That reframing is the part I needed. Taking it to my next appointment.
Adding the clinical framing, because it changes how the question reads.
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.

I disagree that testing history is decisive. It tells you what a supplier did when they were being watched. Continuity of behaviour under stress — a late shipment, a failed test, a complaint — is more predictive than any run of good results.

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.
