I don't wanna diss your cycle or anything but there's no point doing Winny with 525mg Masteron/week. You won't even need the Winny at all. Masteron does everything winny does better without the joint pains. Just my 2c...
For PCT you can always use the same protocol after your cycles because you're trying to the same thing after every cycle which is keep estrogen levels down and restore natural test levels. Some okes use clomid, some use nolvadex/kessar and both will work but I prefer kessar. One box is fine, 20mg/day for 30 days or 40mg/day for a week then 20mg/day until the box is up. You'll find both are recommended but both are fine. Since you're using short esters you can start 5 days after your last shot. I don't think HCG is really necessary on a 8 week cycle but if you want to use it you should do so before you start PCT because it is suppressive. Just don't do high doses because you can damage your testes permanently. I do 250iu every 3 days starting from week 4 on all cycles (I don't do shorter than 12 weeks). Incorrect use of HCG can make you sterile so best to do some reading yourself. Good luck with da gains.
