I got a question(s) about Yohimbine.

Being an anti-depressant as well as aphrodesiac, and supposedly (heard conlifcting reports) an MOA inhibitor as well Yohimbine HCL intrigues me.

My question is to any and all users/knowledgable ppl of Yohimbine:

If just one day one popped 10 mg's of Yohimbine HCL, would they be able to get the aphrodesiac as well as anti depressant qualities in them??

What i mean is, do you hafta use yohimbine for weeks before it begins to cause an effect, or is it noticeable within the first taking??

If its not noticeable within the first taking, would using a larger amount such as 20 mg of Yohimbine HCL make it more noticeable over a single time usage?

thanx to any bros who can help.
