Peptide calculator app recommendation for dosing arithmetic: I use PeptideCalc to calculate reconstitution volumes and injection doses. Eliminates math errors completely.
Input: vial size (mg), desired concentration (mg/mL), prescribed dose (mg)
Output: BAC water volume (mL), injection volume (units on insulin syringe)
A math error with injectable medication can mean underdosing or overdosing. Use a calculator every time until the math becomes second nature.

Thank you — that is the clearest version of this I have read, and I have read a lot of them. I will report back once I have actually tried it.

Ongoing cost tracking for dosing arithmetic — transparency for the community:
Monthly medication cost: $124
Supplies (syringes, BAC water, alcohol swabs): ~$12/month
Janoshik testing: ~$14/month (amortized quarterly)
Lab work: ~$54/month (amortized quarterly)
Total: ~$224/month
Compare to brand Wegovy at $1314/month without insurance. Compounded is roughly 88% cheaper for what I have found to be clinically equivalent medication.

Quick syringe math for dosing arithmetic dosing: if your vial is reconstituted at 5mg/2mL, that's 2.5mg/mL. For a 0.25mg dose you need 0.1mL = 10 units on an insulin syringe.
I keep a chart on my fridge:
- 0.25mg = 10 units
- 0.5mg = 20 units
- 1.0mg = 40 units
- 1.25mg = 50 units
Always double-check your concentration before drawing up!
