If this is OK by you to perform, then try seeing how your underarm odor changes when you use it. Absorption will be minimal (estimates for a dpg alcohol combination put tda at about 5%), but you may still get enough to get deepending of underarm odor.
Also, if you sprayed it DIRECTLY to your underarms, not doubt you’d get a deepening of odor.
Also try spraying to the hair on top of your arms. Give that bacteria something to munch on. I think that may be the most valuable function of DHEA based products, aside from maybe a general “glow” of health.
