Im going to start a 18 week off season cycle and go right into a contest pre

I have been on the dark side for about 2 years and have fared well in comps.I leave my supplements up to my nutrition coach

but we are trying something different this year and i need to tweak a few things

the first 10 weeks i will be doing 600 of test eth and
dbol(not sure if i can stay on dbol for the full 10)

the next 8 will switch to sust 500 and deca 300

i will then go to a test prop and maybe winny during the 12 weeks of contest prep with a bit of var at the end. now i didnt list the pct's. Also my contest prep might be different. I will be working with palumbo for my diet during that time.

The 18 weeks is pretty mild but is it ok?
