GHRP-2 (5mg) Dosage Protocol
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide that stimulates GH release through the ghrelin receptor. It is one of the most potent GHRPs with significant GH release but also increases cortisol and prolactin.
Add 2.5 mL bacteriostatic water → 2 mg/mL (2000 mcg/mL)
100-300 mcg per injection, 2-3x daily
At 2 mg/mL: 5 units = 100 mcg, 15 units = 300 mcg
Lyophilized: -20°C; Reconstituted: 2-8°C for up to 4 weeks
| Week | Daily Dose | Units (per injection) |
|---|---|---|
| Weeks 1-2 | 100 mcg 2x daily | 5 units AM + 5 units PM |
| Weeks 3-4 | 150 mcg 2-3x daily | 7.5 units per dose |
| Weeks 5-12 | 200-300 mcg 2-3x daily | 10-15 units per dose |
- 1Draw 2.5 mL bacteriostatic water with a sterile syringe
- 2Inject slowly down the vial wall to prevent foaming
- 3Gently swirl until fully dissolved - do not shake
- 4Label with date and concentration, refrigerate immediately
GHRP-2 activates the ghrelin receptor (GHS-R1a) in the pituitary and hypothalamus, triggering GH release. It produces one of the strongest GH responses among GHRPs. However, it also elevates cortisol and prolactin more than selective alternatives like Ipamorelin.
- Strong GH release response
- May support muscle growth and recovery
- Increases appetite (beneficial for some)
- Synergistic with GHRH analogs

May increase appetite significantly
- •Research compound - not FDA approved
- •Increases cortisol and prolactin
- •Strong appetite stimulation
- •Consider Ipamorelin for cleaner GH release
