Sermorelin is GRF(1-29) which is a short acting GHRN with a 1/2 life of 5-10 mintues. Not very good stuff. In order to get an effect it would need to be taken at high doses. What you need is Mod GRF(1-29) which is the longer acting GHRN AKA CJC-1295 without DAC.
Common dosing is 2-3 times a day, upon waking, PWO and Prebed. I would recommend that you combine this with your choice of GHRP. There is a synergistic effect when you combine them both.
