PheroStrong Pheromone By Night For Men.

By Night For Men is one of PheroStrong's fresh masculine scents, grapefruit and mandarin over marine notes and warm woods, in a small, inexpensive dropper sample.

Same story as the rest of the European range: no specific compounds are named, so this reads as a pleasant fresh fragrance with a pheromone label rather than a potent pheromone product. As a 1ml it's a cheap way to try the scent. If you want disclosed, community-tested pheromones, you're shopping the wrong brand.
