do i have to up my doses

[Steroider]

hi all ,

im 30 years old , 6" tall , about 115kg , my last cycle was :

1-16 Test-e 750mg/wk
1-14 EQ 600mg/wk
6-14 Tri-Tren450mg/wk

and now planning my 5th cycle

1-14 Test-e(or)cyp 800mg/wk
1-12 EQ 600mg/wk
1-12 Tren-Ac 75mg/ED
1- 5 D-Bol 60mg/ED to kick start

1st) do i have to up my test doses to 800mg/wk or its ok to go with 750mg/wk again ? in my last cycle i had some sides ( red scratchy spots al over my body bot i didnt taper the doses
2nd) can Tren be effective at 75mg/EOD ? in case saving some of my budget
3rd) anu ideas to enhance this cycle ?
4th) can i add HGH to this cycle ?

goals : gain as much as possible and cut some fat at the end of the cycle
