Bacteriostatic water quality matters for dosing arithmetic reconstitution.

Ongoing cost tracking for dosing arithmetic — transparency for the community:

Monthly medication cost: $117
Supplies (syringes, BAC water, alcohol swabs): ~$10/month
Janoshik testing: ~$12/month (amortized quarterly)
Lab work: ~$47/month (amortized quarterly)
Total: ~$187/month

Compare to brand Wegovy at $1207/month without insurance. Compounded is roughly 88% cheaper for what I have found to be clinically equivalent medication.

The arithmetic is right and one caveat matters: a U-40 syringe changes the markings, not the volumes.

Thank you for spelling out the reasoning rather than just the conclusion. Sending this to two other people who asked me the same thing last week.

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.

I reconstituted a 10mg vial with 2ml of bacteriostatic water and I want someone to check my unit arithmetic before I draw anything, because I keep…

Comparison of compounded dosing arithmetic delivery formats I've tried:

I use lyophilized vials for cost and stability. The reconstitution takes 30 seconds once you've done it a few times.
