Fifteen years ago, Twin Labs made Amino Fuel in a liquid form. At that time, the label stated it was an "enzymatic digest of lactalbumin and whey". When I checked it again earlier this year, the label had changed to "gelatin". Was it always this crap? Is there a quality liquid that doesn't need refrigeration? I am unable to carry a cooler on my job, and would like to have a 20 or 30 gram snack 2-3 times per day.
