GHRP-6 protocol
GHRP-6 (growth hormone releasing peptide 6). Dosing on this page comes from a published human trial or an approved product label, cited below.
How GHRP-6 works
The earliest of the growth-hormone-releasing hexapeptides and the compound that led to the discovery of the ghrelin receptor. It is a strong GH releaser and a strong appetite stimulant — the hunger is a pronounced, well-documented effect rather than an incidental one.
GHRP-6 dosing schedule
GHRP-6 has been used in human GH-secretion research since the 1980s, typically as a single provocative intravenous dose to study pituitary response. There is no approved therapeutic indication and no established treatment course.
| Phase | Amount | Frequency | Notes |
|---|---|---|---|
| Research provocative dose | 1 mcg/kg | Single intravenous dose | The amount commonly used in GH-secretion research. |
Study length: Single administration in the provocative-test setting.
Reconstitution and measurement
This part is arithmetic and does not depend on the evidence level. Concentration is vial size divided by the bacteriostatic water you add. Draw volume is your target amount divided by that concentration. Units are draw volume times 100, because a U-100 syringe reads 100 units per millilitre.

Storage and stability
Reported effects
- Marked appetite stimulation is the most consistently reported effect and the main practical difference from ipamorelin.
- Raises cortisol and prolactin more than the more selective secretagogues.
- No approved therapeutic indication.
