I just started as I have read some recent research showing that supplementing with this herb can increase fat lipolysis.this article is a couple years old thoughhttp://www.ast-ss.com/articles/article.asp?AID=231
When I went to GNC last month to look around, they had Yohimbe on clearance for about $4, so I bought it. I took 2 just to see how I would react, and that stuff had me sweating while sitting in place, very speed like. I think more so then ephedra. I didn't really like the feeling so I have not taken any since then.
