IBE sent me 2 bottles for test out, one of which fell off my fridge, landed smack dead on the bottom of the bottle, blew the top off of it, and managed to get sticky red stuff on 4 walls / ceiling / cabinets...it was such a mess that it was hilarious...but half the bottle was still good....So:
I tried the half serving so far :
For a half serving:
A little chemical tasting, but far from offending, had a hint of fruit, and a little sour to it, not bad...but they are making new flavorings for this so taste is probably pointless to discuss.
I was very pleased with the half servings impact...definitley picked me up, felt totally positive while under its spell. No crash, no jitters...its a clean clean burn
Also - when I used it I had a cold, and it cleared my sinuses up nicely for a couple hours.
