When Hexarelin is given as a subcutaneous injection, it activates the pituitary via a pulse, just like GHRP-6, and helps circulate growth hormone in the body. Unlike GHRP-6, it does not induce any hunger side effects. Hexarelin has the ability to not only raise the level of GH in the body but to also suppress somatostatin, which is the main culprit that inhibits GH from being released. This means that there will be more GH in abundance. In addition, hexarelin is the strongest GHRP available, so users should notice that desensitization can come much quicker than other GHRP’s. This makes it less ideal for long term use, but with hexarelin’s ability to raise healthy levels of IGF-1 and GH it can work perfect as a PCT tool for those coming off a synthetic GH/IGF-1 cycle. The potency of this peptide should not be underestimated and it comes with an increase in cortisol production as well as prolactin. Nothing close to what might be seen in elevated levels from steroid use, but compared to other GHRP’s it has the strongest affinity to raise cortisol/prolactin.
