Reconstitution tip for anyone mixing dosing arithmetic from lyophilized powder: use bacteriostatic water, NOT sterile water.

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

Monthly medication cost: $120
Supplies (syringes, BAC water, alcohol swabs): ~$8/month
Janoshik testing: ~$10/month (amortized quarterly)
Lab work: ~$50/month (amortized quarterly)
Total: ~$180/month

Compare to brand Wegovy at $1310/month without insurance. Compounded is roughly 88% cheaper for what I have found to be clinically equivalent medication.

Agreed, and it is worth saying that rounding to the nearest whole unit is usually acceptable at maintenance doses and is not acceptable at the bottom…

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

Just received my dosing arithmetic order — packaging review:

• Outer box: plain brown, no medication identifiers (discreet) ✅
• Inner insulation: Styrofoam with 4 gel ice packs ✅
• Temperature: vials were cold to touch on arrival ✅
• Labeling: lot number, BUD, compound name, concentration ✅
• Included: COA, reconstitution instructions, dosing card ✅

This is what professional compounding pharmacy shipping looks like. If your order arrives without these basics, reconsider your vendor.

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…

Regarding dosing arithmetic multi-dose vial contamination prevention: after reconstituting, I wipe the vial stopper with a fresh alcohol swab before EVERY single draw. I also never touch the stopper with my fingers and use a new needle for each draw.

Even with bacteriostatic water preservative, contamination is cumulative. One sloppy draw can introduce bacteria that multiply over days. Aseptic technique isn't optional — it's essential for injectable medications.

Moderator note: leaving this open. It is being argued well and the disagreement is the useful part.
