All peptides calculator
Before the math, you should know what AOD-9604 is and isn't. It's a fragment of human growth hormone that was developed as an obesity drug, but development was dropped in 2007 after trial results didn't support it. It has never been approved by the FDA. The FDA lists it among bulk substances nominated for compounding and later withdrawn, citing immunogenicity and impurity concerns (FDA), and it's on the WADA prohibited list.
Much of what's sold online is labelled "for research use only." We don't recommend buying peptides that way. This page doesn't suggest a dose. It only converts an amount you've been given into syringe units, so the number you draw matches the number you intended.
Step 1: Choose your syringe. AOD-9604 amounts are measured in micrograms (mcg), so they usually come out as a small number of units. A 0.3 mL (30 unit) syringe is typically the easiest to read.
Step 2: Enter your vial size in mg. Use the amount printed on the vial. 1 mg is 1,000 mcg, and the calculator handles that conversion for you.
Step 3: Enter the bacteriostatic water you added. More water means a weaker solution and more units for the same amount.
Step 4: Enter the amount in mcg. The presets are shortcuts, not recommendations.
With the defaults shown, a 5 mg vial mixed with 2 mL is 2.5 mg/mL (2500 mcg/mL), so each unit holds 25 mcg and 250 mcg is 10 units. Mix that vial with 1 mL and the same 250 mcg is 5 units.
100 units on a U-100 syringe is always 1 mL. How many micrograms that holds depends on your concentration. This table shows common syringe readings at three concentrations.
The formula behind it is simple: units = amount in mcg ÷ concentration in mcg/mL × 100. The calculator runs that for you, but it's worth knowing so you can sanity-check the result.
For the full mixing process, a vial-by-vial chart, and storage details, see our guide on how to reconstitute AOD-9604. The general peptide calculator covers any other peptide, and PeptideKit can log each dose and remind you when it's time.
Find the concentration by dividing the vial's mcg (mg × 1,000) by the mL of water added. Then divide the amount you need in mcg by that concentration and multiply by 100 for U-100 syringe units. The calculator above does this in one step.
10 units is 0.1 mL. At 2.5 mg/mL that's 250 mcg, and at 5 mg/mL it's 500 mcg. Check the concentration of your own vial first.
It depends on how the vial was mixed. At 2.5 mg/mL, 250 mcg is 10 units. At 5 mg/mL, it's 5 units. The number is only a conversion example, not a suggested dose.
We can't tell you that, and neither can a calculator. AOD-9604 isn't an approved drug, so there's no FDA-reviewed dosing. If you're considering it, speak with a licensed clinician first.
No. It has never been approved by the FDA, and FDA's compounding advisory committee voted against adding it to the 503A bulk substances list in December 2024.

AOD-9604 Dosage Calculator
Enter your AOD-9604 vial size, how much bacteriostatic water was added, and the amount you were told to take in mcg. The calculator shows how many units to draw on a U-100 insulin syringe.
Calculated Dosage
For a dose of 250 mcg, pull the syringe to:
10.0 units
Concentration
2.50 mg/ml
Volume
0.100 ml
Syringe
30 units = 0.3ml
Syringe
Peptide Vial Quantity
5mg
Bacteriostatic Water
2ml
Desired Dose
250 mcg
Use the dose on your prescription. Presets are shortcuts, not recommendations.
How It Works
1. Calculate concentration:
Peptide amount ÷ Water volume = 2.50 mg/ml
Peptide amount ÷ Water volume = 2.50 mg/ml
2. Find required volume:
Target dose ÷ Concentration = 0.100 ml
Target dose ÷ Concentration = 0.100 ml
3. Convert to syringe units:
(Required volume ÷ Syringe volume) × Syringe units = 10.0 units
(Required volume ÷ Syringe volume) × Syringe units = 10.0 units
