I am using hCG. I just started. All the research I have done leads me to believe that you use hCG during cycle, when shutdoen is occuring. This keeps function in the testes during the whole cycle... making pct easier. That las part. making pct easier, is why I am using it. IMO pct is just as important, if not more important, than the cycle.
But yeah, I am on my first cycle now, and I am using hCG
