I heard so much about yohimbee increasing the sexual desire in both women and men and I know first hand by me taking... I bought a bottle of that GNC brand and would squirt a dropper in her nightime glass od cherry coke, this masked the taste very well. Stirred it a little and noticed an almost immediate differnce after she drank the entire contents. I would do this maybe once or twice a weel but I noticed she was much more vocal and indusive and would even wear those sexy nighties and nipple rings I like. But she would get this look in her eyes.. that stuff definately does something.. She through it away by mistake though, never knew she had been getting it nor does she know what it is for. I have to get some more...try it for yourself.. DO NOT OVER INDUCE.. I only gave her a little over half a dropper. Yohimbee can make you sick so do not kill your lady to try and get her all horny not the whol bottle please.. a little goes a long ways...
