GHRP-6 (Growth Hormone Releasing Peptide-6) is a single, non-glycosylated polypeptide synthetic met-enkephalin analogue. GHRP-6 is one of several synthetic met-enkephalin analogues that include unnatural D-amino acids and were developed for their growth hormone-releasing activity. GHRP-6 (Growth Hormone Releasing Hexapeptide) is a hexapeptide of 6 amino acids: L-Histidine, D-Tryptophan, L-Alanine, L-Tryptophan, D-Phenylalanine and L-Lysine. An “L” before the amino acid signifies that it is the endogenous form the amino acid, while a “D” before the amino acid signifies that the amino acid is an analog of the naturally occurring “L” form. GHRP-6 and GHRP-2 (Growth Hormone Releasing Peptide 2) are similar, however GHRP-2 was developed from GHRP-6.
Purity, Formulation & Physical Appearance
GHRP-6 has a peptide purity level that exceeds 99.0% as determined by HPLC. This peptide was synthesized with no additives and is supplied as a white lyophilized (freeze-dried) powder.
Solubility & Storage
It is recommended to reconstitute the lyophilized GHRP-6 in sterile water, which can then be further diluted in other aqueous solutions. Lyophilized GHRP-6 although stable at room temperature for 3-4 weeks, should be stored desiccated below -18°C. Upon reconstitution, GHRP-6 should be stored at 4°C out of direct light for between 10-14 days and for future use below -18°C. Prevent repeated freeze-thaw cycles.
