Characterization of Armpit Odors

More information: 
What terms are used by smell testers to characterize the odor components? I haven't used deodorant/antiperspirant for over 20 years and notice my odor can smell peppery, like celery, or cumin. I think it would rate >0 on your +-8 odor scale. Also, it might have been fun if you asked the participants to rate their own smell and compare it to the experts scores. Any diet correlations? Any genetic predispositions or correlations? Also, a comment about your twin experiment... it's possible the transplant works on others. Are you assuming the transplant will fail 100% because it failed on the non-twin subject?
