Ongoing cost tracking for dosing arithmetic — transparency for the community:
Monthly medication cost: $150
Supplies (syringes, BAC water, alcohol swabs): ~$8/month
Janoshik testing: ~$10/month (amortized quarterly)
Lab work: ~$50/month (amortized quarterly)
Total: ~$230/month
Compare to brand Wegovy at $1390/month without insurance. Compounded is roughly 85% cheaper for what I have found to be clinically equivalent medication.
Following on from KevinCompounds — and this may be the naive question:
How to check the arithmetic without trusting a website calculator, since three calculators gave me three answers?

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.

Follow-up: it was dead space. Switching to a low-dead-space fixed-needle syringe gave me the tenth dose back.

Agreeing with jim_asheville, and the qualification matters more than the agreement. The arithmetic is right and one caveat matters: a U-40 syringe changes the markings, not the volumes. If someone hands you U-40 and you read it as U-100 you will be 2.5 times out, and that error has a direction — it is always an overdose.
