-I am currently in My 8th week of Taking Sustanon 250 (super test) 500mg's a week and i am having great results in my chest sholders and back. My arms have gotten noticably bigger people have been telling me but i feel like i am not getting as good as pump with my bi's and tri's as i am with all the other areas i have listed.
