Deca should be ran longer than 6 weeks, seriously no point running it any less than 10, 12 is best. I suggest running Deca till 12, so run Test till 14. Add Winstrol at 8 weeks if you want to run it for 6 and continue till 14. Or you could add it at 10 weeks and run it for 4, till 14. Run Milk Thistle for the entire time you're running Winstrol.
Start PCT 2 weeks after your last Test E dose. And run Clen during PCT. 2 on 2 off is not the most effective way or running Clen. Run it for you entire PCT (4-6 weeks) and for another 2-4 weeks. So 6-8 weeks of Clen.
