Looking for plain whey sample for research

[shanebee]

Is there anyway i can get a free sample (1 serving/scoop) of plain whey protein, our lab uses powered milk as part of a blocking buffer for our experiments. I was thinking that whey protein might work better but i only have chocolate flavored whey at home . Any way you guys can send me a sample of your unflavored whey (just 1 scoop) and if i works I can order a full container.
