Dosage Protocols
| Protocol | Dose | Frequency | Notes |
|---|---|---|---|
| Standalone | 100–300 mcg | 2–3× daily | SC, fasted |
| With GHRH analog | 100–200 mcg | 2–3× daily | Combined injection |
| Diagnostic (Japan) | 100 mcg | Single dose | IV |
Administer on an empty stomach — carbohydrates significantly blunt GH response. Best timing: morning fasted, post-workout, or bedtime (≥2 hours after last meal).
Reconstitution
Reconstitute lyophilized GHRP-2 with bacteriostatic water. Use the peptide calculator for volumes. See the reconstitution guide.
Timing & Cycles
Fasted state is essential for optimal GH response. GHRP-2 can be used continuously without the desensitization issues seen with hexarelin, though some protocols recommend 8-12 week cycles with breaks. Combine with CJC-1295 or sermorelin for synergistic GH release.
Storage
- Lyophilized: -20°C long-term, 2–8°C short-term
- Reconstituted: 2–8°C, use within 28 days
