AOD-9604

0.3 mg daily, fasted

Fragment of human growth hormone (amino acids 176–191) engineered in the 1990s to isolate hGH’s fat-burning action from its growth effects. Studied for fat loss and possibly joint/tissue repair; remains investigational with no approval.

Important: AOD-9604 does not reliably dissolve in bacteriostatic water alone. Add 0.6% acetic acid first, then top up with bac water. Going straight to bac water is what makes the vial turn cloudy, gel, or leave floating flakes.

AOD-9604 is hydrophobic, so in plain bac water it clumps instead of dissolving; that is the cloudiness or gel at the bottom of the vial. Dissolve it in a small amount of 0.6% acetic acid first (about 10 to 20% of your target volume, so 0.2 to 0.4 mL for a 2 mL fill), swirl until clear, then add bac water to reach the final volume. The acetic acid counts toward that volume.

  1. Use bacteriostatic water as the diluent.
  2. Add the water slowly, letting it run down the inside wall of the vial rather than onto the powder.
  3. Swirl gently to mix, then leave it to dissolve. Do not shake.
  4. Give it a few minutes. The finished solution should be clear and colourless.
  5. Add 0.6% acetic acid first, about 10 to 20% of your target volume (roughly 0.2 to 0.4 mL for a 2 mL fill), down the inside wall of the vial.
  6. Add bacteriostatic water slowly to reach your target volume (about 1.6 to 1.8 mL for a 2 mL fill), swirling as you go.
  7. If a vial has already gone cloudy in plain bac water, adding 0.6% acetic acid will usually clear it. If it stays cloudy after the acid, the peptide has aggregated and the vial should be discarded.

Protocol

Route: Subcutaneous

Standard protocol (subcutaneous)

  • 0.3 mg (300 mcg) per day, injected fasted in the morning
  • At a 2 mL fill on the 5 mg vial (2.5 mg/mL), 0.3 mg is a 0.12 mL draw (12 units)

Dosing detail

  • Standard dose is 0.3 mg (300 mcg) daily, usually fasted in the morning.
  • A modified GH fragment that targets fat metabolism without raising IGF-1 or overall GH, so it does not cause the water retention or growth effects of HGH.
  • Daily consistency over a cycle is the approach.
  • Generally well tolerated.

Duration

  • Run several weeks to a few months, daily. Often paired with a GH secretagogue like Ipamorelin (AOD in the morning, Ipamorelin before bed).

Notes

  • A fragment of GH studied for fat metabolism without the broader GH effects.
  • Generally well tolerated.
  • Inject subcutaneously and rotate sites.

Storage and handling

  • Keep the powdered (lyophilized) vial in a cool, dark place. Refrigerate it for longer-term storage before mixing.
  • Once reconstituted and refrigerated at 2–8 °C away from light, use the vial within 90 days.
  • Do not freeze a reconstituted vial, and keep it away from heat and sunlight.
  • If the solution turns cloudy, develops floating particles, or shows any other sign of degradation, stop using that vial.
  • Cloudiness right after mixing usually means the wrong diluent, not a bad vial; reach for 0.6% acetic acid before writing it off. Cloudiness that appears days later in a previously clear vial is degradation, and that vial should be discarded.
