I have two bottles of the 500 mgs with selenium. One is unopened and one has 20 left. Maybe more This is kind if like AHCC. I couldn't take it due to gastric distress but I have gut issues and a lot of things give me gut issues. If someone wants these you can have them. I would like to get reimbursed for postage which will be about $5.25. This could cure you! Lol.
