Yeah, I went back and checked out some of your old threads. You seem to be really trying to do this thing the right way.
So any way, to answer your 1st question; Sus is one of my personal favs. I have used it or omnas in at least 10 of my cycles and am currently on now.
I can use relatively low doses and still get the results I am looking for. with little to no sides. I am extremely hot most of the time and usually break out a little in the middle.
For me now, in the beginning, I only used 250ew and only injected once a week. Had great results, just can't be that lucky anymore.
With your stats and this being your first cycle, I would go with 500mg every week for 10-12 weeks. I would not even worry about the eod pins, just go on mon and thurs 1ml each. If it works out try eod next time. You can burn out pretty fast on those eod pins early on.
So as far as PCT - post cycle therapy - - post cycle therapy - - post cycle therapy - - post cycle therapy - - post cycle therapy - I can't advise you as I do things a little against the grain and it looks like there are a lot of good options now.
