Alpha-GPC
The VIP delivery of brain fuel — gets choline past the blood-brain barrier fast
High-bioavailability choline for focus.
The most bioavailable choline source. Crosses the blood-brain barrier and raises brain acetylcholine — the neurotransmitter of focus, attention, and learning.
- Stronger, more immediate effect than citicoline in most users.
- Can produce brain fog or headache if already choline-replete.
- Clinical interest in age-related cognitive decline and post-stroke recovery.
Your brain has a security gate called the blood-brain barrier — most supplements get stopped at the door. Alpha-GPC is special because it walks right through. Once inside, it delivers choline, which your brain turns into acetylcholine — the chemical you need for learning, memory, and focus. Think of it like a VIP pass that gets brain fuel straight to where it's needed. It's the most efficient choline source you can take, way better than regular choline supplements.
How long it stays, how it leaves.
Fixed dosing — not weight-adjusted. The calculator handles reconstitution math for common vial sizes so you inject the right volume every time.
Three tiers, three goals.
Take with food to avoid stomach issues

What people actually report.
- Headache (usually means your dose is too high)
- Heartburn or stomach upset
- Dizziness
- Fishy body odor at very high doses
Before you start.
- Most bioavailable choline source — much better absorbed than choline bitartrate
- If you get headaches, lower the dose — your brain might already have enough choline
- Take with food to avoid heartburn
- No tolerance buildup — works well long-term
