Twinlab Yohimbe Fuel has changed my life altogether. I now do my gym workouts with much more enthusiasm. And the gains have been more than great. I feel highly motivated even after the workouts. My sex drive is over the roof now. All these are at the same time that my body has developed some reactions to it. My stress level has increased considerably. The libido is too much with erections becoming painful and hard. I am highly energetic in the nights that I have sleeplessness. You can get extremely paranoic so that you might get delusions that you are being watched by others which might not be the reality. I also got panic attacks after I was on the drug for over a month. Now I have learnt a lesson that I have to take the drug in moderate amounts. Plus, it is better to avoid taking the drug for a long period of time since it might damage the liver. Also, it might develop stress-related complications.
