I purchased a bottle of plant IQ Organics 450 mg tincture in mint flavor and started to notice a difference within one week of daily use. I felt energized, more vibrant, and ready to start the day running! Also, the tincture did not have the plant-like flavor so many other hemp products seem to have. Instead, it tasted minty and refreshing. I placed a few drops directly under my tongue and within an hour I could feel a difference.
