Clomid, Clenbuterol, Proviron...?

CLOMID:
Does Clomid give water retenction? does it result in a higher body fat %?
If so what can i do to reduce this effect? is Proviron useful?
CLENBUTEROL & PROVIRON(mesterolone):
Is it true that taking clenbuterol magnifies the effect AAS if taken simultaneously?
I read Clen helps keeping gains after AAS usage is discontinued...what if you start taking Clomid while you're still using Clen?
Is Proviron useful for the same purpose (keeping gains after AAS is discontinued) and what if used with clomid?

PLEASE HELP!
