Why does Noopept cause headaches in some users?

Noopept accelerates synaptic transmission, rapidly consuming acetylcholine. If acetylcholine precursors (choline) are depleted, it causes a neurotransmitter shortage that manifests as a mild tension headache. Adding a bioavailable choline source resolves this immediately.
