The less you know the person, the better the pheromone will work, because friends and aquaintences are already familiar with your natural pheromone siignature.
I suggest you start out with the big three (as Tisha calls them) Ammo (girl attractant, gives off a sexy vibe), Instant Shine (enhances confidence) and Instant Openness (promotes chattiness).
Start off testing each product solo. Spray yourself with a single spray and test over several days to see what happens each day. After you think you can understand the reactions, move up to teo sprays and test again. This way, you can learn your sweet spot, where you get the most hits without an OD (Opposite of Desired effect-- where people are avoiding you or being agitated by the extra pheromones.) After you find the sweet spot of each product, you can then layer (apply the correct number of sprays for each product while wearing more than one product at once) these products for even greater effect.
In a club environment where there is a lot of other distracting smells, you may well need to up your dosage of some pheromones. In a small room/house, you will want to pull back on your dosage.
Hope this helps!
