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.

Second this.

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

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.
A narrower follow-up, since the general answer is now clear:
What did you change at the same time, and can you separate the two now?
