First cycle needs advice and guidance

I AM 22 AND PLANNING TO DO MY FIRST CYCLE I WAS THINKING ABOUT TO TAKE

STACK 12 WEEKS
SUSTANON 500 MG/WEEK
NANDROLONE PHENYLPROPIONATE 400MG/WEEK
HCG 500 IU/WEEK
ANSTROZOL 0.25 MG/EOD

PCT WILL BE FOR 4 WEEKS
Clomid @ 75/50/50/50 & Nolvadex @ 40/20/20/20

I WANT TO KNOW WHEN SHOULD I START MY PCT AFTER MY LAST INJECTION OF SUSTANON AND WHEN I SHOULD STOP TAKING ANSTRZOL

BODY STATS:
HEIGHT 5'10
WEIGHT 170 LBS
BF 10%

I think for sus, you start PCT 3 weeks after last shot.
