About AOD-9604
AOD-9604 is a modified fragment of human growth hormone: the C-terminal region (residues 177–191) with a tyrosine added at the N-terminus. Biogenesis Labs supplies AOD-9604 as lyophilized powder in 5 mg vials, for laboratory research use only.
Research-grade vials: AOD-9604 5 mg. Every batch is independently tested — see the Certificates of Analysis.
How to calculate AOD-9604 concentration
concentration (mg/mL) = AOD-9604 in vial (mg) ÷ diluent volume (mL)
- A 5 mg AOD-9604 vial with 2 mL of bacteriostatic water is 2.50 mg/mL (2,500 mcg/mL).
- On a U-100 syringe, 100 units = 1 mL, so each unit holds 25.0 mcg.
- Use 3 mL instead and the same vial reads 1.67 mg/mL, or 16.7 mcg per unit. More diluent lowers the concentration; the AOD-9604 in the vial does not change.
For U-40 syringes (40 units = 1 mL), divide mcg/mL by 40 instead of 100. The calculator above switches between both scales.

Concentration for each Biogenesis Labs vial size across common diluent volumes. “In 10 units” is the AOD-9604 contained in 10 units on a U-100 syringe (0.10 mL).
AOD-9604 5 mg vial
| Diluent | Concentration | mcg / mL | Per U-100 unit | In 10 units | U-100 units per 1 mg |
|---|---|---|---|---|---|
| 1 mL | 5.00 mg/mL | 5,000 | 50.0 mcg | 0.50 mg | 20.00 |
| 1.5 mL | 3.33 mg/mL | 3,333 | 33.3 mcg | 0.33 mg | 30.00 |
| 2 mL | 2.50 mg/mL | 2,500 | 25.0 mcg | 0.25 mg | 40.00 |
| 2.5 mL | 2.00 mg/mL | 2,000 | 20.0 mcg | 0.20 mg | 50.00 |
| 3 mL | 1.67 mg/mL | 1,667 | 16.7 mcg | 0.17 mg | 60.00 |
| 4 mL | 1.25 mg/mL | 1,250 | 12.5 mcg | 0.12 mg | 80.00 |
| 5 mL | 1.00 mg/mL | 1,000 | 10.0 mcg | 0.10 mg | 100.00 |
Values are rounded. Figures describe solution concentration only and are not recommendations.
Reconstituting and storing a AOD-9604 vial
Let the sealed vial reach room temperature, swab both stoppers, and run the diluent slowly down the inside wall of the vial rather than onto the powder. Swirl gently until dissolved — don't shake — and label the vial with the concentration and date. Reconstituted solutions are commonly kept refrigerated at 2–8 °C and protected from light.

AOD-9604 calculator FAQ
What concentration does a 5 mg AOD-9604 vial with 3 mL of bacteriostatic water give?
1.67 mg/mL (1,667 mcg/mL). On a U-100 syringe that is 16.7 mcg per unit, and 10 units hold 0.17 mg.
What concentration does a 5 mg AOD-9604 vial with 2 mL give?
2.50 mg/mL, or 25.0 mcg per unit on a U-100 syringe.
How many U-100 units contain 1 mg of AOD-9604?
It depends on the concentration: units per mg = 100 ÷ concentration in mg/mL. At 1.67 mg/mL (5 mg in 3 mL) 1 mg is in 60.00 units; at 2.50 mg/mL (5 mg in 2 mL) it is in 40.00 units.
How much bacteriostatic water should be added to a AOD-9604 vial?
There is no single correct volume. The volume comes from your own research protocol; the calculator and chart show the concentration each volume produces. Only add a volume your vial can hold.
Why does a 5 mg AOD-9604 vial read lower than most other vials?
Concentration scales with the mg in the vial. With 2 mL of diluent a 5 mg vial is 2.5 mg/mL, half the concentration of a 10 mg vial with the same volume.
Does this AOD-9604 calculator provide dosing guidance?
No. It performs concentration and unit-conversion math only. All Biogenesis Labs products are supplied for laboratory research use only and are not for human consumption.
