GHRP-2 Peptide Vial (Pralmorelin)

GHRP-2 (Pralmorelin), also known as Growth Hormone Releasing Peptide-2, is a synthetic hexapeptide secretagogue available at Direct Anti Peptide at ≥98% purity, supplied as a lyophilized vial for laboratory research applications. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

GHRP-2 is a potent synthetic growth hormone secretagogue that acts primarily at the growth hormone secretagogue receptor (GHSR-1a). It belongs to a class of research peptides widely investigated in preclinical and in vitro settings for its ability to stimulate endogenous growth hormone release. At Direct Anti Peptide, researchers can buy GHRP-2 peptide vials online with confidence, knowing each batch is produced to the highest analytical standards. This compound has attracted significant scientific interest across disciplines including endocrinology, metabolic research, and cellular biology, making it one of the most sought-after research peptides available for sale today.

Peptide Structure & Amino Acid Sequence

GHRP-2, chemically designated as Pralmorelin, is a synthetic hexapeptide with the amino acid sequence D-Ala-D-β-Nal-Ala-Trp-D-Phe-Lys-NH₂. Its molecular formula is C₄₅H₅₅N₉O₆ with a molecular weight of approximately 817.99 g/mol. The CAS number for GHRP-2 is 158861-67-7. Unlike its predecessor GHRP-6, GHRP-2 demonstrates a stronger binding affinity at the GHSR receptor and does not significantly elevate cortisol or prolactin in comparative research models, making it a structurally refined tool for in vitro and ex vivo GH-axis research.

Purity & Analytical Verification (HPLC & MS)

Every GHRP-2 peptide vial supplied by Direct Anti Peptide is independently verified to achieve ≥98% purity using reverse-phase High-Performance Liquid Chromatography (HPLC). Mass Spectrometry (MS) confirmation is conducted to authenticate the molecular identity of each batch, ensuring that researchers receive a product that meets the rigorous analytical benchmarks required for reproducible scientific investigation. Certificates of Analysis (CoA) are available upon request, providing full transparency into purity profiles and batch-specific data.

Quality Control & Lyophilization Integrity

GHRP-2 is supplied in lyophilized (freeze-dried) form, a preservation method that maximizes long-term stability by removing residual moisture and preventing peptide degradation. The lyophilization process is performed under controlled pharmaceutical-grade conditions, ensuring structural integrity is maintained from production through delivery. Each vial is sealed under inert gas and housed in sterile, tamper-evident packaging to minimize contamination risk and preserve potency throughout its shelf life. Batch-to-batch consistency is a cornerstone of our quality assurance protocols at Direct Anti Peptide.

Safety, Handling & Laboratory Precautions

GHRP-2 peptide vials are intended exclusively for use by trained research professionals in properly equipped laboratory environments. Standard laboratory safety practices must be followed at all times, including the use of appropriate personal protective equipment (PPE) such as gloves, lab coats, and eye protection. This compound should be handled in accordance with institutional biosafety guidelines. Avoid exposure to excessive heat, light, or humidity, as these may compromise the integrity of the lyophilized peptide. Dispose of all materials in compliance with applicable local and national regulations governing laboratory waste.

Reconstitution, Packaging & Storage

For laboratory reconstitution, researchers should refer to peer-reviewed literature and institutional protocols relevant to their specific experimental design. Reconstitution should be performed under sterile conditions using appropriate laboratory-grade solvents as dictated by the research methodology. Once reconstituted, the peptide solution should be aliquoted and stored at −20°C to prevent repeated freeze-thaw cycles that may degrade peptide integrity. Lyophilized vials should be stored at −20°C for long-term preservation or at 2–8°C for short-term use, away from direct light and moisture.
