I seem to respond very well to trib. I know many people do not get the best results with this herb, I guess I just happen to respond better than most. For what it is worth I have always gotten better results with the trib that is not dirt cheap, I always did well on Tribestan(2 tabs 3 x a day), Vitrix(2 tabs 3 x a day), N1-T(followed label). I also should point out that the second 2 are formulas with other ingredients but still are comprised mainly of trib. I always used these products as PCT for various "designer supps." Adadarian I did use some of the product you have from Twinlab and found it was alright but I like the three I mentioned better.
