Yohimbe bark isn't useless, per se, it's just harder to predict an effective dose, and even if you reach that dose, the side effects - which increase both with herbal preparations and higher doses thereof - may not make it worth the effort. 
L-Tyrosine is the precursor to several fight-or-flight neurotransmitters, and will give you a bigger kick from CNS stimulants like caffiene, ephedrine, yohimbine, norephedrine, etc. I get a mild buzz off of it on its own if I take megadoses (2.5-3 grams) on a very empty stomach. It also has thyroid support properties, and will help you tan more deeply.
