| Transdermal | 75.3 mcg/cm² loaded (800 µm array); 42.8 mcg/cm² (500 µm array) | Single laboratory exposure · 24-hour release measurement |
| Sublingual | 30 mcg/kg | Single evening administration · Single night |
GHRP-6 dosage by administration route
GHRP-6 oral dosage
Reported-use amounts for GHRP-6 are 0.3 mg/kg, 2x daily, for 4 days.[11]
GHRP-6 is a ghrelin-receptor agonist with GH-release and appetite effects. Appetite stimulation can be a relevant response alongside endocrine activity.[1][2][3][4][11]
GHRP-6 injectable dosage
Reported injectable protocols use 100–300 mcg per administration, 2-3 times daily for 8-12 weeks. An additional reported subcutaneous pattern uses 100–200 mcg per administration one to three times daily for 8–12 weeks. Amount per administration and total daily amount should remain separate when comparing frequencies.[2][3][5][10][6][1][12]
GHRP-6 is a ghrelin-receptor agonist with GH-release and appetite effects. Appetite stimulation can be a relevant response alongside endocrine activity.[2][3][5][4]
GHRP-6 intranasal dosage
Reported-use amounts for GHRP-6 are 0.03 mg/kg, as a single dose.[11]
GHRP-6 is a ghrelin-receptor agonist with GH-release and appetite effects. Appetite stimulation can be a relevant response alongside endocrine activity.[6][2][3][4][11]
GHRP-6 transdermal — ex vivo dissolving microneedles dosage
Dissolving PVA/PVP microneedle arrays carry 75.3 mcg/cm² of GHRP-6 with 800-micrometer needles or 42.8 mcg/cm² with 500-micrometer needles. Release is measured across excised pig skin over 24 hours. These figures describe the peptide loaded onto each skin area, not a measured human absorbed dose.[7][13]
The PVA/PVP arrays dissolve after insertion into the skin sample. Only part of the peptide used during casting remains in the finished microneedles; the initial 2.5 mg casting input is not the final patch payload.[7][2][3][4]
GHRP-6 sublingual dosage
A documented investigational sublingual amount is 30 mcg/kg as a single evening administration. A repeat course is not established, and the endocrine response was limited to a trend rather than a confirmed treatment effect.[6]
GHRP-6 is a ghrelin-receptor agonist with GH-release and appetite effects. Appetite stimulation can be a relevant response alongside endocrine activity.[6][2][3][4]
Frequency and timing
The oral and nasal patterns list pre-meal timing. Injections are commonly timed in the morning, before a workout or before bed. The sublingual exposure is a single evening administration; the experimental transdermal preparation follows its own laboratory schedule.[2][3][5][10][6][1][11][7][13]

GHRP-6 safety and side effects
Side effects and long-term safety
Hunger, 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.[2][3][5][8][9]
Route-specific dosing limits
Long-term unapproved GH-secretagogue use needs lab monitoring and careful exclusion of higher-risk contexts. Reported-use oral and intranasal schedules and additional protocol patterns are not established human treatment regimens or approved product instructions.[2][3][5][8][9][12][11]
