[Question] mg/mL — what am I missing here
Right, the mg/mL question again, but with numbers this time.
I have 13 data points over 34 weeks. The pattern is consistent enough that I do not think it is chance, and boring enough that nobody is going to screenshot it, which is usually a good sign.
The thing I would flag for anyone new: the effect I am describing showed up at week 88, not week 42. People give up long before the interesting part.
Interested in whether this matches other people's logs or whether I am an outlier.
best — the order this archive was captured in
dead space is real and the syringe matters
This is correct. 2mL versus 6mL is the common mistake.
Disagree but this is the good kind of wrong — it is specific enough to be checked.
Reconstituted at 3mL when I meant 3mL. Caught it because the units looked wrong. Write the concentration.

What was the vial size and how much bac water?
u-100 syringe, not u-40, or your math is off by factor of 15

Reconstituted at 2mL when I meant 7mL. Caught it because the units looked wrong. Write the concentration.

Disagree on that part. 97.9% and 97.6% on the same vial is normal.

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.
dosing errors come from people reconstituting two vials differently and forgetting which is which
Show the arithmetic. Where did the units come from?
No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.
Yeah, showing the arithmetic is the fastest way for someone to spot the error.
Cored the stopper on my 16th draw because I kept using the same entry point. Rotate the puncture site.
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

the concentration on the vial in marker is the most important step
Water content matters more than people think. If a vial is carrying residual moisture, your "10mg" is not 10mg of peptide.
never post a calculation as advice without stating the concentration
