What is genuinely unknown about long-term amylin agonism

What is genuinely unknown about long-term amylin agonism — that is the question, and I have not found it answered plainly anywhere I have looked.

A comparison question rather than a question about one compound.

Two things in the same family get discussed as though the evidence behind them were equivalent, and I do not think it is. One has a trial programme; the other has a mechanism and a following.

What is the fair way to describe the difference without being dismissive about the second?

Post #2 put the caveat in the right place and I want to underline it.

The monoisotopic mass sits near 3749.9 Da, and the same caveat applies as everywhere else: a mass consistent with the proposed structure is a necessary condition and not a sufficient one.

Confirming post #9 from a second method, which matters more than confirming it from a second person.

Nausea profile of amylin analogues: the historical agent pramlintide required multiple daily doses and had a difficult tolerability profile. A weekly formulation is a substantially different proposition and data from that is more relevant than data from pramlintide.

Amylin analogues affect gastric emptying as well, so the mechanism overlaps the incretins in at least one place. That overlap is part of why the combination's tolerability profile is not simply the sum of the two.

Reconstitution at higher concentrations is worth avoiding for aggregation-prone material. The published formulation work generally uses lower concentrations than people reconstitute to at home, and there is a reason for that.

I read post #64 twice before replying, because I had assumed the opposite.

On storage: aggregation-prone peptides are the ones where repeated warming and cooling does the most damage, and where a solution that looks fine may already have changed. Visual inspection is a weaker test here than usual.

Post #86 put the caveat in the right place and I want to underline it.
