Growth hormone · Growth hormone stimulation and release
GHRP-2
0.1–0.3 mg, 1–3× daily
Synthetic hexapeptide from the 1990s that mimics ghrelin to stimulate growth hormone release, with possible effects on body composition, sleep, and cellular repair; works synergistically with GHRH analogs. Remains an unapproved research chemical.

Standard bacteriostatic water works fine. A few people prefer plain (non-bacteriostatic) saline because the benzyl alcohol in bac water can sting slightly. This is a soft preference: plain saline is fine for a vial used quickly; bac water gives the longer shelf life for a vial used over weeks.
- Use bacteriostatic water as the diluent.
- Add the water slowly, letting it run down the inside wall of the vial rather than onto the powder.
- Swirl gently to mix, then leave it to dissolve. Do not shake.
- Give it a few minutes. The finished solution should be clear and colourless.
Protocol
Route: Subcutaneous
Standard protocol (subcutaneous)
- 0.1 mg (100 mcg) per dose, one to three times daily, on an empty stomach (30 minutes before food)
- A common simple approach is 0.1 mg (100 mcg) before bed, optionally adding a fasted morning dose
Best paired
- Often combined with a GHRH like CJC-1295 (No DAC) for a bigger pulse than either alone
- Run 8 to 12 weeks, then a break
Dosing detail
- Common dose is 0.1 mg to 0.3 mg (100 to 300 mcg) per shot, one to three times daily.
- Empty stomach, 30 minutes before eating.
- Raises appetite (a ghrelin mimic), which some want and some do not.
- A brief flush after injecting is common.
Duration
- Run 8 to 12 weeks, then a break.
Notes
- A ghrelin-mimic GH secretagogue. Tends to raise appetite.
- Inject subcutaneously and rotate sites.
- A brief flush after injecting is common.
Storage and handling
- Keep the powdered (lyophilized) vial in a cool, dark place. Refrigerate it for longer-term storage before mixing.
- Once reconstituted and refrigerated at 2–8 °C away from light, use the vial within 90 days.
- Do not freeze a reconstituted vial, and keep it away from heat and sunlight.
- If the solution turns cloudy, develops floating particles, or shows any other sign of degradation, stop using that vial.
