Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

no question too basic, read the wiki first, then ask anyway

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

Disagree on that part. 95.1% and 99.3% on the same vial is normal.

the method line is doing real work, not just window dressing

This is the correct framing.

Adding to this: area percent is doing more work than the comment implies.

That is net peptide content, not purity. Different number, different meaning.

Three years on this site and the questions have not changed at all. Which is depressing or reassuring depending on the day.

Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.

the 15mg is the top of the pen, not the required dose

Disagree. What you are describing is consistent with related substances, not with what you concluded.

Not to be pedantic but tirzepatide and Mounjaro are being used interchangeably and they are not interchangeable in real life.

the appetite change on tirz is more than just reduced hunger, it is different machinery

is this normal week 23 — yes, probably

This is the correct framing. The COA structure matters as much as the number.

the 15mg is the top of the pen, not the required dose

Yeah, 96.8% area is not the problem, the missing impurity breakdown is the problem.

stalled on sema, tried tirz, and the curves were actually different shapes

What was the batch number and which service?

the dual agonism hits different and that is why people describe it differently
