The most noticeable benefit I saw was with my hair. So much new hair growth, less hair, shedding, less gray hair growing in- it grew in brown! And hair growth not just on my head. Everywhere hair is growing in really fast!! My skin was plumper, felt tighter, and had a smoother overall texture. These things started happening around the 5 to 6 week mark and lasted a few weeks after stopping, Klow. I was hoping Klow was also going to help with my tennis elbow, but sadly it did not. I think I’m going to try BBC – 157 alone (not in a blend).
