What is AOD-9604?
A GH-fragment–derived peptide primarily discussed for fat loss and body-composition change, sometimes with cartilage and joint-repair context.
Full AOD-9604 profile, mechanism & studies →What is HCG (Human Chorionic Gonadotropin)?
HCG (Human Chorionic Gonadotropin) is a glycoprotein hormone produced by the placenta during pregnancy, structurally similar to luteinizing hormone (LH). It plays a crucial role in regulating reproductive processes in both men and women. In clinical settings, HCG is primarily used to stimulate endogenous testosterone production in men with hypogonadism and to support fertility treatments in women, particularly in assisted reproductive technologies such as in vitro fertilization (IVF).

Can you stack AOD-9604 and HCG (Human Chorionic Gonadotropin)?
People sometimes combine peptides that target different pathways, but there is little controlled research on this specific pairing and the interactions aren't well characterized. Because at least one is a research-use compound, we don't publish stacking or dosing protocols here. Any combination should be discussed with a qualified clinician.

Frequently asked questions
Is AOD-9604 or HCG (Human Chorionic Gonadotropin) better?
It depends on your goal. AOD-9604 is strongest for skin; HCG (Human Chorionic Gonadotropin) for metabolic. HCG (Human Chorionic Gonadotropin) has more indexed studies (57). See the goal-by-goal breakdown above.
Is AOD-9604 or HCG (Human Chorionic Gonadotropin) better for weight loss?
AOD-9604 shows the stronger metabolic & appetite profile (3.0/5) in the AI-assigned effect profile — though weight-loss outcomes depend on the individual and the evidence base.
Is AOD-9604 or HCG (Human Chorionic Gonadotropin) better for muscle?
Both land close on the muscle & body-composition axis.
Which has more research, AOD-9604 or HCG (Human Chorionic Gonadotropin)?
AOD-9604 has 12 approved studies indexed (Human evidence); HCG (Human Chorionic Gonadotropin) has 57 (Human clinical). Higher counts mean more to read, not proven superiority.
Can you stack AOD-9604 and HCG (Human Chorionic Gonadotropin)?
Some users combine peptides, but there's little controlled data on this specific pairing, and interactions aren't well characterized. We don't publish stacking protocols for compounds that aren't FDA-approved. Discuss any combination with a qualified clinician.
What are the side effects of AOD-9604 vs HCG (Human Chorionic Gonadotropin)?
AOD-9604: no community-reported effects logged yet. HCG (Human Chorionic Gonadotropin): none logged yet. These are anonymous reports, not incidence rates — see each profile.
Is AOD-9604 or HCG (Human Chorionic Gonadotropin) FDA-approved?
AOD-9604 is a research-use compound and is not FDA-approved. HCG (Human Chorionic Gonadotropin) is FDA-approved. Research-use status is not a legal clearance to compound or use in humans.
Is HCG (Human Chorionic Gonadotropin) better than AOD-9604?
For metabolic, HCG (Human Chorionic Gonadotropin) has the edge; for skin, AOD-9604 does. Neither is universally "better" — it's goal-dependent, and both should be weighed against their evidence base above.

Regulatory & legal status
Approval status varies (see the chips at the top). FDA approval and compounding rules for peptides change frequently, and research-use status is not a legal clearance for human use. The FDA does not review compounded drugs for safety, effectiveness, or quality. Verify current status with primary sources before acting. Last reviewed November 4, 2026.
