[Question] concentration — what am I missing here
Genuinely asking, not being difficult.
Everyone in c/orforglipron repeats that concentration is important. I believe it, but I have never seen anyone show why, and when I search I get 20 threads of people agreeing with each other.
Is there a paper? Is there a measurement? Or is this one of those things that is true because it has been repeated since 2023?
I am not trying to be the "source?" guy. I would just like a source.
best — the order this archive was captured in
i am begging people to write down the concentration

Disagree on that part. 97.6% and 97.9% on the same vial is normal.
15mg vial, 2mL water, concentration is 15/2 — write it on the vial afterwards
Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.
dead space is real and the syringe matters
Spent 4 weeks confused about concentration math until someone showed me the table. 20mg, 2mL, concentration is 20/2.
5mg vial, 2mL water, concentration is 5/2 — write it on the vial afterwards
You have restated the marketing copy. What is the actual substance here.
never post a calculation as advice without stating the concentration
Did you write the concentration on the vial?
Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.
u-100 syringe, not u-40, or your math is off by factor of 19
dosing errors come from people reconstituting two vials differently and forgetting which is which
