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.

This answered a question I did not know how to ask. Adding it to my notes with a link back to this thread.
Clinical perspective, offered as context rather than as advice.
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.

This matches mine closely enough to be worth saying so out loud.

Bacteriostatic water quality matters for dosing arithmetic reconstitution. Not all BAC water is created equal:
- Should contain 0.9% benzyl alcohol as preservative
- Must be sterile and pyrogen-free
- Should come in a sealed, intact vial
- Check expiration date — yes, BAC water expires
- Store at room temperature, protected from light
I buy from a reputable medical supply company, not Amazon marketplace sellers. The $3 savings isn't worth the infection risk from unverified BAC water.
