there's a thread about it on the aging board. i just saw some at the health food store tonight. there was one that was around $30 that you put under your tongue and it gives you a little boost and then there's another one that costs about $120 and comes in a big bottle which i was told works great. check out the thread on the aging board if you haven't already. aren't you on the SB Diet? i'm on Day 4 and losing weight FINALLY!
