How do stimulants affect the brain and body?
Stimulants, such as dextroamphetamine and methylphenidate, have chemical structures similar to a family of key brain neurotransmitters called monoamines, which include norepinephrine and dopamine. Stimulants also increase blood pressure and heart rate, constrict blood vessels, increase blood glucose, and open up the pathways of the respiratory system.[Source]
"The entire process was very efficient and was handled in a very professional manner. The "process" was well thought out and the Test Country staff actually knew the process very well. I would not hesitate for a moment in using Test Country again if the need arose. Also the staff was extremely patient with me in explaining the "process". This was a brand new experience for me and I truly appreciated the help." (Ken N.)
