No Dr's will approve this. He had extreme fatigue, but only did it 4 days. Have u been on the A L S T D I site. His fasticulations increased immensley, which leads me to believe it was working, as increased facis mean the muscles are trying ti repair the damaged muscle. I was told that whatever gains you get in the first cycle(8days) is probably all u will get. Wish HLes would have continued, but, it is his choice. He took the high concentrate mixture, and did not have loose stools, which most people experience.
