What is GHRP-6?

GHRP-6 was among the first synthetic growth hormone secretagogues developed and remains a cornerstone in GH-axis research. Its pronounced appetite-stimulating properties, driven by ghrelin receptor activation, make it uniquely useful in feeding behavior research.

Research Applications

GH release studies, appetite and ghrelin signaling research, wasting/cachexia models, and gastroprotection studies.

Dosage Information (Research Use)

100-300 mcg subcutaneously, 1-3 times daily. Research use only.

Reconstitution & Handling

Standard BAC water reconstitution.

Half-Life & Pharmacokinetics

Approximately 20-30 minutes.

Reported Observations in Literature

Pronounced appetite increase, cortisol elevation, prolactin elevation, water retention, potential blood sugar impact.

How GHRP-6 Works

GHRP-6 is a first-generation growth hormone secretagogue acting on GHS-R1a. Produces robust GH release with significant ghrelin-like appetite stimulation. Elevates GH, cortisol, and prolactin. The strongest appetite-stimulating GHRP.

Research Findings

Foundational compound in GHRP research. Still widely used in feeding behavior and appetite signaling studies. The pronounced appetite effect is considered a feature, not a bug, in underweight/wasting research models.

Dosage & Administration

100-300 mcg subcutaneously, 1-3 times daily. Research use only.

Safety & Side Effects

Pronounced appetite increase, cortisol elevation, prolactin elevation, water retention, potential blood sugar impact.

Important: All safety information is derived from published research, primarily animal studies. No controlled human clinical trial data exists unless explicitly noted. This compound is sold for research purposes only.
