Overview

What Is GHRP-2?

GHRP-2 (Growth Hormone Releasing Peptide-2), also known as Pralmorelin, is a synthetic hexapeptide that acts as a potent growth hormone secretagogue via the ghrelin/GHSR-1a receptor. It is one of the most studied GHRPs, known for producing robust GH release and stimulating appetite pathways.

Also known as Growth Hormone Releasing Peptide-2 (Pralmorelin), GHRP-2 is supplied as a lyophilised research peptide for laboratory use only. Research shows GHRP-2 stimulates GH release in a dose-dependent manner, with stronger GH output than GHRP-6 and Hexarelin in comparative studies. It also increases cortisol and prolactin to a moderate degree. Studies demonstrate synergistic effects when combined with GHRH analogues, producing GH peaks 3-5x greater than either alone.

How GHRP-2 Works — Research Mechanism

Research shows GHRP-2 stimulates GH release in a dose-dependent manner, with stronger GH output than GHRP-6 and Hexarelin in comparative studies. It also increases cortisol and prolactin to a moderate degree. Studies demonstrate synergistic effects when combined with GHRH analogues, producing GH peaks 3-5x greater than either alone.

Potent GH secretagogue via ghrelin/GHSR-1a receptor
Dose-dependent GH release stronger than GHRP-6 in comparative studies
Synergistic with GHRH analogues (3–5× GH peak vs either alone)
Moderate cortisol and prolactin elevation at research doses
Hexapeptide structure (Pralmorelin) with extensive GH axis literature

Research reference

GHRP-2 Dosage — Published Research Protocols

The following reference points are drawn from published research literature. These figures are provided for research reference only and do not constitute dosing recommendations. GHRP-2 is sold strictly for laboratory research use.

Protocol tier	Published research detail
Research reference	Published literature varies by model and endpoint — consult primary sources for protocol-specific dosing in laboratory settings
Administration route	Subcutaneous injection is most common in published peptide research protocols
Frequency	Dosing frequency depends on compound half-life and research design — daily to weekly intervals reported in literature
Available vial sizes	5 mg, 10 mg — select based on your laboratory protocol requirements
Titration	Many research protocols start at lower doses and escalate to assess receptor response and tolerability in models

Research use only: FOR LABORATORY RESEARCH USE ONLY. Not for human consumption, injection, or therapeutic use. All products are sold strictly as research chemicals. By purchasing, you confirm you are 18+ and agree to use products solely for legitimate research purposes.

GHRP-2 Side Effects — Research Findings

Side effect profiles documented in published GHRP-2 research depend on dose, route of administration, and model system. The following are commonly reported findings from research literature — not from personal use contexts.

Injection site reactions common to peptide administration routes
Transient water retention reported in some GH-axis research models
Headache and mild fatigue documented in GHRH/GHRP combination studies
Effects generally resolve with dose adjustment in published protocols

Handling

Reconstituting GHRP-2

GHRP-2 is supplied as a lyophilised powder and must be reconstituted before use in laboratory protocols. Use bacteriostatic water (0.9% benzyl alcohol) for multi-dose vials. Inject diluent slowly down the inside wall of the vial — do not shake vigorously.

Bacteriostatic water is available from EvoPeak. Store reconstituted peptide at 2–8°C and lyophilised powder at −20°C.
