Sorry I don't have any scientific data. I was hoping someone in this group may have. I don't know much about srem cell activators other then they supposedly stimulate our own stem cells to regenerate. They are not stem cells but they work with our stem cells. I saw an infomercial by Joseph Christiano ND. I went to body redesigning website but didn't see studies or any meaningful reviews. So I thought I'd ask this group in case anyone has had experience with stem cell activators. I have been talking algae cal for several years. My dexascan improved significantly but still getting compression fractures. Also if you search natural stem cell activators there are foods that stimulate stem cells naturally as well as an emphasis on life style.
