I have no idea if P74 is a female pheromone. It adds an attractive quality so it’s a welcome addition to my mixes.
Liquid sunshine mixes are variants of IShine and I use that sometimes. I use other mixes which contain the primary molecule of IShine. A314 + IShine is a great established mix for me and I know I will be using that a lot when I work in a job environment for most of the day. No experimentation required for that one! I understand it well now so I am looking to explore other mixes. TAL + P74 seems like a great addition as of now.
