There are two ingredients commonly referred to as "Pheromones" in body products:
1. Androstadienone, which is primarily found in male sweat.
2. Estratetraenol, which is primarily found in female sweat.

Whichever one a particular product uses isn't always found in the lable, because cosmetics are not required by law to disclose their ingredients. For best results, I imagine you would choose whichever one matches your biological sex. Any women interested in other women will react to the estratetraenol, at least in theory.

Pheromone products are just marketed as "attracting the opposite sex" because that's their primary market. It should work just as well on homos.
