I am contemplating on several stacks at this moment for the fall winter time for my bulk. Here they are:

12 wks Sust
12 wks deca
last 6 wks Fina

or

12 wks sust
first 6 wks Test Prop
12 wks deca

my only question is if test prop is already in sust, is it a waste to stack them together? or will it just make the gains even greater? Just looking for a good cycle for bulk. i know its gonna be either of the two just really trying to feel the best scenario out. looking for some feedback tanks
