GHRP-6 in research
GHRP-6 is the older of the two ghrelin-receptor hexapeptides listed here, and its ancestry shows: the first growth hormone releasing peptides were developed from met-enkephalin analogues, and this sequence — His-D-Trp-Ala-Trp-D-Phe-Lys-NH₂ — is the compound that established the class. Set against GHRP-2 the differences sit in the first three positions: histidine rather than D-alanine at the amino end, and D-tryptophan where GHRP-2 carries the synthetic naphthylalanine. The histidine imidazole gives GHRP-6 a charge that shifts across the physiological pH range, which its counterpart does not show, and the two tryptophans give it a far stronger ultraviolet signature than most sequences in this range. Registered under CAS 87616-84-0, formula C46H56N12O6, mass 873.0 g/mol, in a 10mg vial.

Frequently asked questions
What separates GHRP-6 from GHRP-2 structurally?
The first three residues. GHRP-6 opens His-D-Trp-Ala; GHRP-2 opens D-Ala-D-2-Nal-Ala, swapping the D-tryptophan for a synthetic naphthylalanine. Both close D-Phe-Lys-NH₂ and both are amidated hexapeptides, but they are separate compounds, 56 g/mol apart and holding their own registry identities.
Does the histidine affect handling?
Its imidazole side chain has a pKa near neutral, so the net charge on the peptide shifts across the physiological pH range in a way the other secretagogues here do not. That matters for ion-exchange chromatography and for buffer selection during analysis.
Is "growth hormone releasing peptide" a description of a use?
No — it is a historical class name from the pharmacology literature, applied to a family of synthetic secretagogues characterised in cell and animal models. It describes where the compound sits in a research taxonomy. Index Peptides supplies GHRP-6 for laboratory research only and cannot advise on any application beyond that.
Documentation & batch verification
GHRP-6 is analysed per batch: RP-HPLC for purity and LC-MS for identity, with the certificate of analysis available on request. Each released lot number is checkable on our batch verification page, and our documentation standards set out exactly what is reviewed before a product is listed.
