I don't know about vinegar in general. I use organic apple cider vinegar. I have not used it for steroid detox, but... I use to drink and eat heavy. I mean, 20 drinks every night and HUGE restaurant meals. Pot on top of that, and we know that's not always 100% clean either. I would gorge more during the holidays. At some point I got to having acid reflux, a symptom of liver intoxication. A couple tablespoons of this vinegar thing in half a glass of water upon waking up, and 2 days later I'm super-good, so I think it is fairly mighty at liver detox.
After a while of experiencing this, I got to pre-treat with it, meaning that the week before major parties I would clean my liver with the vinegar and then I could eat and drink like 12 pigs and still fell FINE. The hangovers simply didn't happen, either, and that is a sure sign of enhanced liver function. I use it all the time now.
I don't know how valuable the parallel between drinking and steroids is, but for drinking it is a major effect. Use the organic apple cider vinegar. It is inexpensive and tastes MUCH better than standard vinegar.
