Sermorelin, GHRP-6, GHRP-2
A combination of growth hormone (GH) releasing peptides can lead to tremendous increases in GH levels, but such a process generally only requires a growth hormone releasing hormone (GHRH) analogue like sermorelin and a growth hormone secretagogue/ghrelin analogue like GHRP-2 or GHRP-6. Combining all three isn’t likely to cause a proportionally greater increase in GH hormone levels, but are other reasons to utilize such a combination.
Sermorelin is an excellent GHRH analogue with strong GH releasing action and very few off-target effects. In addition., the peptide has been found in animal studies to improve heart health, increase bone density, improve renal function, and possibly even fight off the effects of dementia. GHRP-2 not only helps to build muscle, but has been shown to enhance muscle structure as well[1]–[3]. It is also a strong appetite stimulant, improves heart function, boosts immune function, reduces pain perception, and benefits sleep quality[4]–[10]. GHRP-6 has been shown to protect brain tissue, enhance memory, boost wound repair, and modulate reward-seeking behavior[11]–[21].
The above list of effects demonstrates both common overlap as well as complimentary features for the peptides above. By combining a GHRH analogue and a ghrelin analogue, maximal growth hormone release is achieved. By combining all three peptides in the correct way (e.g. alternating GHRP-6 with GHRP-2 dosing), it is possible to also amplify the peptides’ secondary effects and achieve additional benefits such as enhanced bone deposition, improved brain protection, and more.
