When to Start PCT?

I ran 800mg of test entanathe for 4 weeks and then ran 800mg for another 4 weeks of a multi-ester of
Test cypionate 135mg
Test deconate 135mg
Phenyl propionate 35mg
Test propionate 25mg
Test acetate 20mg
I’m wondering how many days after my last pin should I take my PCT? What my dosage should be? Nolvadex or clomid ?

Usually 2 weeks is the general time frame after last pin
