TL;DR

AOD-9604 is a fragment of human growth hormone (residues 176–191) that promotes fat oxidation without the growth-promoting effects of full HGH. Modest standalone fat loss, useful as a stack adjunct. Standard dose: 300–500µg daily, subcutaneous, fasted morning. Cycles 8–12 weeks.

What AOD-9604 is

AOD-9604 ("Anti-Obesity Drug 9604") was developed in the late 1990s by Metabolic Pharmaceuticals as a synthetic analog of the C-terminal fat-mobilizing fragment of HGH. It was studied for obesity but never reached commercial therapeutic approval; it does have status as a premium peptide and is listed by GRAS in some food contexts.

Mechanism: PubMed: 16081814 (AOD-9604 mechanism). Phase-2: PubMed: 21219339.

How it works

AOD-9604 binds to beta-3 adrenergic receptors on adipocytes, promoting lipolysis (release of fatty acids from fat cells) and fat oxidation. Crucially, it does not bind to GH receptors — so it doesn't raise IGF-1, doesn't promote tissue growth, and doesn't cause the side effects associated with full HGH.

This is the key differentiator: AOD-9604 isolates the fat-loss benefit of GH while skipping the muscle/tissue-growth effects.

Trial evidence

The Phase-2 study (Metabolic Pharmaceuticals, 12 weeks, N=300+ obese adults) showed:

  • Mean weight loss ~2.6 kg vs placebo 0.8 kg at 12 weeks
  • Predominantly fat-mass loss
  • No significant impact on lean mass
  • Clean safety profile

Magnitude is modest compared to GLP-1-class peptides. AOD-9604 is best framed as a stack adjunct, not a primary fat-loss tool. PubMed: 21219339.

Dosing protocol

  • Dose: 300–500µg (0.3–0.5 mg) per day
  • Route: subcutaneous
  • Timing: morning, fasted (lipolysis is best with low circulating insulin)
  • Frequency: daily, 5 days on / 2 off, OR 7 days on / 0 off depending on protocol
  • Cycle: 8–12 weeks on, 4 weeks off

Reconstitution

2mg vial + 1mL BAC water = 2mg/mL = 2,000µg/mL. So 0.25mL = 500µg. Reconstitution principles: reconstitution guide. Storage: cold-chain handling.

Stacking strategies

1. AOD-9604 + Tirzepatide

Tirzepatide handles appetite suppression; AOD-9604 enhances fat oxidation when caloric deficit is in place. Common at end-of-cycle to push past plateaus. See Tirzepatide dosage guide.

2. AOD-9604 + MOTS-c

Mitochondrial efficiency (MOTS-c) plus fat mobilization (AOD-9604) is a body-recomp pairing for athletes. MOTS-c review.

3. AOD-9604 + cardio focus

If you train fasted morning cardio, dosing AOD-9604 30–60 minutes pre-cardio amplifies fatty-acid availability for fuel.

Expected results

Stand-alone With proper diet/training
~2–3 kg over 12 weeks 5–7 kg over 12 weeks

Stacked with Tirzepatide, attribution becomes mixed — expect 1–2 kg incremental over Tirzepatide alone, mostly from improved fat oxidation rate.

Side-effect profile

AOD-9604 has one of the cleaner safety profiles in the peptide space. Reported:

  • Mild injection-site soreness
  • Occasional flushing
  • Rare headache (typically dehydration-linked)
  • No measurable IGF-1 elevation
  • No water retention
  • No hypoglycemia at standard doses

Pregnancy/lactation: contraindicated.

AOD-9604 vs Tirzepatide for fat loss

AOD-9604 Tirzepatide
Mechanism Adipocyte lipolysis GIP/GLP-1 appetite + glycemic
Magnitude (12 weeks solo) ~3% body weight ~10–12% body weight
Side effects Minimal GI symptoms during titration
Cost in PH ~₱1,500/vial ~₱2,000–3,500/vial
Best use Stack adjunct, plateau-breaker Primary weight-loss driver

Comparison background: Tirzepatide vs Retatrutide.

Who's a fit candidate

  • Customers already running a primary peptide and wanting fat-oxidation enhancement
  • Athletes wanting body-recomp without weight-class change
  • Customers with appetite control already in hand who need a clean fat-mobilization tool
  • Older customers wanting GH-fragment effects without IGF-1 elevation

Common mistakes

  • Expecting GLP-1-class results from AOD-9604 alone — the magnitude is much smaller
  • Dosing without a caloric deficit — AOD-9604 mobilizes fat, but you still need an energy gap to actually lose
  • Dosing post-prandially — high circulating insulin blunts lipolysis
  • Skipping cycle breaks — 8–12 weeks on / 4 weeks off is the published cadence

How this applies in the Philippines

Pricing reference (May 2026):

  • AOD-9604 2mg: ₱1,500/vial
  • 12-week solo cycle (~10–12 vials at 500µg daily): ~₱15k–18k
  • Use BULK20 code for 20% off ₱15k+

FAQ

Will AOD-9604 raise my IGF-1?

No — the 176–191 fragment doesn't activate GH receptors. IGF-1 stays at baseline.

Can I use it with intermittent fasting?

Yes — dosing during the fasted window aligns with peak lipolysis and is the standard protocol.

Is daily dosing safe?

Daily dosing for 8–12 weeks is the published cadence. Take the 4-week off-cycle.

Does it cause hunger?

No appetite stimulation reported. Some users note slight appetite reduction.

Can I take it with caffeine pre-workout?

Yes — caffeine + AOD-9604 + fasted cardio is a common pre-cardio stack for accelerated fat oxidation.

How does it compare to clenbuterol or DNP?

Cleaner safety profile, smaller magnitude. AOD-9604 is the conservative, longer-game tool.
