that is not how you administer hcg. do 500ius ed for 10 days straight or in most cases until testes are brought back to size. most likely with winstrol you will not need hcg because i doubt your testes will shrink. clomid is a must if you don't have nolvadex. i prefer it to nolva anyway. run 50mg ed for 2-3 weeks depending on how you feel.
one day after your last winny shot but you can start hcg while on if you want. i use it at the end of the cycle and bring my testes to size then use clomid itself. arimidex is not that important for pct unless you used test
hcg if you have shrinkage and clomid/sustain alpha from PP would be a good PCT for winny. no need for a strong AI such as anastrozole winny doesnt aromatize it would drive your estro levels too low
