Hexarelin is a Growth Hormone releasing peptide (GHRP). Hexarelin stimulates the Pituitary gland and hypothalamus and increases the output of Growth hormone. How it actually works is not fully understood due to it being different than the other GHRP’s (structure of the peptide). GHRPs’ release growth hormone, you can expect higher levels of IGF-1 in your body, which comes with a lot of benefits. These benefits include increased muscle gain, more muscle fibers, rapid fat loss, faster healing abilities and stronger bones just to name a few. Hexarelin is the strongest GHRP and is not to be underestimated as it is extremely beneficial.
