Comparison
Alpha-GPC vs Galantamine
Alpha-GPC
The most bioavailable common choline source. About 40% of an oral dose reaches the brain within an hour, where it serves as substrate for acetylcholine synthesis and as a phospholipid membrane component. The de facto pairing for every racetam stack.
Galantamine
Prescription cognitive enhancer derived from snowdrop. Selective AChE inhibitor + allosteric nicotinic potentiator.

Bottom line
Alpha-GPC (evidence A, safety 5/5) matches the evidence base of Galantamine (evidence A, safety 3/5). Alpha-GPC has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose Alpha-GPC if
Alpha-GPC is the better fit when your goal aligns with its mechanism (Rapidly absorbed and cleaved into choline and glycerophosphate) and the dose range (300–600mg) suits your protocol. Half-life is 6h.
Choose Galantamine if
Galantamine is the better fit when your goal aligns with its mechanism (Reversibly inhibits acetylcholinesterase like donepezil, but with the additional unique property of allosteric potentiation of nicotinic acetylcholine receptors) and the dose range (4–12mg) suits your protocol. Half-life is 7h.
