Just received my dosing arithmetic order — packaging review:
- Outer box: plain brown, no medication identifiers (discreet) ✅
- Inner insulation: Styrofoam with 3 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.

Thank you for spelling out the reasoning rather than just the conclusion. Adding it to my notes with a link back to this thread.
Clinical perspective, offered as context rather than as advice.
Compounding pharmacy dose accuracy check for dosing arithmetic: I always verify my first dose from a new vial by weighing it on a milligram scale. Draw up your dose, weigh the syringe, subtract empty syringe weight, compare to expected water weight at that volume.
For a 10-unit dose (0.1mL): expected weight ~100mg of water. If it's significantly off, your syringe may be inaccurate. Cheap insulin syringes can have ±5% volume accuracy. Spring for quality brands like BD or Terumo.

Second this.
OP back with an update, since a thread like this is useless without one.
Late follow-up. I did not do what was suggested, I did something adjacent, and it worked; posting the difference in case it matters to somebody.
