you can run both at once if you want but if i had to choose one, I think the winnys a way better bang for hte buck. Will make you much sharper and is stronger mg for mg. Remember anavar at higher doses isnt as easy on your system as people think. Personally, I would try to run at least 250/mg a week with either of those compounds and it will still be pretty easy on your system. Only other reason to really run var over winny would be concern of hairloss. If your set on it you can run anavar at 6-8 weeks 50-60mg a day and still do alright. Same with the win. At least a little test will greatly increase the cycle overall, both how you feel and how you will gain. IT will still be pretty mild on your system and youll recover from fairly easily with proper pct. For a nice mild cycle I would run:
1-10 test e 250mg/wk
5-10 winny 50mg ED
proper PCT
If you need an AI, keep it light, and dont overdo it. Much isnt needed with such a conservative dose of T.
