A 5 mg AOD-9604 vial mixed with 2 ml of bacteriostatic water holds 2.5 mg/ml. A 300 mcg dose is 0.12 ml — 12 units on a U-100 insulin syringe — and the vial holds 16 doses of that size.
Units on a U-100 insulin syringe (100 units = 1 ml) for AOD-9604 doses from 250 mcg to 500 mcg, by how much bacteriostatic water is in a 5 mg vial. The highlighted row is the 300 mcg dose used above.
| Dose | 1 ml water 5 mg/ml | 2 ml water 2.5 mg/ml | 3 ml water 1.67 mg/ml | Doses per vial |
|---|---|---|---|---|
| 250 mcg | 5 u 0.050 ml | 10 u 0.10 ml | 15 u 0.15 ml | 20 |
| 300 mcg | 6 u 0.060 ml | 12 u 0.12 ml | 18 u 0.18 ml | 16 |
| 500 mcg | 10 u 0.10 ml | 20 u 0.20 ml | 30 u 0.30 ml | 10 |
A 12-unit draw fits comfortably on a 0.3 ml insulin syringe (30-unit capacity), whose 1-unit (often half-unit) markings are easier to read than the 2-unit ticks on a 1 ml syringe.
Unit math only, not a dosing recommendation. The dose range is what published protocols and trials describe; see the AOD-9604 guide for sources.
AOD-9604 is a synthetic fragment of the C-terminal region of human growth hormone (amino acids 176–191). It was developed as a potential obesity treatment to retain HGH's lipolytic activity without its growth-promoting effects.
Half-life: Approximately 30 minutes (plasma)
Typical dose range: 250–500 mcg per injection, once daily (typically fasted)
Class: Modified growth hormone fragment (residues 176–191)
Regulatory status: Not FDA approved. Holds GRAS (Generally Recognized as Safe) self-affirmation in the US as a supplement ingredient. Clinical trials did not show significant weight loss vs placebo.

Need a different unit or a different question? The peptide dose converter moves a dose between mcg, mg and IU, and the AOD-9604 half-life chart shows how concentration accumulates across a dosing cadence. Loading AOD-9604 into a reusable 3 ml pen instead of drawing it with a syringe? The peptide pen calculator turns the same vial into mcg per click and clicks to dial. All of them are listed on the free peptide tools page.
Both. This AOD-9604 calculator converts vial strength, bacteriostatic-water volume, and target dose into milliliters and insulin-syringe units. It does not recommend a medical dose.
This page is pre-filled with 2 ml of bacteriostatic water for a 5 mg AOD-9604 vial because that is a common research ratio. You can adjust the water amount in the full calculator.
12 units on a U-100 insulin syringe, when a 5 mg vial is mixed with 2 ml of bacteriostatic water (2.5 mg/ml). That is 0.12 ml. With a different amount of water the unit count changes — the dose chart on this page lists 1 ml, 2 ml, 3 ml mixes.
16 doses of 300 mcg. The number of doses depends only on vial strength and dose size — adding more or less water changes the volume of each draw, not how many draws the vial holds.
No. It only performs unit math. Dosing, titration, and whether AOD-9604 is appropriate are clinical decisions that should be made with a licensed healthcare professional.
Peptide Protocol remembers your AOD-9604 vial, shows the units for every dose, tracks what is left, and rotates injection sites for you.
