However its not listed in store so its probably out of stock even though the thread link shows 30 available. I would check first with AD.
If its not in stock tell us what your intentions are for pheromones. What you would like them to do for you and acheive with them and we will point you to where to start.
Do not start with advanced products like the putatives, P83, P102 etc etc… These are for experienced users.
