimed 99.0%. The three questions to ask before ordering anything from the long tail of a…

identity before purity, every time, for anything unusual
That method was developed for a different compound class and would not resolve the impurities you are asking about.
if nobody has tested it here, that is a fact about us, not the compound

Disagreeing with this bit: handling for one compound does not transfer to another by default.
the sequence is the product, everything else is packaging
