Psycho

Psycho is a drug composed of strange and unknown chemicals of military origin(it is known that the base form of psycho is heroin), with a unique delivery system. It was designed at the orders of General Constantine Chase and is supposed to increase the combat potential of a soldier.

Psycho appears to be a form of injected drug, which, considering the large serum canister next to the needle, suggests that large quantities are needed to produce the effects. Apparently the evidence of the needle and two additional canisters(on of which is heroin) attached by wire to the hypodermic needle, seems to give evidence that psycho's chemicals must be mixed instantly and in large amounts before the injection into the body, otherwise the drug is worthless. in other lore of fallout it is said that the only remedy for psycho overdose is a shot of med-x in the the aorta of the heart possibly a references to real world heroin which only remedy for overdose is an injection of adrenaline to the heart.

Fallout, Fallout 2 and Fallout Tactics
Psycho has another beneficial effect not intended by the programmers. When taken, it reduces Intelligence by 3. This can be exploited to boost your skill points. First, raise a skill to the point it needs two skill points to be increased, then level up.

When you level up, take two to reduce your Intelligence greatly. This will correspondingly lower your skills involving Intelligence (Science, Repair, Outdoorsman, Doctor, etc). Now allocate your skill points to the skill you want raised - since the skill's value has been lowered, it will take only one skill point to do so. Then rest for a few hours. When the Psycho wears off, Intelligence will be restored, and the skill will be given a significant boost. This s particularly useful for getting a 121% Science skill to recruit Skynet without taking Mentats or wasting too many skill points.
