Clinical dosage
Origin
NaturalYohimbine is extracted from the bark of the yohimbe tree (Pausinystalia yohimbe), native to West Africa. It has been used for centuries in traditional African medicine.
Safety
Yohimbine is a potent ingredient that must be dosed carefully. Side effects like increased heart rate, anxiety, and sweating are more common than with other pre-workout ingredients. Always start with a low dose (2.5mg). Don't use with heart problems or anxiety disorders.
For comparison
Yohimbine is one of the few fat burners with actual scientific evidence. It works by blocking alpha-2 receptors, helping your body release fat more easily, especially from stubborn areas like belly and hips.
Dosage by weight and gender
The effective yohimbine dose for fat burning is 0.2mg per kg body weight (Ostojic, 2006). For someone weighing 70kg that's 14mg, for 90kg it's 18mg. Always start with 2.5mg to test your tolerance and build up slowly. Women may be more sensitive to side effects, start with an even lower dose. Take it on an empty stomach, insulin blocks the effect.
