What Is GHRP-6?


(Click here to read our disclaimer)

GHRP-6 is a peptide which comprises the AA sequence of H-His-D-Trp-Ala-Trp-D-Phe-Lys-NH2. In studies GHRP-6 has shown biological actions similar to the naturally occurring hunger stimulating peptide ghrelin.

GHRP-6 contains D-amino acids that are entirely synthetic, lacks opioid activity, and shares no sequence relation with GHRH.

It has also been shown that GHRP-6 can lead to re-stimulation of the natural production of GH.

Studies have shown that GHRP-6 increases the secretion of IGF-1 by the liver of some lab rats (Insulin-Like Growth Factor 1), which is speculated to be a required component in the anabolic mechanisms leading to the action of GH. It also appears that GHRP-6 has positive implications for the central nervous system, as ghrelin is known to protect neurons.


What may be the most interesting aspect of ghrelin (and therefore GHRP-6) is the huge variety of roles it plays in biological functions. It is involved in processes in lab rats that include appetite regulation, cardiac functions, gastrointestinal functions, metabolism of carbohydrates, and even has some behavioral effects.

GHRP-6 fills many of ghrelin’s roles, but does not fill all of them. It has been largely shown to focus on the release of GH. Of all synthetic peptides, GHRP-6 is the most ghrelin-like.

When ordering GHRP-6, be sure to choose a research company that:

  • Provides MS and HPLC reports on its products.
  • Has the ability for large scale production thereby lowering cost and improving efficiency.
  • Is committed to customer satisfaction and customer service.

Settle for nothing less than the best in quality peptides.
