Feature request: should a dose-equivalence tool exist at all?

Feature request: should a dose-equivalence tool exist at all? — that is the question, and I have not found it answered plainly anywhere I have looked.

Posting the method first, because I know what the first three replies will otherwise be.

• Column: C18, 2.1 x 100 mm, 1.7 um
• Mobile phase: 0.1% TFA in water / 0.1% TFA in acetonitrile
• Gradient: 12% to 70% organic over 21 minutes
• Detection: 214 nm
• Injection: 6 uL
• Sample: semaglutide, reconstituted to 2.0 mg/mL, injected within an hour

The main peak integrates at 96.1% of total area. There is a small feature on the trailing edge that I cannot decide is a shoulder or a baseline artefact, and that is what I am actually asking about.

Worth separating two things that post #2 runs together.

Why calculators are not medical advice: they do arithmetic. Medical decisions are not arithmetic. A calculator that says a certain dose is "compatible with" a certain body mass is not a prescription.

This follows post #13 rather than contradicting it.

Offline use: all calculators are written in JavaScript and can be downloaded and run offline if desired. They do not require internet connectivity to function.

Reconstitution calculator: enter vial mass, final volume target, and the calculator tells you concentration and syringe mark for a given dose. Useful for double-checking arithmetic when you are doing it by hand.

On post #20 — agreed on the reasoning, with one qualification.

Practical note that does not fit anywhere else. Whatever you conclude from this topic, write down what you did and when. The single most useful thing in your own records is not any individual result; it is that they are dated and consecutive.
