My vote.......Unipro Perfect Protein. It's also lactose-free

"Perfect Protein Highest Biological Value Whey Protein Advanced Cross Flow Micro-Filtration Process (CFM) Lactose Free and Fat-Free Unipro's Perfect Protein has the highest biological value of any known naturally occurring protein. It contains very high branched chain amino acid (BCAA) levels (25% of the protein is composed of BCAAs) and contains easy to absorb forms of amino acids (di- and tri -peptides) which support nitrogen retention."
