HCG is like the primer to kick in your natural production of test. It isn't until you have come off of the HCG that recovery actually begins. So you want to use it before you start PCT, so that it acts like a primer, getting the engine to turn over. So figure out how early you can start your HCG to run it on cycle at 250-500iu, 2x wk, right up to 3 days before PCT starts. Then start taking the Clomid at 100mg ED for 7 days and then continue at 50mg ED for the next 14-21 days
