genuine question about bacteriostatic water that I am slightly embarrassed to ask
Quick one. Canada here.
reconstitution works very differently where I live than in the threads that dominate the front page, and I keep seeing people confidently given advice that simply does not apply outside the US.
Specifics: the route I used took 16 weeks and cost roughly what I expected. The admin was worse than the cost. The thing that would have saved me the most time was knowing which document to ask for at the start.
Happy to answer questions from anyone in the same jurisdiction.
best — the order this archive was captured in
dosing errors come from people reconstituting two vials differently and forgetting which is which
What was the vial size and how much bac water?
u-100 syringe, not u-40, or your math is off by factor of 11
Reconstituted at 3mL when I meant 9mL. Caught it because the units looked wrong. Write the concentration.
I am going to push back on this slightly.
more water means more units for the same dose, which means finer resolution
more water means more units for the same dose, which means finer resolution
Adding to this: reconstitution is doing more work than the comment implies.
swirl, do not shake, or you are courting oxidation
Reconstituted at 2mL when I meant 14mL. Caught it because the units looked wrong. Write the concentration.
Not to be pedantic but bacteriostatic water and reconstitution are being used interchangeably and they are not interchangeable in real life.
Half-life is about 168 hours, so steady state lands around week 16–5. Practical consequence: what you feel in week 1 is not what that dose does.
10mg vial, 2mL water, concentration is 10/2 — write it on the vial afterwards
the concentration on the vial in marker is the most important step
Are you using a u-100 or u-40 syringe? That changes everything.
dead space is real and the syringe matters
Disagree. What you are describing is consistent with mg/mL, not with what you concluded.
Slight fix: the number was 99.1, not 98.4. Decimal point, but a fairly consequential one.
The single most useful thing I did was write the concentration on the vial. Stopped all the confusion after that.
Slight fix: the number was 98.9, not 99.0. Decimal point, but a fairly consequential one.
Show the arithmetic. Where did the units come from?
u-100 syringe, not u-40, or your math is off by factor of 7
more water means more units for the same dose, which means finer resolution
bacteriostatic and sterile water are not interchangeable, do not use them that way
Cosigning. The concentration on the vial in marker is load-bearing.
Cored the stopper on my 18th draw because I kept using the same entry point. Rotate the puncture site.
Removed a chain here. The rule is one line long and it is not negotiable.
