I used the early muscle tech "stack" nearly 20 years ago when their stuff first came here to the US. There was something in that stuff... people around me were asking me after a week or 2 what I was "on". And my personality did change a little - I definitely became more aggressive and more of a hothead than I already was.
I didn't use much of the ECA because it was too strong for my taste - made me overly wired and unable to eat much. I sold it to a buddy for a few bucks.
I tried the other stuff again a few months later, and it wasn't the same. Between my first and second "cycle", the Muscletech stuff got mysteriously pulled from shelves everywhere for a few weeks or so. This was before the internets, or at least before they were popular.
