SD-2 has A314 in it. This is mainly why guys show interest. They’re giving respect hits.
Women are not as easy to notice the interest of, because they don’t “speak the same language”. You notice guys responding because they “speak the language of guys” in how they express themselves.
SD-2 gives a pheromone signature that is attractive to women, mainly bisexuals from what I have observed. But women don’t always make their interest or arousal obvious. Many times I’dhave had no clue the woman I was with was becoming aroused if she hadn’t commented on it.
