I have read a lot about Trib and I have taken it about six differant times. I think the key is quality. I have taken sevaral brands and only one stacks up to the claims. I am 32 and I love the stuff but was pissed off when I tried a differnat brand and wasted money. Trying to save a buck is not the best way to go when buying Trib. There are so many people that try and market it but only a few that are worth it.
