WebAmfetamines cause release of noradrenaline (norepinephrine), dopamine and serotonin from presynaptic terminals, as opposed to having direct agonist effects on postsynaptic receptors. Pharmacokinetics. Amfetamines have a very short biological life in humans and reach higher concentrations in the brain than in blood. WebMeth does not directly release dopamine. It attaches itself to dopamine receptor sites and fools neurons into releasing large quantities of dopamine. This accounts for the intense …
