AOD-9604 Nasal Spray Delivery: Dosage, Effectiveness & Safety
AOD-9604 is a modified fragment of human growth hormone (hGH, amino acids 177-191) that has been studied for its potential fat-loss and metabolic effects. Unlike full hGH, it does not significantly affect insulin or growth pathways, making it an attractive option for targeted fat reduction.
Nasal spray delivery of AOD-9604 has gained popularity in anti-aging and weight-loss clinics, as well as in the peptide research community, due to its convenience and potential for systemic absorption.
1. How AOD-9604 Nasal Spray Works
Mechanism: AOD-9604 stimulates lipolysis (fat breakdown) and inhibits lipogenesis (fat storage) by mimicking the effects of hGH on fat cells.
Nasal Absorption: The nasal mucosa allows peptides to bypass the digestive system, potentially improving bioavailability compared to oral administration.
Target Effects:
Reduces stubborn fat (especially abdominal)
May support metabolism without affecting blood sugar
Some reports of improved cartilage repair (anecdotal)
2. Typical AOD-9604 Nasal Spray Dosage
Since AOD-9604 is not FDA-approved, dosing is based on research studies, anecdotal reports, and peptide clinic protocols.
Common Dosage Ranges:
| Form | Dosage | Frequency | Notes |
|---|---|---|---|
| Nasal Spray | 300–600 mcg (0.3–0.6 mg) | 1–2x daily | Most common in clinics |
| Subcutaneous Injection | 250–1000 mcg/day | 1x daily | Traditional method |
| Oral (Less Effective) | 1–2 mg/day | 1–2x daily | Low bioavailability |
Example Nasal Spray Protocol:
300 mcg per spray (1 spray in each nostril = 600 mcg total)
Taken once in the morning (fasted) or twice daily (morning & evening)
Cycles typically last 8–12 weeks, followed by a break
3. Effectiveness of Nasal Spray vs. Injection
| Factor | Nasal Spray | Injection |
|---|---|---|
| Bioavailability | ~30–50% (estimated) | ~80–100% |
| Convenience | Easy, no needles | Requires injections |
| Dosing Accuracy | Less precise | More precise |
| Reported Fat Loss | Moderate (anecdotal) | Stronger (studies) |
Conclusion:
Nasal spray is more convenient but may require higher doses for similar effects.
Injection remains the most reliable method for optimal results.
4. Safety & Side Effects
AOD-9604 is generally well-tolerated, but possible side effects include:
Mild nasal irritation (if using spray)
Headaches (rare)
Increased hunger (some users report)
No significant impact on blood sugar or IGF-1 (unlike full hGH)
Contraindications:
Pregnancy or breastfeeding
Active cancer (theoretical risk, though minimal evidence)
