GHRP-6 is a potent stimulator of natural growth hormone release from the anterior pituitary gland, and it also functions as a ghrelin/growth hormone receptor agonist. GHRP-6 is orally and sublingually active and exhibits moderate to high selectivity.

It is one of several ghrelin analogs developed in recent decades, and research has shown that it has positive effects on various bodily functions, including heart muscle cells, memory formation, scar formation, sex motivation, and neurons involved in Parkinson’s disease.

Studies have found that GHRP-6 can improve memory formation by helping to solidify newly formed memories and convert short-term memories into long-term storage. It has also been shown to protect brain tissue during acute stroke and rescue memory deficits following a stroke.

GHRP-6 may be useful in protecting neurons in the substantia nigra and slowing or preventing the onset of Parkinson’s disease. In addition, the peptide is highly effective in wound healing, reducing the appearance of scar tissue and preventing the development of hypertrophic scars.

Furthermore, GHRP-6 has been found to reduce heart problems by protecting heart cells from damage by free radicals, and it can also alter sex motivation and mood by modulating sex behavior and reward-seeking behavior.

Studies have also shown that it can decrease depression and improve function in parts of the brain associated with mood, particularly in the setting of stress. GHRP-6 exhibits minimal to moderate side effects, and in mice, it has low oral and excellent subcutaneous bioavailability.
