i would frontload 1000mg on day 1, 1000mg on day 8, and 500mg every week after that for 8 weeks. if possible stack with 30mg of dbol or 50mg anadrol every day for 2 weeks on, 2 weeks off.
add milk thistle and ala anytime you're taking orals.
If you're going to front load with sus, it seems like it would better to space the shots out over the week. Right now I'm two weeks in to front loading 1250mg per week for three weeks then cutting back to 750mg for the rest of the cycle.
Depends on your cycle history. Is this is your 1st or 12th cycle? (I don't know) I could tell you the best way is to take 1 shot ed, or maybe 1 every 5 days. But starting off with your stats and cycle history would be beneficial here...
I'm considering the same cycle...that is, a sust only cycle and looking for around 15lbs (20 seems like a lot).
I have never done a cycle. I'm 5'8", around 190lbs, 12% bdf. I've got the workout and diet down, but I'm reaching (or have reached) my genetic potential. Gains are getting very hard to come by now.
I have never frontoaded, but I will on my next sus cycle. I have used sus @ 500 mg/wk and gained between 13 and 15 pounds. That cycle was 8 wks and two shots a week. I would not do less than this even if it is your first cycle.
