it is hard to dose 20 mg by 3 since most sr9009 come in 10mg or 20 mg per tablets
can use 30 mg divided by 3 easier. and 30 mg/day is also going to be more effective
i did yk11 with lgd4033 and rad140 at the same time. burned fat and gained muscle at the same time. but you gotta prepare for such a cycle. also, don't try it if you're beginner.
