Yeah I'd generally say the same. Although if you were not a coffee drinker or are relatively inexperinced with caffeine 300mgs in one drink is quite a bit and the side effects with caffeine, yohimbe amplify each other. Personally I would never take any of that shit and any doctor in the know would tell you not to mix them. But to each his own funeral...
It's a little shortsighted that the article didn't take the yohimbe into account at all.
I doubt the tyrosine does a damn thing though
