Hey guys,

I am currently trying to put together a supp stack to burn fat while preserving muscle and it seems like the ECA stack is the most tried and true so I thought I'd give it shot. I'm confused as to the current legal state of products claiming to have ECA in them. I thought products with ECA were illegal and that I'd have to put this stack together one ingredient at a time. While searching the web for info regarding ECA stacks I found numerous products and whole websites dedicated to selling ECA, are these legit? I would love some product recommendations. I am already a lean person, but want to burn up the remaining fat around mid section. Also I am very tolerant to stims but would is this stack okay for someone doing HIIT or is this too much stress on the heart? Any advice would be greatly appreciated. Thanks!
