For a natural, you have a good build. You are basically at the peak of what you can be as a natural. Go read phase 1 of the bible. To advance from the stage you are at, you better let phase 1 soak in to your blood. Take a bath in it.
Then get some product in your blood, and forget about pct. How dedicated are you? You surely can get up to 220 and lose a little bit of body fat, but as soon as you get off cycle and run your "PCT" (a concept I don't know one thing about) you will gradually, but surely return to exactly where you are at unless you get back on soon enough... Yes you can go off for 4-6 weeks and not suffer too horribly.. No, you can NOT go off for 6 months.
And my suggestion is to run sustanon @ 350 mg per week along with EQ at 600 mg per week for 16 weeks. If you are having libido issues, up the sustanon to 500 mg but do not exceed 700 mg because high dose testosterone will not be conducive to the goals you have laid out, and you are doing a first cycle anyways.
After your cycle finishes, continue the sustanon, but lower it to 200 mg and run this for 4-8 weeks. Then repeat the cycle, or try something new for another 12-16 weeks. Then after you are done with this second cycle, cruise again for 4-8 weeks.
Repeat these steps for the remainder of your life, and you may one day look like a poor man's version of arnie in 1980 olympia (but not likely, and remember you have to use GH as well to even achieve poor man's version of 1980 arnie). If you are talking about looking like arnie circa 1974 olympia though, then you are whacked out of your mind.
