Yohimbe is an attractive supplement for bodybuilders in that it will help you in three key areas.  It is useful for better pumps in your muscles when working out, helping in getting rid of stubborn bodyfat, and as a thermogenic extender.  As was stated earlier in the article, it is used for keeping the blood in the penis for treating impotence, it can also be of benefit for bodybuilding in that it helps promote a better pump in your muscles as well from the dilation of peripheral blood vessels in your body.   This could be of particular benefit for increasing vascularity in the body as well.    This supplement is also particularly effective in cutting lower bodyfat in both men and women as well.  The lower body has a higher number of the alpha-2 receptors, especially in women.  These A2 receptors cause the body to hold onto fat.   Yohimbe, since it is an alpha-2 andrenergic antagonist, really helps you fight the lower fat problems by being an alpha receptor blocker.  You can almost draw a comparison to how nolvadex works by blocking estrogen from reaching the receptors in the body thereby reducing/eliminating the chance of gyno.  In men these A2 receptors as most prevalent in the belly and love handles and in women in the calves, thighs, and buttocks.  This alpha-2 blocking effect helps the body to release stubborn fat deposits.  On the flip side, your body will try to fight this eventually by just producing more of the alpha receptors.   I am sure that this would make it an attractive product for just this reason alone.  In most individuals, the fat in these areas is the hardest to lose on your body.  The third reason for taking yohimbe is that it helps to extend the effectiveness of other proven thermogenic supplements.    Products like Ripped Fuel, Thermodrine, the highly touted E/C/A stack, as well as clenbuterol have a limited effective period in the body.   Ripped Fuel, Thermodrine, and the proven E/C/A have an effective period of 3-4 weeks at a time and clenbuterol is really only effective for about 2 weeks at a time before these supplements/drugs quit working or just require excessive dosages to do so.  After continuous use of these products for a length of time, the body downregulates the beta-2 receptors.  This in turn also down regulates the alpha-2 receptor as well.   Well, since yohimbe is a potent alpha (A2) receptor antagonist, it then blocks these A2 receptors making the thermogenic supplements again effective for a longer time period.  This entension of effectiveness is not indefinite.  You might want to use the yohimbe for these extension purposes for an addtional 3-4 weeks and then cycle off the supplements to allow your body to again normalize.  After 4-6 weeks off of these supplements, you can again go on them and extend their effectiveness when they start to crap out with yohimbe
