What it is
A racetam that acts on metabotropic glutamate receptors and GABA-B. It was trialled for vascular dementia, then for ADHD in teens with certain glutamate-receptor gene variants.
How it helps
Calm focus and mood. Some people use it to soften the comedown from stimulants.
What to watch for
Human studies are small and open-label. Headache and tiredness are reported.
These are compounds to research, not a protocol to copy. Education and my opinion, not medical advice. Talk to a doctor, especially before combining anything with prescription medication. Shop links are affiliate links: tapping one opens the store and copies my code.
