Sermorelin,GHRP-6,GHRP-2
A combination of growth hormone (GH) releasing peptides can lead to tremendousincreases in GH levels, but such a process generally only requires a growth hormonereleasing hormone (GHRH) analogue like sermorelin and a growth hormone secretagogue/ghrelin analogue like GHRP-2 or GHRP-6. Combining all three isn’t likely tocause a proportionally greater increase in GH hormone levels, but are other reasons toutilize such a combination.
Sermorelin is an excellent GHRH analogue with strong GH releasing action and very fewoff-target effects. in addition., the peptide has been found in animal studies to improveheart health, increase bone density, improve renal function, and possibly even fight off theeffects of dementia. GHRP-2 not only helps to build muscle, but has been shown toenhance muscle structure as well[1]-[3]. lt is also a strong appetite stimulant, improvesheart function, boosts immune function, reduces pain perception, and benefits sleepquality[4]-[10]. GHRP-6 has been shown to protect brain tissue, enhance memory, boostwound 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 thecorrect way (e.g. alternating GHRP-6 with GHRP-2 dosing), it is possible to also amplifythe peptides’ secondary effects and achieve additional benefits such as enhanced bonedeposition, improved brain protection, and more.
