Not a good idea for lots of reason.
You do not have any aromatising compounds, so to say that you will use proviron as an AI shows that you do not understand the compounds that you are using. Also proviron is not an 'anti estrogen'
Anavar only will trash your lipids, shut you down to some extent and possibly tank your estrogen and give you very little in terms of gains.
If you want to run oral's only then use a compound that converts to estrogen.
I wouldn't recommend an oral only cycle, results are going to be underwhelming and they are far harsher on your system then injectable testosterone.
