Unfortunately there is really no one way to run it. I personally like to run it how I said previously (250iu's e3d then give it a little blast 1000-1500iu's 1x or 2x before you discontinue your anabolics) but again, there is no set way. I asked my doc about this and he said "Shit, as long as you used it... Most people don't even know about it".
I really recommend a conservative approach and using it during the cycle in order to prevent tremendous atrophy. I like to discontinue it about 5-7 days before post cycle therapy (pct) in order to allow most of the Human Chorionic Gonadotropin (HCG) to leave my system and have a smooth transition into post cycle therapy (pct).
Again, I'm not doctor and I don't know if I would recommend the old school Human Chorionic Gonadotropin (HCG) protocol, but I know a lot of people who have had success with it. I also know a lot of people who have been successful using it during their cycles. I go with a semi-hybrid which has been successful for me.
