Primobolan, Deca, and Dianabol cycle question

[kirobg]

Hi everyone. I am 23 years old and I weight 210 pounds. I am planing to run a cycle with Primobolan, Deca, Dianabol, Dostinex and Nolvadex. Here is how my cycle looks like:

Primobolan - 200mg a week for 12 weeks starting week 1
Deca - 400mg a week for 10 weeks starting week 1
Dianabol - 40mg ED for 4 weeks starting week 1
Dostinex - 2.5mg ED for 12 weeks starting week 1

Week 13 and 14 NOTHING

PCT Nolvadex
Week 15, 20mg ED
Week 16, 20mg ED
Week 17, 10mg ED
Week 18, 10mg ED
Week 19, 10mg ED

Please let me know if there is something wrong with it.
1. I am concerned about the PCT and the use of Dostinex. I am not sure when I have to start taking Dostinex and for how long.
2. I know that Dianabol is liver toxic, but I don't know if I have to take something along with it or not.
3. When I start my cycle, can I inject Primobolan and Deca in the same day at the same time? Does it matter when during the day I will take Dianabol?

Thank you in advance!
