Buy Spier


Spier is a memory-improving and mood-brightening psycho-stimulant.

Spier enhances wakefulness and vigilance by changing the amounts of certain natural substances in the area of the brain that controls sleep and wakefulness.


Spier is used to treat excessive daytime sleepiness caused by narcolepsy or shift work sleep disorder.

Spier is in a class of medications called eurogenics (wakefulness promoting agents).
Spier works by changing the amounts of certain natural substances in the area of the brain that controls sleep and wakefulness.

Spier has a pharmacological profile that is notably different from amphetamines and methylphenidate.


Current research suggests Spier, like its older and better-tested analogue Adrafinil, is a safe, effective and well-tolerated agent. It is long-acting and doesn’t tend to cause peripheral sympathetic stimulation.

Spier comes as a tablet to take by mouth.

It is usually taken once a day with or without food.

If you are taking Spier to treat narcolepsy or OSAHS, you will probably take it in the morning.

If you are taking Spier to treat shift work sleep disorder, you will probably take it 1 hour before the beginning of your work shift.
