And do you feel it is worth the addition to your toolkit? I am really interested in trying many of the products that are coming to market. While I suspect that some if it is snake oil, some of it will be vastly overpriced, and a good deal of it is going to be worth evaluation.
I think that all too often we get hung up on the price of that 'bottle of water' we bought and dont assess what the manufacturer has going. Many of these things require a certain volume to remain stable. Sometimes it is placed there so that you don't lunk it up trying to ad .23 grams of material to 2.74 grams of material. They make it to the all mighty 5ml (teaspoon) mark. This is not aimed so much at us because a great many of us realize what we are getting into but for beginners and those that just don't want to be bothered you can follow the labels on may nutes and have a success. Nothing breeds success like success.
I would live to see a thread on additives. We could call it the Additive thread. But where would you put it?
