Technical Specifications & Chemical Profile

Research Applications & Storage Protocols

GHS-R1a Agonism & Pulsatile GH/IGF-1 Secretion Profiling

GHRP-2 (Pralmorelin) functions as a potent synthetic agonist of ghrelin, the newly-discovered gut peptide that binds to the growth hormone (GH) secretagogue receptor (GHS-R1a), also known as the ghrelin receptor, making GHRP-2 a ghrelin receptor agonist. The compound is a 6-amino acid synthetic peptide with the sequence D-Arg¹-D-2⁴-D-Phe⁷-D-Trp⁹, featuring D-amino acid modifications that enhance stability compared to native peptides. GHRP-2 stimulates growth hormone (GH) release from pituitary somatotroph cells through direct agonism of GHS-R1a, increasing IGF-1 secretion from the pituitary gland, making it valuable for investigating endocrine system regulation and pulsatile GH release dynamics. Research suggests GHRP-2 stimulates GH release through multiple mechanisms: by direct or indirect antagonism of somatostatin (SRIF), which normally inhibits GH secretion; by releasing corticotropin-releasing hormone (CRH); and by potentiating GHRH (growth hormone-releasing hormone)-induced GH release through synergistic action. GHRP-2 works by mimicking the effects of ghrelin, a natural hormone that promotes appetite and growth hormone release, making it valuable for studying appetite stimulation and metabolic regulation. The peptide has been nominated for clinical development for growth hormone deficiency (including adult onset), wasting syndrome, and anorexia nervosa, with oral tablet and capsule formulations at 0.5-5 mg doses under investigation. GHRP-2 offers a wide range of potential benefits by naturally increasing growth hormone levels, including muscle growth, fat loss, recovery enhancement, and anti-aging effects through optimized hormonal balance. The compound has an estimated half-life of 15-30 minutes in humans, making it suitable for studying acute GH responses and short-term hormonal effects, requiring more frequent dosing compared to longer-half-life analogs. This GHS-R1a agonist mechanism positions GHRP-2 as a critical tool compound for investigating GH-axis biology, growth hormone secretion research, age-related hormonal decline models, metabolic enhancement studies, appetite regulation, and neuroendocrine signaling in preclinical models, offering potential therapeutic insights for metabolic and endocrine disorders.

Handling & Storage Guidelines

• Long-Term Storage: Keep lyophilized peptide sealed in original vial, protected from light and moisture; store at -20°C (-4°F) or colder for optimal long-term stability (up to 3 years); short-term storage at 2-8°C (39°F) suffices for immediate use within weeks

• Solubility: Reconstitute with Bacteriostatic Water (10 mL recommended for 5mg vial); swirl gently — do not vortex; avoid repeated freeze-thaw cycles; after reconstitution, store at 2-8°C, protect from light, use aliquots to reduce handling

• Appearance: Lyophilized white to off-white powder; reconstituted solution is clear and colorless; vials arrive at approximately 104% of labeled amount for research accuracy
