- Once daily, usually morning fasted
- Evidence Level
- Human Trials
- Duration
- 12-24 weeks in studies
What to Expect
A modified fragment of human growth hormone (amino acids 177-191) studied for fat metabolism effects without the broader hormonal effects of full GH.
Mechanism of Action
AOD-9604 mimics the lipolytic (fat-burning) effects of growth hormone without affecting blood sugar or tissue growth. It stimulates lipolysis and inhibits lipogenesis by interacting with beta-3 adrenergic receptors on fat cells.
Research Summary
Clinical trials showed modest weight loss effects but failed to meet primary endpoints for FDA approval. Some studies show cartilage regeneration potential. Research demonstrates safety profile similar to placebo with no significant GH-like side effects.

Why This Timing?
AOD-9604 works on fat metabolism. Fasted morning use may enhance fat-burning effects.
Possible Side Effects
Not everyone experiences these effects. Individual responses vary based on dosage, duration, and personal factors.
- ●Generally very well-tolerated
- ●Injection site reactions
- ●Mild headache
- ●Dizziness
- ●Does NOT produce typical HGH side effects
- ●No effect on IGF-1 levels
- ●GRAS status by expert panel
