GHRP-6: pharmacokinetic study regimen
> Updated:
Human schedule
GHRP-6 is given by subcutaneous injection; the figures below are a generalized reference compiled from published pharmacokinetic data and adult protocols.
This is a concise reference to regimens described for adults; it is not an individual prescription.
GHRP-6 dosing in research protocols accounts for the peptide's short half-life, so the GHRP-6 dosing schedule below is a reference point drawn from published pharmacokinetic data, not a standard for self-administration.
| Period / condition | Dose | Escalation |
|---|---|---|
| Weeks 1–2 | 100 mcg per injection, 3x/day | Starting dose |
| Weeks 3–4 | 200 mcg per injection, 3x/day | Increase if needed |
| Weeks 5+ | 300 mcg per injection, 3x/day | Maximum in this schedule |
The scientific context for this compound, from structure to published studies, is collected in the monograph.
Practical dosing and effect details
GHRP-6 stimulates growth-hormone release through the same ghrelin receptor as endogenous ghrelin, and its own blood half-life is measured in minutes. That is why the described protocols dose it several times a day rather than once: infrequent injections poorly sustain the stimulus across a research window. The escalation on this page (100 mcg per injection for the first two weeks, 200 mcg in weeks 3-4, 300 mcg from week 5 onward, each time three times a day) reflects a gradual rise in the per-injection amount at an unchanged frequency, which is how most described regimens for this peptide are built. A side effect often mentioned alongside growth-hormone stimulation is increased appetite, tied to the same receptor: sources sometimes note it as a practical inconvenience of the protocol rather than a desired outcome. This is reference information for planning a research protocol, not a medical recommendation and not instructions for self-administration.
