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.

Saving this. It is the first explanation that did not require me to already understand it. Sending this to two other people who asked me the same thing last week.

Ongoing cost tracking for dosing arithmetic — transparency for the community:
Monthly medication cost: $144
Supplies (syringes, BAC water, alcohol swabs): ~$12/month
Janoshik testing: ~$14/month (amortized quarterly)
Lab work: ~$54/month (amortized quarterly)
Total: ~$214/month
Compare to brand Wegovy at $1334/month without insurance. Compounded is roughly 85% cheaper for what I have found to be clinically equivalent medication.
