You haven't given any indication as to your goals, lifting history or current condition so i don't know if this is suitable for you or not but its up to you what you do anyway
With the stock you have i would say that this is the best cycle that you could run;
wk 1-10 500mg test e
wk 1-10 400mg tren e
wk 1-6 dbol 50mg ED
That's a solid cycle.
I think this uses all of the test and tren that you have and you don't need to run dbol any higher than this. Run dbol anywhere from 4-6 weeks its up to you.
I don't think you have enough EQ to make it worthwhile adding it. I'd want to run it at 600mg minimum for 12 weeks really and you don't need to add in two new injectables at once.
I wouldn't run dbol running into PCT. This can work well with some orals but i don't think it will make the best use of dbol, especially in a cycle using longer esters.
Arimidex or aromasin during the cycle and tapered into PCT.
HCG during cycle can be used
You might want caber on hand but if you control estrogen it probably won't be needed.
Nolvadex for 6 weeks for PCT 20/20/20/20/10/10 starting two weeks after last injection.
*if you can get more test and tren you could extend to 12-16 weeks. I think 12 would be fine - Tren can get worse in terms of sides the longer you run it and will damage lipids.
