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 is exactly what I could not find anywhere else.

For anyone reconstituting dosing arithmetic peptides: the water-to-powder ratio determines your concentration. Here's my reference:
| Vial Size | BAC Water | Concentration | 0.25mg Dose |
|---|---|---|---|
| 5mg | 2mL | 2.5mg/mL | 10 units |
| 5mg | 2.5mL | 2mg/mL | 12.5 units |
| 10mg | 2mL | 5mg/mL | 5 units |
| 10mg | 3mL | 3.33mg/mL | 7.5 units |
More water = easier to measure small doses but vial runs out faster. Find the balance that works for your dose.

dosing arithmetic — critical reminder about tirzepatide dose equivalence across formulations:
Mounjaro KwikPen and compounded tirzepatide are the same molecule but:
- KwikPen is ready to inject, no mixing needed
- Compounded requires reconstitution and proper syringe technique
- Verify your compounded concentration before each injection
- Never assume 1 vial = 1 dose without checking the math
