GHRP-2
GHRP-2 is a potent GH-releasing peptide designed to boost natural growth hormone production through receptor activation in the brain and pituitary. It is frequently used in studies exploring muscle growth, fat loss, recovery, endocrine balance, and metabolic regulation. In research models, GHRP-2 has been shown to produce pulsatile increases in GH with relatively short duration of effect.

Key Highlights
Strong GH Stimulation
GHRP-2 reliably increases nightly and daytime GH pulses in a dose-dependent manner.
Synergizes with GHRH Peptides
Works well when combined with GHRH analogues (like CJC-1295) to amplify GH output.
Supports Body Composition
Associated with lean mass gain, fat loss, and improved metabolic markers in many models.
Appetite Modulation
Because GHRP-2 acts via the ghrelin receptor, it often stimulates appetite.
Anti-inflammatory Potential
Some preclinical data suggest GHRP-2 may reduce inflammation in arthritis models.
Well Tolerated in Studies
In human research, GHRP-2 was generally safe, with minimal observed toxicities.
Included in the Box

What Is GHRP-2?
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic peptide that acts as a growth hormone secretagogue. It stimulates the pituitary and hypothalamus—via the ghrelin receptor—to release growth hormone (GH). It’s considered more powerful than some earlier GHRPs, and is often used in research that studies GH dynamics, metabolism, and tissue regeneration.
Why Choose GHRP-2?
Researchers select GHRP-2 because of its powerful and reproducible GH release profile, which is highly useful in studies examining growth hormone dynamics, metabolic health, recovery, and aging. Its ability to synergize with GHRH peptides allows modulation of both pulse amplitude and frequency. Its relatively short half-life gives more control over GH episodes, reducing prolonged exposure risks and better modeling physiological pulsatility. In well-controlled production (ISO/cGMP-analogous standards) with rigorous purity and endotoxin screens, it becomes a dependable tool for endocrine and metabolic research.
GHRP-2 FAQs
How does GHRP-2 stimulate GH release?
GHRP-2 binds to the ghrelin receptor (GHS-R1a) in the hypothalamus and pituitary, inhibiting somatostatin and promoting GH release.
What dosage ranges are used in research?
In human and animal settings, protocols often use 100 to 300 µg per injection, multiple times per day.
What’s the duration of effect (half-life)?
GH release from a GHRP-2 dose is relatively short, often peaking within 15–60 minutes and tapering thereafter.
Can GHRP-2 increase appetite or weight?
Yes. Because it acts via the ghrelin pathway, GHRP-2 may stimulate hunger and increase food intake in many subjects.
What are known side effects or risks?
Some risks include increased cortisol or prolactin levels, excessive appetite (leading to unwanted weight gain), and hormonal fluctuations.
How should it be stored and handled?
As with most peptides, it is shipped as lyophilized powder. It must be reconstituted under sterile conditions, stored refrigerated, and handled in a lab-grade manner.
Can GHRP-2 be combined with other peptides?
Yes — notably with GHRH analogues (e.g. CJC-1295) to enhance GH release, or in regenerative stacks with healing peptides.
