The only thing that might be an indicator of pheromones in humans is a phenomenon that occurs among women:
When women are around each other for any length of time, their menstral cycles will start to coincide and, in time, will run on the same timeline.

Within the past decade, some researchers have started debating whether the nature of this occurance is caused by pheromones, marking the first and only evidence of human pheromone interaction.
