I just wanted to add my experiences. I went into four lows on retest with ARL and stayed there for over a year. I had a lot of trouble with the supplements as they caused more stomach issues and made me very sensitive to everything (food, products etc). I improved by treating parasites, infections and changing my diet but I only felt well when I did not take the four lows supplements. I ended up in a low four lows pattern and was told I needed to take even more paramin to get out.
I decided to switch to TEI and was placed on their fast four supplement program. The supplements felt right to me and I was improving everyday. After 3 months on the supplements my recent retest showed I was out of four lows.
