dylan is right IMO.
it is a myth that proviron can be used as an AI. maybe for someone who isn't juicing, but for someone running test it won't do anything at all to help with estrogen and even if it did why would you want to stack 2 AI's together in your pct? makes no sense. although proviron isn't anabolic, it is still androgenic and the body will still recognize it in the body and it will suppress you which isn't a what you want to deal with in PCT. i suggest you do more research on what proviron is.
also read the sticky's above and do more research on AAS, PCT, and individual AAS. good idea throwing out the deca so you have done some research but more is needed here.
also since you are an ex runner i suggest putting more muscle mass on before juicing as well. 160 is pretty light even at your height
