Type
AOD-9604 is a synthetic 16-amino-acid fragment (residues 176–191) of the C-terminal region of human growth hormone, modified with a tyrosine addition at the N-terminus. It stimulates lipolysis and inhibits lipogenesis in adipose tissue by activating beta-3 adrenergic receptors, without raising IGF-1, affecting blood glucose, or triggering growth-promoting effects associated with full-length HGH. It has been investigated in human Phase II/IIb trials for obesity and is explored in research contexts for fat metabolism, cartilage repair, and metabolic support.

Overview of AOD-9604
AOD-9604 binds to beta-3 adrenergic receptors on adipocytes, triggering adenylyl cyclase activation and elevated cyclic AMP, which in turn activates protein kinase A to phosphorylate hormone-sensitive lipase — releasing stored triglycerides as free fatty acids for oxidation. It simultaneously inhibits lipogenesis without interacting with growth hormone receptors, preserving normal glucose homeostasis and insulin sensitivity.
fat loss
- Increases fat oxidation, plasma glycerol levels, and reduces body weight in obese models without affecting glucose metabolism.
- Reduces fat synthesis and storage in adipose tissue.
- Does not cause hyperglycemia, reduce insulin secretion, or increase insulin resistance.
joint health
- Enhanced cartilage regeneration when combined with hyaluronic acid in osteoarthritis models.
- Synergistic effects with hyaluronic acid for joint health.

Chemical Makeup
Key benefits
Promotes targeted lipolysis in visceral and subcutaneous adipose tissue by activating hormone-sensitive lipase via the beta-3 adrenergic / cAMP / PKA pathway
Inhibits new fat synthesis (lipogenesis) in adipocytes, helping prevent fat re-accumulation during caloric deficit
Does not elevate IGF-1 or disrupt insulin sensitivity, making it a fat-loss-focused tool without anabolic or diabetogenic side effects of full-length HGH
Phase IIb trial data showed approximately 1.6 kg visceral fat reduction versus 0.3 kg placebo over 12 weeks at 1 mg daily with no changes in glucose or HbA1c
Community interest
This peptide is still gaining traction in the community.

PeptideAOD-9604 Protocols
Subcutaneous injection is the primary and most bioavailable delivery route for AOD-9604, targeting lipolysis and fat metabolism. Administration in the fasted morning state, 30–60 minutes before eating, maximizes beta-3 receptor activation on adipose tissue.
| Goal | Dosage | Frequency | Route |
|---|---|---|---|
| Fat loss / obesity treatment | 300 | 1 day range | SubQ abdomen |
| General weight management | 250 | 1 day range | SubQ abdomen |
| Athletic / performance cutting | 500 | 1 day range | SubQ abdomen |
| Joint and cartilage support | 250 | 1 day range | SubQ abdomen |
| Visceral fat reduction | 500 | 1 day range | SubQ abdomen |
| Conservative introductory protocol | 200 | 1 day range | SubQ abdomen |
Reconstitution Instructions
Materials needed:
Steps to reconstitute
- Remove the AOD-9604 vial from the freezer and allow it to reach room temperature before handling.
- Draw 2 mL of bacteriostatic water into a 3 mL syringe.
- Insert the needle through the rubber stopper of the AOD-9604 vial at a slight angle.
- Inject the bacteriostatic water slowly down the inside wall of the vial — never directly onto the powder cake.
- Remove the syringe and gently swirl the vial until fully dissolved — do not shake or vortex.
- The reconstituted solution yields 2,500 mcg/mL (2.5 mg/mL); store refrigerated at 2–8°C and use within 30 days.
- Draw the target dose into a 0.5 mL insulin syringe: 250 mcg = 0.10 mL (10 IU), 300 mcg = 0.12 mL (12 IU), 500 mcg = 0.20 mL (20 IU).
- Pinch the skin at the injection site (abdomen at least 2 inches from the navel, thigh, or upper arm) and insert the needle at a 45-degree angle.
- Inject slowly and steadily; do not aspirate for subcutaneous injections.
- Rotate injection sites daily to prevent lipohypertrophy.
AOD-9604 Cycle
The AOD-9604 Cycle section explains how long a typical cycle lasts and what to expect during each phase. Over time, your body can become less responsive with continuous use.
Taking breaks between cycles may help maintain effectiveness and support better overall results.
- Week 1-2
- Minimal noticeable effects; compound accumulating
- Week 3-4
- Subtle body composition changes may begin
- Week 5-8
- More noticeable fat loss, especially with diet and exercise
- Week 8-12
- Continued fat reduction and improved body composition

Frequently asked questions
What is a peptide dosage calculator?
A peptide dosage calculator is a free tool that converts your vial size, bacteriostatic water volume, and target dose into an exact syringe draw volume. Instead of doing the reconstitution math by hand, you enter three inputs and instantly get the concentration of your solution and how many milliliters or syringeunits to draw. This calculator works for single peptide compounds and multi-peptide blends.
How do I calculate peptide dosage from a vial?
To calculate your peptide dose, divide the total peptide content of your vial in micrograms by the volume of bacteriostatic water you added in milliliters. This gives you your solution concentration in mcg/mL. Then divide your target dose by that concentration to get your draw volume. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water gives a concentration of 2,500 mcg/mL. A 250 mcg dose would require drawing 0.1mL. This calculator automates all of those steps instantly.
How much Bacteriostatic water should I add to a peptide vial?
Most people add 2mL to 3mL of bacteriostatic water per vial, but the right amount depends on the dose you want to draw and the syringe size you are using. Adding 1mL to a 5mg vial gives you a concentration of 5,000 mcg/mL, making each dose very small in volume. Adding 2mL gives you 2,500 mcg/mL, which is easier to measure on a standard insulin syringe. A general guideline is to choose a volume that puts your typical dose somewhere between 10 and 30 units on a U-100 syringe. Use the calculator above to test different water volumes and find what works for your dose.
How are peptides different from proteins?
Both are made of amino acids, but peptides are much smaller than proteins. Because of their tiny size, peptides can act like tiny messengers in the body, sending specific signals to your cells to tell them exactly what to do.
