Carl read the papersWhat it actually is
AOD-9604 is the tail end (amino acids 176–191) of human growth hormone, tweaked for stability. This region is linked to GH’s effect on fat metabolism.
The appeal is targeted fat metabolism without GH’s growth or blood-sugar effects — but human results have been mixed.
How it’s thought to work
- Lipolysis — reported to stimulate fat breakdown.
- Reduced lipogenesis — may limit new fat formation in models.
- No IGF-1 spike — doesn’t raise IGF-1 or blood sugar like full GH.
What the research says
Early animal work looked promising, but human trials were largely disappointing for weight loss. It’s also studied for cartilage/joint applications.
- Fat metabolism (mixed human results).
- Cartilage and joint repair research.
- Marketed in some cosmetic/obesity contexts historically.
Reported protocols
These are the doses the peptide community actually reports running (Reddit & forums), alongside published research — logged for education, not as a recommendation to use.
| Parameter | Commonly reported range |
|---|---|
| Community dose | 300 mcg (range 250–500) |
| Frequency | Once daily, AM fasted |
| Route | Subcutaneous |
| Cycle | 10–12 weeks minimum, then 4–8 week break |
| Community tip | Fasted AM + fasted cardio within 30 min; rotate injection sites |
Common use cases
| Goal | Community protocol notes |
|---|---|
| Fat loss | 300 mcg AM fasted, 10–12 wks + break |
| With a calorie deficit | pair with a modest deficit |
| (Reality) | human fat-loss evidence is weak |
Mixing it (reconstitution)
Freeze-dried peptides must be reconstituted with bacteriostatic water before they can be measured. Carl’s calculator turns “mg in the vial + ml of water + target dose” into “units on the syringe” — and tells you how long the vial lasts.

Injection & handling
SubQ once daily, AM fasted — inject then do fasted cardio within 30 min for max lipolysis. Rotate sites. Refrigerate reconstituted, use within ~28 days.
Stacks it appears in
- Used alone — AOD-9604 is usually studied on its own rather than stacked.
