someone explain bacteriostatic water to me like I have not read a paper in years
Trying to settle this properly because the thread from last year went in circles.
The claim: reconstitution matters. The counter-claim: it is measurement error. Both sides have been asserting it confidently for about 11 months without either producing anything.
What would actually settle it is 11 people measuring the same thing the same way. I have started; my numbers are below. They lean one way but not strongly enough for me to declare victory.
If you have data, post the data. If you have an opinion, flair it as an opinion.
best — the order this archive was captured in
No. This is the kind of confident post that gets copied into a screenshot and repeated for years. Where is the evidence.
i am begging people to write down the concentration
Did you write the concentration on the vial?
more water means more units for the same dose, which means finer resolution

This is correct. 2mL versus 13mL is the common mistake.
show your working or it is unhelpful
Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.
dosing errors come from people reconstituting two vials differently and forgetting which is which
This is the "correlation is mechanism" thing again. You changed three variables at once.
This is correct. 3mL versus 2mL is the common mistake.
This is correct. 1mL versus 9mL is the common mistake.
5mg vial, 1mL water, concentration is 5/1 — write it on the vial afterwards
swirl, do not shake, or you are courting oxidation

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

Cored the stopper on my 18th draw because I kept using the same entry point. Rotate the puncture site.
never post a calculation as advice without stating the concentration

Cosigning. The concentration on the vial in marker is load-bearing.
Are you using a u-100 or u-40 syringe? That changes everything.

Yes, exactly this, and it is the bit that took me 6 weeks to accept.

Removed a chain here. The rule is one line long and it is not negotiable.
