Peptide reconstitution, made easy to verify.
Enter the vial amount, how much diluent you added, and your target dose. You’ll get the exact concentration, the draw volume in mL, and the matching U-100 syringe units, with live interpretation so the math is easier to trust.
Step 1
Set your vial and diluent
Use presets or type the exact values from your label and mixing plan.
Step 2
Choose the target dose
Dose is entered in mcg, which is how many protocols are written.
Step 3
Cross-check the draw
See mL, units, and what each syringe mark means at your dilution.
Calculator
Live dose conversion
All outputs update instantly. This calculator assumes a U-100 insulin syringe for unit conversion.
If instructions do not match, stop and confirm.
Common vial setups
Tap a preset, then fine-tune if needed.
Quick doses
Dose stays in mcg, then converts to mg behind the scenes so the formula is easy to audit.
Syringe type
Unit conversion below is only valid for U-100 syringes.
Concentration
—
mg per mL after mixing
Volume to draw
—
mL for your target dose
U-100 units
—
units on the syringe
Interpretation
Enter values to generate a clear draw summary.
We’ll also show how much peptide each syringe unit represents at this dilution.
Rounding check
Useful when your syringe only marks whole units.
Exact values are shown above. Round only if your syringe markings require it.
How the formula is behaving
These cues help spot awkward dilutions before you draw.
Per unit
—
mcg in each U-100 unit
Per 10 units
—
mcg in 0.10 mL
Approx doses / vial
—
at this target dose
Quick reference
- 100 units = 1.00 mL
- 10 units = 0.10 mL
- 5 units = 0.05 mL
- 1 unit = 0.01 mL
How the math works
Simple enough to audit by hand
The calculator is deliberately transparent. You can check each step with a basic calculator if you want a second confirmation.
1. Concentration
vial mg ÷ diluent mL
Example: 5 mg ÷ 2 mL = 2.5 mg/mL.
2. Dose in mg
dose mcg ÷ 1,000
Example: 250 mcg = 0.25 mg.
3. Draw volume
dose mg ÷ mg per mL
Then multiply mL by 100 for U-100 units.
FAQ
What syringe does this assume? ▾
U-100 insulin syringes only. On U-100, 100 units equals 1 mL. If your syringe is U-40 or something else, rely on the mL result unless a clinician or pharmacist confirms the conversion.
Why do different dilution examples exist online? ▾
Because the best dilution depends on the vial size, the dose range you need, and how easy you want the syringe marks to be to read. This calculator does not prescribe a dilution, it simply makes the math explicit.
Is this medical advice? ▾
No. This is educational only. It cannot verify your medication, vial labeling, prescription, or your syringe. Follow your clinician or pharmacist instructions and stop if anything does not match the label in front of you.
