1 milligram per milliliter is best for the RONE; I don\'t know how well this mixes with OL, but trust the perfumer\'s nose in this regard. Two studies of college women\'s response to 1mg/ml RONE provided the best indication that I had the right concentration, but I have also spent about 8 years trying different concentrations on different people--usually large groups (e.g., the audience at my scientific presentations).
2 mg/ml was aversive to most women and mildly annoying to most men. 1 mg/ml was almost always pleasant to women, and many of the men. Also, I tried both propylene glycol and mineral oil as unscented bases--both were equally well accepted, but the RONE dissolves best in mineral oil.
Since OL is generally considered both musky and pleasant by men and women, it\'s concentration is not so critical in the mix. The perfumer got it right, in any case, as he did with the musky-smelling carrier.
Overall, I did enough experimentation to at least attempt to get a \"use\" patent on the androsterone, but that would have added to the product cost, as well as added time to product release. As is generally agreed to in this pheromone, it\'s best to get the product out, and see how others report its effectiveness--as we will soon see in this forum.
