When to Stop HCG on Prop?

Would greatly appreciate some advice on this? Ive read general suggestions here and there ranging anything from on the last pin of test to a week or two before pct. Being that im doing prop and injecting eod, my last test injection would be 3-4 days before pct so how should i go about doing my last shot of hcg?

If i do my last shot of hcg a week before pct then i would still have a shot of test left after finishing hcg? Very confused here, help me out guys?
