Yes, the bars are still in the works. I think they were delayed a bit because Tim wanted to get the new Methoxy-7, Surge and T2 out first. Tim wants to do bars, but bars are sort of "old school" in his mind and he's always more excited about bringing new stuff to the market, like MAG-10. (Now THAT my friends is something to get jacked about. Seriously. Read the Strasseroids column this Friday for info.) Still, the protein bars will come out as far as I know. Sorry, not certain on a release date.
I'm not sure about new flavors of Advanced Protein or Grow!, but if Biotest does come out with a new flavor in the future, I'm sure it will be strawberry since that's what most people are asking for. (Until then, try dropping a couple of fresh or frozen strawberries into a vanilla AP shake and blend. Good stuff! And fresh strawberries aren't too bad when it comes to carbs either.)
Tim will provide more details on Grow! and Nandrosol this Friday. I think the info will be in the Reader Mail section.
