Illuminati, what would say are the key compounds to have in a regime pre-contest?
Also, do you like clen or ephedra better?
Hmmm Depends how far out from comp were staring prep & there bodyfat level.
The Below - Would Be A Good Array To Pick & Choose From.
Comes down to cost & availability.
I've know some come in great contest condition using 
Sust / mast / GH.
Test 
Tren a
Mast DiProp
Anadrol
Winstrol
Halotestin if can get decent quality - have used this in a last couple of years
Proviron
Primobolan as above for Halotestin 
GH
Clenbuterol 
Insulin 
T3 in small doses & t4
Caffeine
Aspirin
Aromasin / arimidex 
Not all of the above at once & Various combinations of them.
Plus Vits & mins + Good Food + Rest + Mental Attitude + ETC.
I Really do not like to give out a Blanket approach.
