I now have three bottles of SP Musk Oil. Two of the bottles say, \"with pheromones\", and the other one says, \"with androstenol\". I also have the SP Vanilla and Citrus oil, and they both say, \"with androstenol\". Are there any differences between the solutions in the bottles? I also notice that the solution color is different between the SPMO bottles (clear vs. yellowish).
