GHRP-6 or growth hormone releasing peptide-6 is a synthetic hexapeptide belonging to the category of GH secretagogues. It is highly effective in stimulating the release of growth hormone, which is required by the body to grow and develop, by two completely different mechanisms. GHRP-6, as a functional antagonist of the hormone, inhibits somatostain (GH secretion) and amplifies the natural signal transduction pathway of growth-hormone-releasing hormone (GHRH).

GHRP-6 has a HPLC (high performance liquid chromatography) purity of 99.68 percent and the molecular weight of 873.01 g/mol at the base. Its chemical formula is C46H56N12O6.

Growth hormone releasing peptide-6 brings improvements in the release of growth hormone (GH) by stimulating anterior pituitary gland and is equally effective for stimulating hunger by promoting intake of food. This peptide is also considered effective for treating deficiency of growth hormone, obesity, cachexia, and eating disorders.

GHRP-6 is admired by professional sportsmen as it leads to dramatic muscle size and mass gains besides promoting the levels of stamina, body strength, and performance. It is also useful for burning fat and bringing improvements in performance of body organs and functions such as joints, connective tissues, and bone mass. It is used primarily to restore the natural production of growth hormone after a GH cycle and restoring IGF-1 (insulin like growth factor-1) after an IGF-1 cycle.  GHRP-6 is also admired for stimulating improvements in terms of normal pulsatile physiological secretion via hypothalamic action and pulsatile secretory bursts of GH. In addition to all these amazing benefits, GHRP-6 is also useful for improving sleep and bringing a sense of well being to its users.

The recommended dose of GHRP-6 is 400-600 mcg per week or 100 mcg per day via subcutaneous injections.
