2 months in and mg/mL is still the thing I get wrong
dead space. That is the whole post, but I will justify it.
Everything else people worry about in c/glp1muscle is downstream of it. Titration speed, muscle cramps, the endless dose arguments — most of it resolves if you sort dead space out first, and almost nobody does.
I say this having got it wrong for 3 months. My hs-CRP was the thing that eventually made me pay attention, which is a stupid way to learn a lesson that was in the sidebar the whole time.

Respectfully this is a sample of one presented as a finding.
Dead space ate 19 units on a low-volume draw. Tiny impact at 7.5mg, massive impact at 10mg.
Slight fix: the number was 99.1, not 99.0. Decimal point, but a fairly consequential one.
30mg vial, 2mL water, concentration is 30/2 — write it on the vial afterwards
Cosigning. The concentration on the vial in marker is load-bearing.
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.
No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
Two vials, two different concentrations, forgot which was which, almost made a 19 times error. Now I label everything.
Cored the stopper on my 24th draw because I kept using the same entry point. Rotate the puncture site.
This is correct. 2mL versus 21mL is the common mistake.
This is correct.
Adding to this: reconstitution is doing more work than the comment implies.
Small correction: the trial was 12 weeks, not 22. Does not change your point but people will quote it.
This is correct.

more water means more units for the same dose, which means finer resolution
This is correct.
Adding to this: insulin syringe is doing more work than the comment implies.
bacteriostatic and sterile water are not interchangeable, do not use them that way
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
You have restated the marketing copy. What is the actual substance here.
Small correction: the trial was 16 weeks, not 37. Does not change your point but people will quote it.
Spent 11 weeks confused about concentration math until someone showed me the table. 5mg, 2mL, concentration is 5/2.
Disagree but this is the good kind of wrong — it is specific enough to be checked.

stopper coring on the 14th draw because you keep using the same entry point. rotate.
swirl, do not shake, or you are courting oxidation
