I've taken the EC (no A) stack many times before with great success yet I've noticed it can have some severe effects on my mood. Most noticeabley, it makes me very irritable and can also make me VERY angry at the dumbest situations. I've made the mistake of taking it before I went out to the bar one night, well let's just say it made me not like alot of people.
I've been looking into stacking it with L-Tyrosine and L-Tryptophan and Vitamin B6(to help the metabolism of the Tyrosine). I've read that the Tyrosine can help immensely with the mood swings ECA can cause, and I've also read that tryptophan at low doses can help as well when stacked with the tyrosine.
Just looking for any first hand experiences with the above from my fellow T-Nationers.
