From the other side of the consultation, briefly.
Bacteriostatic water quality matters for dosing arithmetic reconstitution. Not all BAC water is created equal:
- Should contain 0.9% benzyl alcohol as preservative
- Must be sterile and pyrogen-free
- Should come in a sealed, intact vial
- Check expiration date — yes, BAC water expires
- Store at room temperature, protected from light
I buy from a reputable medical supply company, not Amazon marketplace sellers. The $3 savings isn't worth the infection risk from unverified BAC water.

This matches mine closely enough to be worth saying so out loud.

Reconstitution tip for anyone mixing dosing arithmetic from lyophilized powder: use bacteriostatic water, NOT sterile water. The benzyl alcohol in BAC water preserves multi-dose vials for up to 28 days.
Inject the water slowly down the side of the vial. NEVER shake — gentle swirling only until fully dissolved. Should be crystal clear with no particles.

Peptide calculator app recommendation for dosing arithmetic: I use PeptideCalc to calculate reconstitution volumes and injection doses. Eliminates math errors completely.
Input: vial size (mg), desired concentration (mg/mL), prescribed dose (mg)
Output: BAC water volume (mL), injection volume (units on insulin syringe)
A math error with injectable medication can mean underdosing or overdosing. Use a calculator every time until the math becomes second nature.
A narrower follow-up, since the general answer is now clear:
Did your prescriber agree with that reading, and if not what was their objection?
