dbol/slin, Sust or Test, and cycle ?'s

[Big Dog]

I'm currently using GH and will continue for a few more months. I want to put size on. I'm 6ft, 220lbs. approx. 17%BF Cycled on/off for 5 yrs.

Here are my questions: Test E. or Sust. ? I have both. I know Sust. is shot
more frequently especially for the fist couple of weeks.

I heard using dbol and Slin together can be difficult
with blood sugar. Why?

Please critique my cycle.

I was looking at something like this:

750mg of Test or Sust. per wk 1-16
400mg Tren depot per wk 3-14
50mg Dbol ED wks 1-6
50mg Win V ED wks 10-16
300mg of Tren Ace wks 11-15
GH 7-8iu 3X a wk (sides pending) throughout with Slin 4-10iu 3X a wk (4 wks on and off)

Thanks for the input and critiques!
