I'm trying to understand the difference between AOD9604 and GLP-1 agonists like Tirzepatide for fat loss.

From my research:

  • AOD9604 = fragment of human growth hormone, targets fat cells directly
  • Tirzepatide = GLP-1/GIP agonist, works through appetite suppression and insulin

So they work completely differently? Could you theoretically stack them?

I'm leaning towards AOD9604 because I don't want appetite suppression — I actually enjoy eating and I'm quite active. I just have stubborn lower belly fat that won't budge.

Anyone used AOD9604 on its own for targeted fat loss? Results?

You're right that they work through completely different mechanisms. AOD9604 is great if you want fat loss without appetite changes — it targets lipolysis directly. Dose at 300mcg/day, first thing in the morning fasted. Stack with Tirzepatide is theoretically fine but usually overkill. For stubborn belly fat without wanting appetite suppression, AOD is the move.

I've used AOD for stubborn fat and it does work, but it's more subtle than Tirzepatide. Expect to see results over 8-12 weeks not 4. The advantage is zero impact on appetite or energy. Pin fasted in the morning, don't eat for 30 mins after.

AOD9604 is one of the safest peptides out there — it's literally a fragment of your own growth hormone. No effect on blood sugar, no appetite changes, no systemic hormonal effects. Great choice for targeted fat loss in someone who's otherwise healthy and active.

Hey Raj,

You're on the right track with understanding the different mechanisms of AOD9604 and Tirzepatide. AOD9604 is indeed a fragment of human growth hormone that specifically targets fat by promoting lipolysis and inhibiting lipogenesis, focusing on breaking down fats. In contrast, Tirzepatide's action as a GLP-1/GIP agonist revolves around appetite regulation and enhancing insulin sensitivity, which can lead to significant weight loss but often through reduced caloric intake.

If you're leaning towards avoiding appetite suppression and just want to target stubborn fat, AOD9604 sounds like a suitable choice. It's great for individuals like yourself who enjoy staying active and prefer maintaining their appetite while addressing specific fat loss areas. As others have mentioned, the effects with AOD9604 can take a bit longer to manifest, so patience is key. Typically, a 300mcg dose first thing in the morning while fasted seems to be a popular approach, as it maximizes the peptide's effectiveness.

Stacking AOD9604 with Tirzepatide is theoretically possible, but it might indeed be overkill if you're not interested in the appetite suppression benefits. Maybe start with the AOD9604 and keep track of your results over a few weeks. We'd love to hear back on how it goes for you!
