Greatings, Spain! Wonderful country! Being that this is your first cycle, you want to keep it simple. If you were to run a 400mg test only cycle, you would do fine, but I dont think that adding 400mg EQ is going to hurt anything. I wouldn't worry about adding primo on top of that at this point. Save stacking new and different compounds for future cycles. As for the HCG, it isn't needed, but adding it is only going to help your recovery and help your maintain your gains when you come off. It is well worth the addition, IMO, for any cycle. If you run test and EQ, you will need to wait about 3 wks until you start your PCT. You an contunie to run your HCG at that time, up to 3 days before PCT starts.
