Front loading used to be huge. Really, it just comes from an impatience, in my opinion. That being said, I've ALWAYS frontloaded. Adding an oral in the beginning really helps things out. The problem with the standard "cycle" is that by the time the blood levels really get going, you have a few weeks, and it's time to come off. Hence the frontloading, adding orals in the beginning, etc. IMO, if you are going to get the best bang for your buck, stay on!
