How it works
KapvayDesoxyn
Clonidine is an alpha-2 agonist. Researchers don't know exactly how it works for ADHD. It works in the brain and lowers the activity of certain stress hormones, but it's not a stimulant like many ADHD medicines.Desoxyn (Methamphetamine) is a stimulant. It treats attention-deficit/hyperactivity disorder (ADHD) and weight loss by increasing norepinephrine and dopamine activity in the brain.
