GHRP-2 is supplied as a laboratory research reference material intended exclusively for in-vitro and laboratory research use. It is a synthetic hexapeptide amide with the sequence D-Ala-D-2-Nal-Ala-Trp-D-Phe-Lys-NH2, incorporating three non-canonical residues (two D-alanine substitutions, a D-3-(2-naphthyl)alanine at position 2, and a D-phenylalanine at position 5) together with a C-terminal amidated L-lysine. This deliberate stereochemical patterning and the bulky naphthylalanine side chain are the structural features that distinguish GHRP-2 from earlier growth hormone releasing peptide analogs in the published characterization literature.
The identity of GHRP-2 is defined by CAS Number 158861-67-7, PubChem CID 6918245, and InChIKey HRNLPPBUBKMZMT-RDRUQFPZSA-N. The molecular formula C45H55N9O6 corresponds to an average molecular weight of 817.96 g/mol and a monoisotopic mass of 817.4275 Da, the latter serving as the target ion for high-resolution mass spectrometry confirmation. The canonical SMILES representation CC(C(=O)NC(CC1=CC2=CC=CC=C2C=C1)C(=O)NC(C)C(=O)NC(CC3=CNC4=CC=CC=C43)C(=O)NC(CC5=CC=CC=C5)C(=O)NC(CCCCN)C(=O)N)N encodes the six-residue backbone and the primary carboxamide terminus that formulators should confirm during analytical review.
Supplied as a white to off-white lyophilized powder from synthetic origin, GHRP-2 (catalog SKU: GHRP-2) is released at not less than 98% purity by reversed-phase HPLC, with identity and purity documented on the lot-specific Certificate of Analysis available on request. Typical analytical workflows for a hexapeptide of this composition include RP-HPLC with UV monitoring in the 210-280 nm range (leveraging the tryptophan and naphthylalanine chromophores), ESI-MS or MALDI-TOF for mass confirmation against the 817.43 Da monoisotopic target, and Karl Fischer or residual solvent testing as appropriate to the lot.
Published scientific literature has examined GHRP-2 in preclinical research contexts, and it is frequently cited as a reference hexapeptide in receptor-binding, chromatographic method development, and peptide stability studies. PEPTIDE.Power makes no therapeutic, diagnostic, or efficacy claims regarding this material and provides no administration or dosing guidance. This material is not a drug, supplement, cosmetic, or food, and is not intended for human or veterinary use, injection, or ingestion.
