it's due to the fact that bsn changed their formula 3x. The old one, (before CM3) had prescription blood thinners in it. The newer one, though the addition of Beta Alanine which is fantastic, also added more "Glucose polymers". Glucose polymers is a fancy name for table sugar. Plus they added even more fillers. It took me 3 scoops to feel anything off of it, and I always ended up sick to my stomache b4 i finished my work out. The stuff's garbage and I refuse to sell it at my store.
