Tachycardia is a resting heart rate above 100 bpm.
Yohimbine would be used on an as needed basis for libido/energy.
Im not a total yohimbine hater. I dont mind it topically.
Dude listen to this guy. I'm so with you nate. Yohimbine, to me, has more cons than pro. Like 8.5mg gets me going pretty good, 10mg+ I'm fcked cuz I know I'm going to hit that anxiety/tension soon. I don't what it is about it. This is kind of embarassing but whenever I take yohimbine, it'll definitely get me hard but my sack sometimes just flattens up, I hate it. I mean it raises you libido for sure, but for some reason it shrinks my scrotum. I don't get how it's a vasodilator; if anything shouldn't it drop my sack to my knees if it's vasodilator. I'm assuming we (males) don't have the same blood vessels in the sack like the rest of our body. For my sack, it has a vasoconstriction type effect.
Oh and if the anxiety isn't bad enough, I'm sure the heart palpitations, dizziness, and headache will get you. I can honestly say EC is a better burner; more pros than cons. And if you dose smart enough, you'll hardly run into the cons. If you want an alternate, I highly suggest AlphaBurn. I wasn't really skept going into because I know how hard yohimbine is, so I don't see why I'd suspect anything really negative. I have dosed up to 2 at a time and it's perfect. I couldn't believe how well it worked, especially in the heart rate/pressure area. It really didn't increase that much, definitely not as bad as yohimbine hcl, although I wouldn't recommend more than 2 at a time; works great on an empty stomach. And no anxiety on AlphaBurn whatsoever, it's seriously awesome. Oh and the libido department is for sure on par with yohimbine.
Like dude said, and again totally agreed, as a topical it's fckin excellent. All the effects of fat burn-age without the systemic side effects. It doesn't stimulate your energy (at least I barely noticed it) but it stimulates energy (lipolysis) in the applied area for sure.
All the $hit you were facing, I'd be confident enough to say it was the yohimbine talking. How many mg were you taking btw?
