dosing errors come from people reconstituting two vials differently and forgetting which is which

Hard agree. Week 40 me needed this. Week 89 me is nodding smugly.

redact your own name, not the vendor's batch details

never post a calculation as advice without stating the concentration

This is what I tell everyone in c/newbiequestions and they never believe me until week 52.

the 2.4mg dose is not the target, it is just what the pen goes up to

What was the method? "HPLC" is a technique, not a method.

Disagree. What you are describing is consistent with insulin syringe, not with what you concluded.

This is an urgent-care question wearing a forum question's clothes.

Disagree on that part. 99.0% and 98.9% on the same vial is normal.

pens are overpriced, research vials are research grade, same molecule different price

axis labels included, always

This matches my experience almost exactly on the Ozempic pens. The titration is the whole point.

bacteriostatic and sterile water are not interchangeable, do not use them that way

Mechanistically the bit that matters is titration. It explains most of the early profile and a decent chunk of the outcome.

Tested the GLB raw material and a reseller vial side-by-side. Same purity claim, different impurity profiles. Handling matters.

Two vials, two different concentrations, forgot which was which, almost made a 13 times error. Now I label everything.

Small correction: the trial was 3 weeks, not 14.

Disagree on that part. 93.7% and 99.3% on the same vial is normal.
