You came to the rite place Bro, lots of guys here with incredible knowledge. I'm not one with a lot of knowledge of ph's. But your on the rite track with epistane and Havoc aren't real bad on your liver. I would check out the ph cycle section and find someone cycling ph's. But I'm sure somebody will chime in and give you good advice better than me. Good luck and looks as if you know what your doing physicaly by your photo.
