Alpha-GPC vs Pinealon
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Alpha-GPC is the most bioavailable form of choline, readily crossing the blood-brain barrier to rapidly increase acetylcholine levels. It enhances cognitive performance, supports GH secretion, and is used as an essential complement to many nootropic peptides (especially those that increase acetylcholine demand like Noopept and Dihexa).
- Pinealon is a synthetic tripeptide (Glu-Asp-Arg) developed by the St. Petersburg Institute of Bioregulation, designed to penetrate the blood-brain barrier and exert neuroprotective, neurogenic, and anti-aging effects by regulating pineal gland and brain cell function.
- Half-Life
- ~4–6 hours
- Short (peptides rapidly degraded), but epigenetic/gene regulatory effects persist
- Admin Route
