Yohimbine is an alkaloid found naturally in pausinystalia yohimbe, or Yohimbe. The main active chemical present in yohimbe bark is yohimbine HCl (indole alkaloid). A lot of yohimbine is sold just as yohimbe bark extract, but the levels can vary greatly and sometime have minimal effects. Yohimbine primarily works by blocking alpha 2 receptors in the adrenal complex, thus getting more use out of your body's own adrenaline. It is also an adrenal stimulant causing more production of norepinephrine. There are some positive functions that come out of this supplement that could drastically help some people. Here are a few:
Yohimbine can be used to assist fat loss while on a good program because it enhances the use of norepinephrine, or NE, and blocks alpha 2 receptors which inhibit fat loss. By increasing NE and blocking alpha 2 receptors fat loss becomes easier, especially burning of the Beta fat cells. These receptors are found in the fat that stores in different places on the body due to a persons gender. In males it helps burn more abdominal fat and in women it will help burn more hip and thigh fat.
Alpha 2 receptors are also known to block peripheral blood flow which can dramatically prevent fat loss. Since yohimbine blocks these receptors it becomes easier to dilate the blood vessels and get blood to the hard to burn adipose tissue. This also allows for more blood to get to the muscles which will enhance recovery and 'pumps' during workouts.
When yohimbine blocks the alpha 2 receptors it allows the chambers of the penis to relax and allow more blood in AND also helps prevent that blood from leaving. Yohimbine has been used in prescription drugs for impotency, infertility, and other orgasmic dysfunction. Its effects are proven to last up to 5 hours after initial consumption.
These are very great effects that I'm sure no man would mind to have boosted. Yohimbine is sold very cheap and does not require a very high dosage to have good effects(usually taken 2.5-8mgs). I've heard that taking one miligram per 10lbs of lean body mass while eating low carbohydrate is very effective to burn fat. Be sure not go to over the recommended dosage because some side effects could include rapid heart rate, high blood pressure, over stimulation, and insomnia and/or sleeplessness. Try it out and I'm sure you will be hooked like I am!
