A kit for quantitative determination of protein content in a whey protein supplement, the kit consisting of:

• (1) a shaker bottle for mixing a protein supplement powder by manual shaking;
• (2) a graduated tube with markings to measure amount of protein precipitate in said whey protein supplement;
• (3) a non-graduated tube containing a protein precipitation solution wherein the protein precipitation solution contains trichloroacetic acid (TCA) in an amount of 30% w/v and ethanol in an amount of 5% to 20%;
• and
• (4) a protein measurement chart specifically calibrated for whey protein with precipitate volume in milliliters indicating corresponding amount of protein as percentage;
• wherein said kit is for quantitative determination of protein content in a whey protein supplement by a consumer in a home setting, in an environment that does not require sophisticated instruments of a laboratory, and not in a laboratory setting.
