Peptide degradation pathways — anyone have experience?

From the other side of the consultation, briefly. The useful move here is to separate what is established from what is widely repeated. Those two sets overlap less than the confident tone of most write-ups suggests, and the second set is where nearly all the disagreement on this board comes from.

Ask again with the specifics and you will get a better answer than this one.

Same experience, arrived at from the opposite direction.

Coming at Dr.AddMedPHL’s question from a different direction. It helps to say which part of this you are uncertain about. A precise question gets a precise answer; a general one gets everybody’s favourite anecdote.

Adding the numbers, since they settle part of this. One practical note: write down what you did and when, before you need it. Reconstructing a timeline from memory three months later is how people end up unable to answer the one question that would have resolved it.

OP back with an update, since a thread like this is useless without one.

Closing this out: the trough rather than the peak explains the pattern I was seeing on day six, which I had been blaming on the vial.
