Primary Benefits
Specifically targets fat cells through beta-3 receptor activation without affecting muscle, blood sugar, or other tissues—one of the most selective fat-targeting compounds available
Extensive human clinical trial data showing excellent tolerability with no effect on glucose metabolism, insulin levels, or IGF-1—safer than full HGH for metabolic support
Emerging research demonstrates cartilage regeneration properties, with animal studies showing enhanced joint repair especially when combined with hyaluronic acid

How much
do I take?
Starting Dose
250 mcg
Begin here to assess tolerance. Inject on an empty stomach, ideally in the morning before food or exercise.
Standard Dose
300-400 mcg
The most commonly used dose range for consistent fat metabolism support. Best taken fasted in the morning.
Advanced Dose
500 mcg
Maximum dose used in clinical studies. Some users split into two 250mcg doses (morning and before bed).
Timing
Best time to take
Morning on an empty stomach, 30-60 minutes before food or exercise
With food?
Best taken on an empty stomach for optimal absorption. Wait at least 30 minutes before eating.
If stacking
Can be combined with GHRP peptides like Ipamorelin at the same time. If using with CJC-1295, inject together for synergistic effects on fat metabolism.

Best For
Targeted Fat Loss
AOD-9604 shines when you want to target stubborn fat deposits. It works by mimicking how growth hormone breaks down fat, but without the side effects of actual HGH. Think of it as a smart missile that targets fat cells specifically.
Body Recomposition
Perfect for those who want to lose fat while maintaining muscle. Unlike many fat loss compounds, AOD-9604 doesn't affect muscle tissue or mess with your blood sugar levels—it's laser-focused on fat metabolism.
Metabolic Enhancement
Ideal for boosting your metabolism naturally. AOD-9604 increases fat oxidation (your body's ability to burn fat for fuel) without the jittery stimulant effects of caffeine or other thermogenics.
Joint Health Support
Emerging research shows AOD-9604 may help repair cartilage and support joint health. Studies in osteoarthritis models show it can reduce cartilage damage, making it a dual-purpose peptide for active individuals.
Metabolically Safe Fat Loss
Unlike many weight loss compounds, AOD-9604 doesn't raise blood sugar, doesn't affect insulin, and doesn't stimulate cell growth. It's one of the gentlest approaches to enhancing fat metabolism available.
Consider Alternatives If
Who Should Avoid

Use with caution if
- !Taking blood thinners—monitor for any unusual bruising
- !History of autoimmune conditions—limited data available
- !Currently using other growth hormone-related compounds
- !History of blood clotting disorders
- !Taking diabetes medications—though AOD-9604 shouldn't affect blood sugar, monitor closely
- !Planning surgery in the near future—discuss with your surgeon

Safety
Is it
safe?
Safety Profile
AOD-9604 has been studied in multiple human clinical trials involving thousands of participants. The safety profile is notably clean—it doesn't affect blood sugar, insulin levels, or cause the typical side effects of growth hormone. Phase 2 trials showed it was well-tolerated even at doses higher than typically used. The most common side effects are mild and injection-site related.
Metabolic Pharmaceuticals invested over $50 million in research, generating extensive human safety data. Multiple Phase 1-2 trials demonstrated excellent tolerability. The compound received GRAS (Generally Recognized as Safe) status for oral use in some jurisdictions. However, Phase 3 trials for obesity were not completed.
Common Side Effects
Experienced by some users
Injection site reactions
Redness, minor swelling, or tenderness at the injection site that typically resolves within hours
Management: Rotate injection sites, ensure proper technique, apply ice if needed
Mild headache
Occasional headache, especially in the first few days of use
Management: Stay well hydrated, usually resolves with continued use
Flushing or warmth
Temporary flushing sensation after injection, lasting minutes
Management: This is normal and harmless—resolves quickly on its own
Less Common
- •Fatigue
- •Dizziness
These typically resolve with continued use or dose adjustment.
Stop and Seek Help If
- ×Signs of allergic reaction (rash, swelling, difficulty breathing)
- ×Persistent side effects that don't improve after dose reduction
- ×Pregnancy confirmed or suspected
- ×Development of any new medical condition—consult your provider
- ×No noticeable benefits after 8-12 weeks of consistent use
- ×Prior to any surgical procedure—discuss timing with your surgeon
Always consult with a healthcare provider before stopping or if you experience any concerning symptoms. This information is for educational purposes and should not replace professional medical advice.
Interactions

- ✓Excellent synergy for fat loss—can be injected together
- ✓Commonly stacked for body recomposition—complementary mechanisms
- ✓Safe to combine; different mechanisms, no interaction concerns
- ✓Safe combination for those seeking fat loss plus recovery benefits
- !Generally not combined—AOD-9604 mimics part of HGH's action
With medications
- ✓Insulin - AOD-9604 does not affect blood sugar, but monitor if diabetic
- ✓Diabetes medications - No known interactions, but monitor blood sugar as always
- ✓Blood thinners - Use caution—may slightly increase bruising at injection sites
- ✓Thyroid medications - No known interactions, safe to use together

Not Seeing Results?
Common reasons
- •Not taking on an empty stomach—fat and food reduce effectiveness
- •Inconsistent dosing—daily consistency is important
- •Dose too low—may need to increase to 400-500mcg
- •Diet not optimized—AOD-9604 enhances fat loss but doesn't replace caloric deficit
- •Not enough time—real results take 6-8+ weeks of consistent use
- •Poor peptide quality—ensure you're getting from a reputable source
- •Expectations too high—AOD-9604 is a gentle compound, not a dramatic fat burner
Key Research
"Metabolic studies of a synthetic lipolytic domain (AOD9604) of human growth hormone"
Ng FM et al., 2000
Finding: AOD-9604 reduced body weight gain by over 50% in obese rats without affecting insulin sensitivity—showing it targets fat metabolism safely without diabetic side effects.
View Study"Increase of fat oxidation and weight loss in obese mice caused by chronic treatment with human growth hormone or a modified C-terminal fragment"
Heffernan MA et al., 2001
Finding: Both growth hormone and AOD-9604 increased fat oxidation and reduced weight gain, but unlike HGH, AOD-9604 did not cause high blood sugar or reduce insulin—making it a safer option.
View Study"The effects of human GH and its lipolytic fragment (AOD9604) on lipid metabolism following chronic treatment in obese mice and beta(3)-AR knock-out mice"
Heffernan M et al., 2001
Finding: AOD-9604 works through beta-3 adrenergic receptors on fat cells—it increases expression of these fat-burning receptors, explaining its targeted fat loss mechanism.
View Study"Effect of Intra-articular Injection of AOD9604 with or without Hyaluronic Acid in Rabbit Osteoarthritis Model"
