It has been noted that testosterone may act as a pheromone all by itself and I had also made a post about this few years ago. Since Semen has a good enough concentration of testosterone (approximately 0.7 ng/ml as per this old study) it may be possible to harness your own ejaculate and "sanitize" in alcohol and with sufficient amount stored use that as your own personal pheromone spray. Its unknown what dosage per spray we need it to be effective but first lets calculate how much ejaculate and alcohol/cologne we would need to provide a decent amount per spray so we can begin to experiment. The average volume of ejaculate is 3-5 ml. Since "harvesting" is difficult lets say you can get about 2 ml of semen per ejaculate. The average concentration of testosterone in semen is 0.7 ng/ml. Therefore amount of testosterone per ejaculate is 1.4 ng contained in 2 ml of volume. Lets say you want to have a 30 ml ( 1 oz) bottle of this spray, with atleast a 2:1 ratio o
