Hey guys. I just did my first two injections last week. I am going with 500mg Sust for the first two weeks, and then 250mg the rest of the time. This is my first cycle ever and I was a little worried about it. I had my friend shoot me up both times. It was nothing like I expected, I actually liked it. It was more of an adrenaline rush than anything else. I was just wondering when Sust usually kicks in. Is it about the 3rd week??
