ecy being : ephedrine, caffeine, and yohimbine.

Im currently using this, only issue is the nausea I get from the yohimbine when I forget to eat. Strong hunger suppression considering lately I have been hungry 24/7.

Now to my main question, how are the results on brown adipose tissue? I have searched and have yet to fine a definitive response since most people quit using it.
Would it be a better stack to target brown adipose if I removed the yohimbine and added in raspberry ketones?
