i just started a cycle of cyp and am doing 600mg a week and was wondering if i threw in some fina and winny around week 8 till 14 would that be ok or would i waste all the gains i got from the test?the cycle would look like this.

1-11 test cyp 600mg week

8-14 fina ed at 75mg or i could do it longer depends on yalls feedback

8-14 winny at ed or eod depending on yalls input

so all help would be great!
peace
