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 answered a question I did not know how to ask. Printing the relevant bit and taking it with me.

Bacteriostatic water quality matters for dosing arithmetic reconstitution. Not all BAC water is created equal:
- Should contain 0.9% benzyl alcohol as preservative
- Must be sterile and pyrogen-free
- Should come in a sealed, intact vial
- Check expiration date — yes, BAC water expires
- Store at room temperature, protected from light
I buy from a reputable medical supply company, not Amazon marketplace sellers. The $3 savings isn't worth the infection risk from unverified BAC water.

Peptide calculator app recommendation for dosing arithmetic: I use ReconCalc 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.
