GHR-2 (GHRP-2) dosage by administration route
GHR-2 (GHRP-2) injectable dosage
Reported injectable protocols use 100–300 mcg per administration, 2-3 times daily for 8-12 weeks. Another reported once-daily subcutaneous progression uses 100 mcg in weeks 1–2, 150 mcg in weeks 3–4 and 200 mcg from week 5, over an 8–16-week course. This is distinct from patterns with two or three administrations per day.[1][2][3][4][5][12]
GHRP-2, also known as pralmorelin, activates the ghrelin receptor and stimulates GH release. Appetite and endocrine effects are relevant when assessing tolerability.[1][2][3][6]
GHR-2 (GHRP-2) intranasal dosage
Reported-use amounts for GHR-2 (GHRP-2) are 100 mcg per administration, 2x daily, for approximately 4 wk.[11]
GHRP-2, also known as pralmorelin, activates the ghrelin receptor and stimulates GH release. Appetite and endocrine effects are relevant when assessing tolerability.[7][4][5][6][1][3][11]
GHR-2 (GHRP-2) oral dosage
A documented investigational oral amount is 900 mcg/kg twice daily for 12 months in children with growth-hormone deficiency. This pediatric, weight-based regimen does not define an adult oral dose.[8]
GHRP-2, also known as pralmorelin, activates the ghrelin receptor and stimulates GH release. Appetite and endocrine effects are relevant when assessing tolerability.[8][6][1][3]

GHR-2 (GHRP-2) safety and side effects
Side effects and long-term safety
Appetite change, water retention, glucose and IGF-1 changes, and ACTH, cortisol or prolactin effects are relevant to ghrelin-receptor and GH-axis stimulation. Injectable product quality, pregnancy, active malignancy and sports restrictions also require attention.[1][2][3][9][10]
Route-specific dosing limits
Long-term unapproved GH-secretagogue use needs lab monitoring and careful exclusion of higher-risk contexts. Reported-use intranasal schedules and additional protocol patterns are not established human treatment regimens or approved product instructions.[1][2][3][9][10][12][11]
