…you can now compare the science that’s behind the claims, unless the claims others make are for undisclosed active ingredients that somehow cause this affect on behavior (e.g., increased affection).
The honeybee is a model organism for understanding the epigenetic link from food odors and social odors to neural networks of the mammalian brain, which ultimately determine human behavior.
There is no direct effect of non-olfactory/pheromonal sensory input of the environment that would explain gene activation and the intracellular interactions in neurons that might result in de novo gene expression, which is why the most likely driving force for increased primate intelligence appears to be odors associated with nutrition and pheromones associated with socialization.
Their results exemplify how olfactory/pheromonal conditioning of responses paired with with other sensory input occurs.
Similarities and differences between food odors and pheromones help to clarify how human pheromones work with an example of an experiment and results that show a mixture of two chemicals influences behavior.
Food odors and social odors influence the same basic neurophysiological mechanism (i.e., the GnRH pulse), which allows them to alter the gene-cell-tissue-organ-organ system pathway which links them to hormones and behavior.
