The Potential of GHRP-6 Peptide

GHRP-6 Peptide and Memory

For some time now, researchers have been actively investigating physical exertion's function in cementing and storing new knowledge and building memories. Even though the precise mechanism responsible for this action has not been identified, there has always been prevailing research to suggest that engaging in physical activity may promote cognition and learning. 

At first, the positive potential of physical movement on cognition was attributed to increased blood flow and hazy allusions to growth hormone (GH). Studies suggest that because GHRP-6 may aid in cementing long-term memory recall and transforming short-term memories into long-term storage, research in mice has helped to elucidate why GH may be a crucial element in creating memories. This information was gleaned through studies conducted on rats [1, 2]. There is also substantial study data to speculate a function for ghrelin/GHRP-6 in spatial learning tasks [i]. This process lends credence to the hypothesis that growth hormone secretagogues like ghrelin may mediate the cognitive advantages of exercise and that the action of GH may be indirect and secondary to the potential action of these peptides. 

GHRP-6 Peptide and Brain Tissue 

The potential capacity of GHRP-6 to protect neurons and other cells in the central nervous system from the consequences of inadequate blood flow is investigated using animal models of stroke. Prompt delivery of the peptide GHRP-6 may preserve brain tissue during an acute stroke and may potentially restore memory problems that may have occurred due to the stroke [4, 5]. Researchers speculate that ghrelin and its analogs may suppress apoptosis, also known as programmed cell death, and decrease inflammation in the brain, shielding neurons from their genetic programming and the environment in which they are located after a stroke.

GHRP-6 Peptide and Neuron Protection

Research findings in 2018 suggested that ghrelin receptors are present in the substantia nigra, a brain region afflicted by neurological dysfunctions like Parkinson's disease. These findings brought into closer focus the potential of GHRP-6 to preserve brain tissue. Test subjects exhibiting and possessing hereditary ties to neurological decline may exhibit a reduction in the expression of ghrelin receptors on neurons in the substantia nigra. In addition, mice with the same abnormality were reported to exhibit signs of Parkinson's disease when under the influence of an antagonist [ii]. Scientists speculate that by binding to the decreased receptors, the peptide might minimize apoptosis in the neurons of the substantia nigra, delaying the development of Parkinson's disease or possibly preventing it. 

GHRP-6 Peptide and Skin

Studies suggest that by inhibiting programmed cell death, GHRP-6 may promote an increase in the number of different cell types that can survive. Additionally, the peptide may connect with the CD36 receptor, a protein that stimulates blood vessel formation, especially in injured areas. Findings from studies conducted on rats suggest the potential properties that make GHRP-6 so interesting in wound healing may include the following:

• A potentially increased rate of wound closure.
• Potentially improved formation of extracellular matrix proteins like collagen.
• Possible interference with the normal process of scar formation.

All of these properties may work together to help organize the overall structure at the site of the wound and reduce the appearance of scar tissue [iii].

It has also been hypothesized that the peptide may prevent the formation of hypertrophic scars. Both keloids and hypertrophic scars result from abnormal protein depositions in the extracellular matrix. Keloids are more common. Studies suggest the potential of GHRP-6 to stop this process from taking place, with test subjects exhibiting this abnormal healing process [iv] may have these impacts mitigated. 

GHRP-6 Peptide and the Heart

Researchers speculate GHRP-6 may effectively prevent oxidant cytotoxicity in pig models of heart attack [v]. The researchers suggest the peptide may prevent free radicals from damaging heart cells. 

GHRP-6 Peptide and Sexual Functions 

The findings from studies conducted on male rats suggest ghrelin receptors in the central nervous system may influence sexual behavior and motivation. For example, having higher amounts of the hormone ghrelin might increase sexual drive. Research using GHRP-6 and a modified version of GHRP-6 intended to inhibit the ghrelin receptor has suggested that ghrelin receptors in certain parts of the brain assist in governing reward-seeking behavior and sexual behavior [vi].
