GHRP-2: dose range, storage & handling reference
Also known as: Growth Hormone Releasing Peptide 2, Pralmorelin, KP-102
Quick answer
What is GHRP-2?
A growth-hormone-releasing peptide that also raises appetite mildly; often paired with CJC-1295.
GHRP-2 at a glance
| Dose range referenced | Commonly referenced in literature around 100–300 mcg per administration, one to three times daily (research reference only) |
| Studied for | Studied as a growth-hormone secretagogue and appetite-related signaling peptide in research |
| Route referenced in research | Subcutaneous (research) |
| Half-life | ~30 minutes (short-acting) |
| Storage | Lyophilized powder stored refrigerated or frozen away from light; reconstituted solution refrigerated (2–8 °C) and used within a few weeks |

Reconstituting GHRP-2
Concentration is vial contents divided by water added, whatever the compound: a 5 mg vial with 2 mL of bacteriostatic water gives 2.5 mg/mL. The step-by-step reconstitution guide works through the arithmetic, and the free calculator below returns exact syringe units.
This is a reference entry. An expanded profile — mechanism, cited literature, protocol tables and reconstitution math — is being added across the library.
