No, it is not the closest thing to anabolic steroids.
most moomiyo that is sold in health stores is poor quality. To get the good stuff you have to go to some ancient cave and spend a good week there, looking for 1,000,000 year old bird poop.
you need to know how to use it. I don't think it will hurt you (it is non-toxic), but to get the best benefits, you need to know how to take it. Otherwise your money will go to waste.
