Human Sex Pheromone

can you actually buy pheromones?

if not what is something similar that you can buy?
im doing a study on how pheromones affect the human body since it is a part of attraction to another human of the opposite sex( or same)

Actually, there are quite a few commercially produced pheromone products, many of them very effective. Unfortunately, there are also alot of scammers too.

There are two really reliable sources for them...Love Scent and Androtics Direct. Love Scent sells most of the legitimate brands (and they are very good at ONLY selling legitimate brands). Androtics Direct makes its own stuff and is pretty much the best there is.

There is an active forum where people discuss their results with these. Pay special attention to the sticky posts at the top of each forum. They will bring you up to speed with which commerciall produced pheromones have what effects and what many of the products do (which tend to be various blends of pheromones for specific purposes):

If you want a little direct experience, Adrotics Direct makes small "togo" bottles of many of their products. They are inexpensive and hold about 40 sprays. Plenty to spend a few weeks testing out what they do. At about $14, I'd recommend Instant Sexiness. Read up on the forums what various women experience using that.

For a rather dramatic example, consider getting some Come Talk to Me 2. It's a pre-release formula of two "social" pheromones that make people comfortable talking and getting to know each other. But the formula is a bit too strong. You wear 4 or 5 sprays of that stuff and people around you just talk and talk and talk, babbling about anything and everything. The effect is just so obvious and incongruent with normal behavior. It makes a good demonstrations that pheromones have direct, and sometimes, quite strong effects.
