The Blood Type / Pheromone Connection?

In the study above that is nanograms per microliter of fresh aprocrine secretions. The secretions were induced by adrenaline injection. The highest amount produced by male subjects was 30 microliters.

Armpit odor is caused by hexanoic acids that are extememly powerful like copulins. Odorless precursors are carried in fresh apocrine by the apolipoprotein D carrier. Bacterial enzymes release the precursors. The contribution of -enone to body odor is negligible.

However, a human lipocalin, apolipoprotein D, was recently found expressed in apocrine glands, and was shown to bind the axillary odorant, E-3-methyl-2-hexenoic acid (E-3M2H) (Zeng et al., Proc. Nat’l Acad. Sci. (USA) 93:6626 (1996)).

E3M2H I agree sounds interesting being in greater concentration, it would be interesting to see any effects on others tried solo, and contributes to the body odor.

E3M2H is the primary odor. Primary.

A 2006 study by Japanese scientists seems to dispute the claim of the lack of body odor among Asians. From studies done in the 1980s and 90s, scientists believed that armpit odor came from volatile steroids (androstenol, androstenone, and androstandienone), which have musky and urinary odors, and isovaleric acid, having an acidic odor. In the 1990s further research showed these odors were caused by linear saturated and linear unsaturated, and branched saturated and branched unsaturated C6 C11 fatty acids, particularly trans-3-methyl-2-hexenoic acid (IUPAC name: (E)-3-Methylhex-2-enoic acid, or E3M2H for short). So this is the compound researched in this study, “Individual Comparisons of the Levels of (E)-3-Methyl-2-Hexenoic Acid, an Axillary Odor Related Compound, in Japanese [people].”

This is the teacher’s manual (2014) from the American Chemical Society:
This is the science of human odor taught in the college classroom. These are the facts as we know them in 2018 vs. 1998 or 2005.

*While I don’t know the future of Androtics or this board, my further paticipation, such as it is, will always be founded in the best facts I can find. Imperfect. That is all we have beyond guesses. My tests are to try to identify what molecules might work at approx. 500 mcg for poss use in A314 etc. Put some drops of pure -enone in cologne. I think it might do just as well in blind tests as any more complex mix. Some women love it, some will punch you. *
