Dosing
How much do I take?
Subcutaneous: A small injection into the fatty layer just under the skin — the same way insulin is given.
Bioavailability High — most of the dose reaches your bloodstream, just more gradually than an IV.
3 documented dose levels — separate regimens, not a titration schedule
250 mcg
Frequency
Once daily
Duration
2-4 weeks
300-400 mcg
Frequency
Once daily
Duration
8-12 weeks
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.
Adjusting your dose
Increase if
- Tolerating current dose well with no side effects after 2-3 weeks
- Fat loss progress has stalled despite consistent diet and exercise
- Seeking enhanced fat oxidation during intensive training phases
Decrease if
- Experiencing persistent headaches or flushing
- Injection site reactions are bothersome
- Any signs of allergic reaction occur
Signs of right dose
- Gradual reduction in body fat, especially in stubborn areas
- No significant side effects
- Improved body composition without muscle loss
- Stable energy levels throughout the day
Administration
How do I use it?

What you need
Injection
Route
Subcutaneous injection into fatty tissue

Storage
Before reconstitution
Refrigerate at 36-46°F (2-8°C) for up to several months. Can also be stored frozen at -4°F (-20°C) for longer-term storage. Keep in original packaging away from light.
After reconstitution
Refrigerate immediately at 36-46°F (2-8°C). Never freeze after mixing with bacteriostatic water. Store away from light. Discard after 28 days or if any degradation signs appear.
Signs of degradation — discard the vial
Sample daily schedule
Morning (upon waking, 6-8 AM)
250-500mcg injection
Site: Abdomen or target fat area
Inject on empty stomach. Wait 30-60 minutes before eating. Best before fasted cardio if exercising.
Alternative: Before bed (optional split dose)
250mcg injection
Site: Abdomen or outer thigh
If splitting a 500mcg daily dose, take second injection before bed on empty stomach. Allow 3+ hours after last meal.
Safety
Is it safe?
Side effects
Commonly reported: Injection site reactions, Mild headache, Flushing or warmth
Less common: Fatigue, Dizziness
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

Published research
What the studies show
Ng FM et al. · 2000
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.
Heffernan MA et al. · 2001
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.
Heffernan M et al. · 2001
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.
Kwon DR et al. · 2015
AOD-9604 injections enhanced cartilage regeneration in arthritic joints, with the combination of AOD-9604 plus hyaluronic acid showing the best results for joint repair.
Metabolic Pharmaceuticals; Stier H, et al. · 2007
In a 12-week randomized trial of ~300 obese adults, AOD9604 was tested at 1, 5, 10, 20 and 30 mg daily; the 1 mg dose produced the greatest weight loss versus placebo, with no added benefit from higher doses.
