AOD-9604 (Advanced Obesity Drug Fragment 176-191 (Modified))

Category: Weight Management. Status: Research compound.

A modified fragment of human growth hormone (amino acids 176-191) that stimulates lipolysis and inhibits lipogenesis. Originally developed as an anti-obesity drug with no effect on IGF-1 or blood glucose.

How it works

Mimics the lipolytic domain of growth hormone (hGH 176-191), stimulating fat oxidation and inhibiting de novo lipogenesis through pathways independent of IGF-1 and growth signaling.

Key facts

  • Molecular weight: 1815.08 Da
  • Half-life: ~2-3 hours
  • Bioavailability: ~90% subcutaneous
  • Storage: Lyophilized: 2-8°C. Reconstituted: 2-8°C for up to 30 days.

Dosing overview

  • Typical dose: 300 mcg
  • Frequency: Daily (morning, fasted)
  • Duration: 12 weeks
  • Route: Subcutaneous injection

Protocol notes

  • Most run ~300 mcg once daily, injected subcutaneously in the morning on an empty stomach.
  • Some split into 2x150 mcg (AM and pre-workout) to align with fasted/active windows.
  • Often stacked with a GH secretagogue (CJC-1295/Ipamorelin) since AOD-9604 itself does not raise IGF-1.

Reported benefits

  • Fat loss without muscle wasting
  • No effect on blood sugar
  • Cartilage repair properties
  • No HGH-related side effects

Possible side effects

  • Injection site soreness
  • Headache
  • Mild stomach discomfort

Research

  • AOD-9604 lipolytic effects in obese subjects (2019): Demonstrated significant fat mass reduction without changes in IGF-1 or glucose tolerance.
  • HGH fragment 176-191 cartilage regeneration (2020): Showed chondroprotective effects and stimulated proteoglycan synthesis in osteoarthritic cartilage.

  • recon_math_ray rated it 5/5 - Works as advertised once you titrate properly: I have tried a lot of weight management approaches over the years and AOD-9604 is the first that actually changed my relationship with food rather than just white-knuckling through hunger. The mental shift happened around week 2. Side effects were manageable. Some GI upset early on that settled by week 3. Mild constipation that fiber and water fixed. Nothing that made me want to stop. Results have been steady and sustainable. Losing about 1-2 lbs per week without feeling deprived. My energy is actually better than before, probably because I am not on the blood sugar roller coaster anymore. T
  • subq_samantha rated it 5/5 - Appetite control is genuinely life-changing: Been running AOD-9604 for about 1 month now and the appetite suppression is real. Not that awful "I cannot eat" feeling, more like the constant food noise just goes quiet. I actually forget about snacking, which never happened before. The first week had some mild nausea, especially after eating too fast or too greasy. Learned to eat slower and smaller portions and it resolved. Energy levels are good, no crashes or fatigue that some people report. Down about 16% body weight with no muscle loss that I can detect. Still hitting my lifts fine. The consistency is what impressed me most, no platea

  • reconstitute_ron rated it 4/5 - Finally broke through my plateau: Skeptical going in because I have been burned by hype before. AOD-9604 actually delivered though. The appetite reduction is subtle but persistent, you just stop thinking about food between meals. First two weeks were rough with some nausea and low energy, but I stuck with the low starting dose and let my body adapt. By week 3 I was feeling normal with clearly reduced appetite. By month 2, the results on the scale were undeniable. Key advice: start at the lowest dose, do not rush titration, eat protein-forward, and stay hydrated. The compound does the heavy lifting on appetite, you just need
  • coastaljason rated it 4/5 - helped me lean out without feeling wrecked: over about 6 months on aod-9604, the main thing i noticed was i kept leaning out without that flat, trashed feeling i’ve had on harsher cuts. i dropped about 39 lbs, which was the whole point for me at 40-ish on the east coast, grinding at a desk all day. small caveat, i still had to stay tight on food.
