A double blind study label for use in, e.g., a drug study. A first portion of the label, identifying the test drug, is coupled to a vial containing either the test drug or a placebo. The second portion of the label identifies the actual contents of the vial, along with instructions in case of an adverse reaction, but all of which is concealed by an scratch-off, opaque layer. The second portion is severed from the first portion and held by the testing agency. Thus, every participant believes he/she is taking the drug under test.
