How much would you recommend frontloading then DIV? 500 mgs sounds about right to me, but of course I could be wrong. Oh and what is your cycling history and/or chem. expertise? Not to challenge or anything but I've gotten shit advice on this board before from someone regarding cynomel. The arguement that you are making(too much instead of too little), tells me you don't want anyone to get hurt, but I'd still like to know.
Where the hell is Big John when you need him? 
Big John is AWOL. I need to ask Ron and see where him and Hank are......
I'm not a chemist, nor have I run anything over 1G Test for any length of time (6 months).
I only use as much as I need to, still learning how different AAS affect me, like most people I would hope.
That said, I have used all the basic AAS that you guys run, and I know what combinations work best, and how to layer a cycle so everything runs smooth.
Frontloading is something that I don't recommend for newbies or even moderate users.......mainly guys who have at least 6+ cycles under their belt and know themselves and how that much Test saturation at one time will effect them. That way they'll know the sides that happen for them, and can deal.
It's really up in the air as far as if FL is beneficial to a cycle......and it depends on what else you are running as to how effective it CAN be. It'd help if you posted what you want to do......
