when to end letro?

[Kdog@usi]

I am going to run tren and prop this winter so I was planning on using letro and l-dex durring the tren part, but when should I stop the letro usage, and maybe start nolva?
tren weeks 1-8
prop weeks 1-12

a-dex or letro, doesn't help with tren sides, use B-6

I am sorry I was under the impression that letro would eliminate estrogen, thus imairing the progestin's ability to cause gyno? I was going to use ldex just for insurance. If I were to run b-6 would 200mg/d be good? also should I run nolva with prop or would ldex be fine to protect. I think I might be a bit sensitive to gyno.
thanks
