I agree with ghettostudmuffin's post entirely. A multivitamin is all you really need. Generally speaking, most supplements are a waste of money. If anything works it usually gets banned. However, steroids obviously work, but I wouldn't call those supplements. Prohormones obviously work, since they are steroids, but could be considered a supplement I supose. Animal Flex helps make my joints feel better, so I would say it's the real deal. But you will find a number of junk products out there that come and go faster than a speeding bullet. As with anything, research the ones you want to try unless you have endless money to blow and want to find out yourself. I research what works by reading a lot of logs and reviews. But even those have to be scrutinized to some degree. I think that supplements are getting better though and real products are getting developed these days as opposed to 20 or even 10 years ago most products were just junk.
