It's technically not illegal. OL discontinued it, but it doesn't make sense to me. They brought it back for a short while and then decided to stop producing it in the US a second time. It's perfectly legal to use and sell in the United States and is wildly and extremely popular with an amazing sales potential. Sorry to go off but it just seems stupid to me to not sell it while you can. It's one of the only PH/DS products that for me caused almost zero side effects and I could run it for 12 weeks, get blood work and have my liver enzymes only slightly elevated. It may not work that way for everyone but it does for me and I have the blood work to prove it. I can't really say I know any other product in its category that works so well without being harsh on my liver.
