I cant comment on the HCG as I have read a lot of conflicting/mixed things on it.
As far as the 2 weeks inbetween, I may be wrong but wouldnt you want to start 10 days after with that stack?
Also, are you going to be doing anything to help raise your t-levels back to normal with your PCT? Ive always recommended some sort of OTC t-booster to use with the PCT. My favorite is Tropinol and I also use Intimidate for the NMDAA factor.
Hope this helps.
