What it is

AOD-9604 is a fragment of human growth hormone studied for fat metabolism without the full anabolic effects of GH.

Mechanism of action

AOD-9604 is a synthetic 16-amino-acid peptide corresponding to residues 176–191 of the human growth hormone molecule. The fragment was designed to retain the lipolytic (fat-burning) activity of HGH while removing the growth-promoting and glucose-impairing activity. The mechanism is thought to involve direct stimulation of fat cell lipolysis without IGF-1 elevation.

Reported uses

Evidence base

Limited clinical evidence for body-composition effects in humans.

Regulatory status

Compounded — not FDA-approved.

Typical dosing context

Common protocols: 250–500 mcg subcutaneous daily, often dosed in the morning before exercise or fasted state. Cycles of 8–12 weeks are typical.

Dosing in research and clinical-use contexts varies. Specific protocols should always be set by a prescribing clinician, not by patient-direct sources.

Side effects and safety

Generally well-tolerated in available data. Reported side effects: injection-site irritation, occasional headache. Long-term safety is not well-characterized.

Common stacking protocols

Sometimes layered with growth-hormone secretagogues (ipamorelin/CJC-1295) or tesamorelin for additive body composition effects. Often used alongside dietary interventions and resistance training.

Frequently asked questions

What is AOD-9604?

AOD-9604 is a fragment of human growth hormone studied for fat metabolism without the full anabolic effects of GH.

Is AOD-9604 FDA-approved?

Compounded — not FDA-approved.

What are the typical uses of AOD-9604?

Uses include: Fat-loss adjunct (research). This is research and clinical-use context, not a recommendation. Always work with a licensed clinician.

What is the evidence behind AOD-9604?

Limited clinical evidence for body-composition effects in humans.

What is the typical dosing for AOD-9604?

Reported dosing: 300–500 mcg subcutaneous daily. Actual dosing should always be determined by your prescribing clinician, not by online sources.

Does AOD-9604 actually work?

Clinical evidence is limited. The marketing claims often outpace the evidence. Patients should set realistic expectations and use AOD-9604 as one component of a broader weight-management approach, not a standalone solution.

Is it the same as HGH?

No. AOD-9604 is a fragment of HGH that retains the lipolytic activity but lacks the growth-promoting effects. It does not raise IGF-1.
