How old are you?
I have ran sustanon three times and only once did I do it properly. I have learned alot from some of the vets hereand other places. You definitely need an AI, now, something like a-dex , .5mg every other day is a normal dose. Also, you need a proper PCT(post cycle), as you mentioned, Nolva and Clomid(both) is a common PCT for this cycle and doses are every day as follows:Nolva 40/40/20/20 ...Clomid 50/50/25/25....that is mgs per day for four weeks. So week one 40mg Nolva and 50mg Clomid per day.
On another note, you are on week 4 now if I am following your plan. How long do you plan to go(how long will your gear last in weeks, hopefully 10-12.
And if you wanna be 6'1" 160 you can't be bulky, by any means. Maybe lean and trim but nowhere near bulky at that height.
If you just wanna gain weight you need to be eating alot! Watch your BP as you gain though because you wanna gain 25-30 lbs on a frame and system that isnt used to that much weight. Thats almost a 25%bodyweight gain. Pretty substantial.
Some guys here may tell you to just eat alot and workout to make the gain you want. Gear is meant to help gain muscle mass and size, not just have a healthy body weight.
But you need to get the PCT and AI ASAP!!!!!!!
