Aweful taste at first!
Bitter and sour flavor first and second servings.  Was about to send it back.  After the third or fourth serving the flavor changed drastically and was actually pleasant and tasty!  I think it was from settling in shipment.  So stir up your powder after you break the seal!<br /><br />I can feel the Niacin tingle within 20 minutes and the caffeine content is perfect for my use.
