you can start running hcg as early as week one of your cycle. i would start no later than around 4 wks in, using this method. you can continue up to a couple to 3 days before you begin PCT. if you have enough, i would consider using a couple of larger doses in the last wk before PCT, say 1000iu. continue using your AI as you take the HCG after your last shot of test.
i'm not a big believer in front loading gear. it seems to increase the side effects for me and doesnt seem to kick the gear in much faster. i know it looks good on paper, but in my experience, it is waste of gear. if you are using sust and eq, the fast acting esters of the sust should have you feeling "on" in a shorter period of time while you wait for the EQ to take effect
