I have been taking "one" Advanced Yohimbe-Plus a day for the past week. Do yourself a favor and heed the warning repeated throughout these reviews regarding dosage. Start with one. Don't start with three. Side effects are starting to subside, but first few days were awful. Nausea, whacked-out body temp fluctuations, anxiety, sweaty palms and feet, significant increase in heart rate, and insomnia. However, as I said, these are subsiding, and if you take one of these in the morning with breakfast, that seems to work best. Positives: Firm erections, increased libido, weight loss, etc. I'm still just doing one a day. Perhaps down the road I'll try two.
