A year ago I went through about 40 cc of TT sus and got jack shit from it. I think I gained about 5 pounds. So, I won't buy that shit again. For whatever reason, I have noticed some TT works, and some doesn't. So, that's why I don't like to use it. It's kinda like flipping a coin. Sometimes it will land on heads for you, and other times you land on your ass. Perhaps Ichabod's observations will help you in determining if you should use their sus or not. I haven't a clue what the batch number on mine were, but given Ichabod's findings I am willing to bet they were above #18.
