AOD-9604 vs Noopept

Side-by-side comparison of key properties, dosing, and research.

Fat Loss & Metabolic
AOD-9604
Cognitive Enhancement
Noopept
Summary
AOD-9604 is a modified fragment of human growth hormone (residues 177-191) with an additional tyrosine residue that significantly enhances bioavailability. Originally developed as an anti-obesity drug by Metabolic Pharmaceuticals, it stimulates lipolysis and inhibits lipogenesis without the diabetogenic effects of full GH.
Noopept is a potent dipeptide-derived nootropic from Russia, structurally related to piracetam but estimated to be 1,000 times more potent by mass. It enhances memory consolidation, learning, and recall while providing neuroprotection via BDNF and NGF upregulation.
Half-Life

~5–10 minutes but metabolite (CPG) effects last hours
Admin Route
SubQ, Intranasal, Oral
Oral, Sublingual, Intranasal
Research
Typical Dose
300-600 mcg
10–30 mg
Frequency
Once daily
1–2x daily
Key Benefits
  • Selective fat loss without anabolic side effects
  • No effect on blood glucose or insulin resistance
