Nice vitality boost!
I've been taking this superfood for close to a month now and have noticed the energizing and performance-enhancing effects almost immediately. I'm an athlete and this has helped me with endurance, stamina and increased muscle mass. The only thing I'd caution is that people who have a tendency to be agitated and tense should really avoid this, as black maca is very yang in energy from an Eastern Medicine perspective. For those people, I'd recommend the tri-color one for a more balancing effect.
