Description
Every AOD-9604 5mg vial at Prime Peptides holds 5mg of AOD-9604, packed as freeze-dried powder. In short, it’s a modified hGH fragment. It’s sold for laboratory research only.
AOD-9604 at a glance
AOD-9604 is a modified fragment of human growth hormone (residues 177-191 with an added tyrosine). It was developed at Monash University to study fat metabolism without GH’s effects on growth or IGF-1.
Metabolic Pharmaceuticals took it into trials.
The mechanism behind AOD-9604
Growth hormone has a region near its C-terminal end, residues 177 to 191, that seems to account for its effect on fat breakdown. AOD-9604 is that fragment with a tyrosine added at the front.
In animal studies it increased lipolysis and reduced lipogenesis in fat cells. It doesn’t bind the growth hormone receptor the way full GH does, and it didn’t raise IGF-1 in trials, which is what made it interesting as a tool for separating GH’s fat effects from its growth effects.

What the literature says about AOD-9604
Heffernan and colleagues reported in 2001 that it reduced body fat in obese mice.
Phase 2b trials didn’t show significant weight loss compared with placebo.

AOD-9604 compared with similar compounds
Quick context: AOD-9604 is a modified 176-191 fragment of growth hormone, studied for fat breakdown without GH’s growth effects. Other compounds in the same area:
- Retatrutide activates three receptors at once: GIP, GLP-1 and glucagon
- Tirzepatide activates two incretin receptors, GIP and GLP-1
- Semaglutide activates the GLP-1 receptor only and lasts about a week, which makes it the most studied compound in the group
- Eloralintide is a newer long-acting amylin receptor agonist from Lilly, studied for appetite and gastric emptying
- MOTS-c is a short peptide coded in mitochondrial DNA and linked to AMPK
Each one approaches metabolism from a different side: gut hormone receptors, amylin, a growth hormone fragment or the mitochondria. Compare them in our weight loss peptides.
AOD-9604 5mg quality and verification
On the Prime vial you’ll see the compound name, the words “Lyophilized Powder” and a research-only notice. File the order confirmation with your notes so each vial can be traced to its delivery.
Independent verification usually means HPLC for purity plus mass spectrometry for identity. One without the other only tells half the story.
A quick note of the order number and opening date on each vial makes troubleshooting far easier later on.
How to dissolve AOD-9604 5mg
Start from the 5mg in the vial and pick a volume. These are the concentrations you get:
- 1mL of diluent gives 5mg per mL
- 2mL of diluent gives 2.5mg per mL
- 3mL of diluent gives 1.667mg per mL
Aim the needle at the glass wall, not the powder, and add the liquid slowly. A gentle swirl does the rest. If a thin film remains, a few minutes in the fridge and another swirl usually clears it. Most labs use our bacteriostatic water.
Storing AOD-9604 5mg
Unopened AOD-9604 5mg keeps best at -20°C. A fridge is fine if you’ll use it soon. After reconstitution it belongs at 2 to 8°C, and most protocols use it up within 28 days.
Reconstitute one vial at a time. Powder lasts months, solution lasts weeks.
