AOD-9604

Mechanism, Dosing, Effects & Safety

AOD-9604 is a synthetic 16-amino-acid fragment of human growth hormone (hGH 177–191) developed specifically for fat loss. It stimulates lipolysis (fat breakdown) and blocks lipogenesis (fat storage) without increasing IGF-1 or causing insulin resistance.
Human trials show a placebo-like safety profile, making it one of the safest fat-loss peptides studied.

Mechanism of Action

AOD-9604 works by:

Activating fat-burning pathways in adipose tissue
Increasing lipolysis (release of stored fat)
Blocking re-esterification (new fat storage)
Upregulating β3-adrenergic receptors in fat cells
Enhancing fat oxidation
Does NOT raise IGF-1
Does NOT affect blood sugar or insulin sensitivity

Unlike full HGH, it only targets fat metabolism — no growth effects.

Dosing Strategy

Route: Subcutaneous
Frequency: Once daily
Vial: 5 mg

Reconstitution

Add 3.0 mL bacteriostatic water
Final concentration: 1.667 mg/mL
Syringe reference:
- 1 unit = 16.7 mcg

Standard Protocol

Weeks 1–4
→ 300 mcg daily
→ 18 units (0.18 mL)

Weeks 5–12
→ 500 mcg daily
→ 30 units (0.30 mL)

Optional extension: up to 16 weeks

Best Timing

AOD-9604 works best when taken in a fasted state.

Pre-administration:
• Fast 2–3 hours before injection

Post-administration:
• Wait 30–60 minutes before eating

Typical schedule:

• Morning injection
• Fasted cardio afterwards (optional

Cycle Length

Standard: 8–12 weeks
Optional: 16 weeks
Vial usage:
- 500 mcg/day → ~10 days per vial
- 300 mcg/day → ~16 days per vial
