Zenadyne good or bad thermogenic?

[Buffalo Joe]

I was reading about a product from Universal Nutrition called Zenadyne. it has the basics:

Ma-Huang extract 335mg
Guarana extract 910mg
White willow extract 105mg

but it also has:
Bitter orange extract (Synephrine) 85mg
plus ginger root, citrilene, L-Tyrosine, Acetyl-L-Carnitine (ACL), Mag Phosphate, Dimethylaminoethanol, and Isoflavonol.

Is this really good? I read putting a synephrine with your stack is good. What about adding Yohimbe to it?

thanks for the help.

You know what? As long as it from a known maker most burners work.
