(GH?) Would this be a waste to start now?

[HELLA SWOLE]

Okay, i am doing a show next summer and i want to start GH soon to go along with my bulking to help me keep off the fat. Well, here is my dilemma. I would like to start now, but I will be leaving town for a week around thanksgiving, and then leaving again for abotu 2 weeks around X-mas time. I knwo GH takes a good 6-10wks to kick in, so would these two breaks set me back as far as noticing anything form the GH? I will be using 4iu 5 on 2 off BTW. Thanks
