This drug allows for extreme concentration, putting all your focus on a single point and going for it without being distracted, by stimulating parts of the frontal lobe. It is very useful if you wish to do work, and work well and has a certain effect of negating the need for sleep and rest, again effecting certain areas of the brain. It can be abused and the takers body can simply wear out if this is taken over a prolonged amount of time (if the body does not rest enough, mentally they will be able to continue, and they will feel as if they can physically), and can burn the body out, as it begins to burn up muscle and fat that the body needs to function. If overdosed it can cause a need for more to maintain concentration.
The pheromone drugs take the form of 1 ½ long metal cylinder, with one smooth, rounded end, and another flat one. The pheromone drug can be either drunken, or injected, which it allows by a chemical in the concoction which makes cells extremely absorbent. As such if you press the cylinder to your arm (or whatever part of your body you wish), and press the rounded end, your arm will quickly absorb the chemical, it will quickly reach the blood stream and come into effect. It can also be drunken by unscrewing the flat end and simply drinking it, the fluid being absorbed in the mouth or when going down the throat. It is rare for any of it to reach the stomach.
In the capsules the amount of the pheromone is measured very specifically, and if taking just that capsule, there should not be any problems, taking more than that can cause serious difficulties.
