Is clen effective?

[MazPsl]

I've been gymcelling for a couple of years now, I have decent gains but want too leanmaxx. Some sources say clen will just increase my daily cal expenditure by 200 cals and do nothing useful. Other sources say it is slightly anabolic as well as helping you burn calories. Is clen actually helpful or is it cope?
