Hexarelin Nasal Spray
Hexarelin is a synthetic growth hormone-releasing peptide (GHRP) that strongly stimulates GH secretion, even more potently than Ipamorelin or GHRP-6. Like Ipamorelin, it can be administered intranasally, though its effectiveness depends on formulation and absorption.

Key Facts About Hexarelin Nasal Spray
1. How It Works
- Hexarelin is a ghrelin mimetic, binding to the GHS-R1a receptor to trigger GH release.
- Unlike Ipamorelin, it has stronger GH-stimulating effects but may also slightly increase prolactin and cortisol (though less than GHRP-6).
- Effects are dose-dependent, with rapid GH spikes (peaking around 15-30 mins after dosing).
2. Intranasal Absorption & Bioavailability
- Possible but variable: Nasal peptides must be properly formulated for absorption.
- Lower than injections: Likely requires higher doses than subcutaneous use.
- Absorption enhancers (like chitosan or cyclodextrins) can improve uptake.
3. Benefits of Hexarelin Nasal Spray
✔ Stronger GH release than Ipamorelin (good for muscle growth & fat loss).
✔ Faster effects than injections (due to rapid nasal absorption).
✔ No needles—more convenient for frequent dosing.
✔ Anti-aging & recovery benefits (improved sleep, skin, joint repair).
4. Potential Side Effects
- Increased hunger (due to ghrelin activation).
- Mild cortisol/prolactin rise (less than GHRP-6).
- Desensitization risk (long-term use may reduce effectiveness; cycling recommended).
- Nasal irritation (if the spray contains harsh preservatives).
Hexarelin Nasal Spray vs. Injections
| Feature | Nasal Spray | Subcutaneous Injection |
|---|---|---|
| Bioavailability | Lower (~30-50%?) | High (~90%+) |
| Dosing | 200-600 mcg per spray | 100-300 mcg per dose |
| Onset | Faster (15-30 mins) | Slower (30-60 mins) |
| Convenience | Easy, no needles | Requires injections |
| Side Effects | Possible nasal irritation | Injection site reactions |
Dosing & Usage Guidelines
For Nasal Spray studies :
- Typical dose: 200–600 mcg per spray (1–2x daily).
- Best times:
- Morning (fasted)
- Pre-workout (for performance/recovery)
- Before bed (to enhance sleep & GH pulse)
- Cycle: 5 days on, 2 days off (to prevent desensitization).
For Injections studies
- Typical dose: 100–300 mcg 1–2x daily.
✅ Hexarelin nasal spray can work if properly formulated, but it may require higher doses than injections.
🔥 Stronger than Ipamorelin but with slightly more side effects (hunger, possible cortisol rise).
⚠ Cycling is crucial (5 days on, 2 off) to avoid receptor desensitization.
