I just want to add, not directed at OP, but if I can pass on some advice to anyone who reads this looking to stack a bunch of stims, bc these threads always come up: How much extra benefit do you think stacking stims will really give you?
Do you think adding Y onto EC will make enough of a difference to risk your health? I say don't open doors you haven't even come to yet. Start by changing something in your diet + training first, as the problem usually lies there a majority of the time, before you try to use supps to band-aid a problem. Also if you need more than ECA(if you aren't looking to get to 5% BF), or need to get jacked up on stims to workout, then I say look at your training and well god bless hahaha........
.......I guess what I'm trying to say is don't go chasing waterfalls, just stick to the rivers and the lakes that you're used to. I know that you're gonna have it your way or nothing at all, but I think you're moving too fast - Dorian Yates
