Some people can tolerate ECY, most can't. I wouldn't recommend people to use it even if they could tolerate it. Both ephedrine and yohimbine basically do the same thing, although through different pathways (from a fat loss standpoint, each has their own unique properties). The rise in blood pressure from ephedrine alone is bad enough, with yohimbine in the mix, it doesn't get better.
I've used both TTA and sesamin. Both have decent literature backing them (although, yeah....rat studies mostly on the sesamin), but neither panned out as far as fat loss in the real world. You find some people who swear by them for fat loss, just like you find people who swear by Cell-Tech.....and only Cell-Tech.
