So, I am a native Peruvian living in NY. I have consumed Maca my whole life. Energy wise, it cannot be compare to anything else, it does take some time to work, but it is with all natural supplements. Libido and sex. Well, I am almost 40 and I feel like I am in my twenties. I do exercise and eat healthy. When buying Maca, make sure it says, “Made in Peru”.
