I’ve been using 6 grams (8 capsules) of Organic Premium Peruvian Maca from The Maca Team and I noticed a huge boost in libido after only 2 weeks. I’ve been on it for 6 weeks now (I take 8 capsule as soon as I wake up) and the effects are very noticeable. I went with this companies Maca because it is a blend of Red, Yellow, and Black maca. I highly recommend it
