little help?

[hugoboss]

I am 6'7", 110kgs, about 10%bf, done one cycle previously test e 500mgs per week for 12 weeks.

Next cycle:

1-12 test C 500mgs

1-10 deca 400mgs

I was planning on runnin letro at .25mgs eod thoughout along with caber.

Question is can i substitute aromasin for the letro as i have excess aromasin on hand. If yes how many mgs would i require?
I have had some gyno previously which i was able to get rid of with letro.

Thanks
