Do it in two steps and it stops being confusing.

Thank you for spelling out the reasoning rather than just the conclusion.

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.

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.

Sharing my dosing arithmetic titration experience with compounded semaglutide — I have been tracking injection volumes meticulously:

Using 5mg/2mL concentration with 1cc insulin syringes:

  • Month 1: 10 units (0.25mg) — mild appetite reduction
  • Month 2: 20 units (0.5mg) — significant appetite suppression
  • Month 3: 30 units (0.75mg) — custom intermediate dose
  • Month 4: 40 units (1.0mg) — optimal for me, staying here

The beauty of compounded vials is you can do custom intermediate doses. My provider was great about tailoring to my response.
