All I know is my son-in-law had chronic high blood pressure and was on blood pressure meds for years. After 2 months of taking Protandim, he cut his meds in half and in 3 months, he is off medication with normal blood pressure.
It also cured a rare skin disease that the doctor said there was no cure. With Protandim, it is gone!
Bottom Line: Yes, I would recommend this to a friend
