I am going to disagree with reconstituting low as a general rule. More diluent, more punctures, more in-use days at room temperature, and the stability trade-off is real. Precision is not the only variable being optimised.
Ask again with the specifics and you will get a better answer than this one.

Comparison of compounded dosing arithmetic delivery formats I've tried:
| Format | Pros | Cons |
|---|---|---|
| Lyophilized vial | Longest shelf life, lowest cost | Requires reconstitution |
| Pre-mixed vial | Ready to draw up | Shorter shelf life (28-45 days) |
| Pre-filled syringes | Most convenient | Higher cost, shorter shelf life |
| Sublingual drops | No needles | Lower bioavailability, less data |
I use lyophilized vials for cost and stability. The reconstitution takes 30 seconds once you've done it a few times.

Sharing my dosing arithmetic titration experience with compounded semaglutide — I have been tracking injection volumes meticulously:
Using 5mg/2mL concentration with 1cc insulin syringes:
The beauty of compounded vials is you can do custom intermediate doses. My provider was great about tailoring to my response.
Certified reference materials, analytical reagents, and research-grade standards for peptide verification. Trusted by laboratories worldwide.

Reporting back.
My error was treating units as a mass. Once I wrote mg/ml on the vial in marker and worked in millilitres first, the two of us got the same answer.
