Structural Composition
His-D-Trp-Ala-Trp-D-Phe-Lys-NH₂
Physical Properties
GHRP-6 is a synthetic hexapeptide containing D-amino acid substitutions that enhance resistance to enzymatic degradation compared to purely L-configured peptides. The inclusion of D-tryptophan and D-phenylalanine contributes to improved structural persistence under research conditions. Its short chain length supports efficient solubility and practical laboratory handling. Lyophilized storage and protection from moisture, light exposure, and repeated freeze–thaw cycles help preserve peptide integrity and maintain analytical consistency during research applications.
