Clen and PCT

[jchh]

Hey guys I will be starting my first cycle Sept.1st:
30mg D-bol e.d/500mg Sust weekly

I will be starting PCT of Nolva and Clomid 3 weeks after my last injection
I also have clen on hand for my PCT in case I need an extra boost post cycle(normally just clean the diet up and add pm cardio/however i have a show coming shortly after my pct) I was wondering Should I start the Clen imediatly after my last injection or should I wait untill I start PCT?

thanks guys
