I've been doing 250mg/week sustanon for 6 weeks and I have to concur, low dose is good. I'm almost back up to my all time high weight, making good strength gains and my bf is dropping. Plus no bacne! Definitely not as horny as on higher doses but I know in the long run I'll be very happy to have gone back down to sane doses. Probably going to throw in 300mg/week deca in a few weeks to bulk 10weeks.. i LOVE DECA! Past deca/test was test-e at 750mg/week, deca at 500-600/week.
Of course, quality of gear probably has something to do with what I'm seeing, I guess the 50mL jugs I was once able to get were, not bunk, but perhaps quite underdosed... Not sure since I'm seeing gains and fewer sides.
