I have been taking Cowabunga Colostrum for a few weeks now, and I have to say, it's my favorite. I have more energy after working out, and I'm not as sore afterwards. I have also noticed my hair does not shed as much on wash day, and my nails are growing like crazy. Although I would like different flavors, I like that I can put this in my yogurt, milk and water without any after taste. This is now a staple for me. I have tried a few different brands of colostrum, but for the quality, price and results I have seen and felt, I would highly recommend this product.
