Questions about T400

[umittt]

Hi my friends . I got a few questions about T400 testosteron (100 mg each enantad, cypionat, decodonat,isocaproate).

1- I am on the last week on my 12 weeks t400 ,tren enantad (400 mg/w) masteron (400/w) cycle. When i have to start pct?

2- After this cycle i want to make a cycle with only tren acetad and testosteron. Can i use tren acetad with this T400 or i have to buy propionate? (I like this t400 because this is cheaper than propionate)
