Stacking guide
What goes well with CDP-Choline?
Evidence-graded stacking partners for CDP-Choline. Synergistic and neutral combinations are listed alongside pairings to avoid. Use this to design a deliberate stack rather than experimenting blind.
Safe to stack with CDP-Choline (4)
- PiracetamEVIDENCEA
The original nootropic, developed in 1964 by Romanian chemist Corneliu Giurgea. A cyclic derivative of GABA and the founding member of the racetam family.
Alternative cholinergic pairing for racetams.
- AniracetamEVIDENCEB
A fat-soluble racetam ~5-10x more potent than piracetam. Anxiolytic and creativity-enhancing.
Common substitution for Alpha-GPC.
- OxiracetamEVIDENCEB
Water-soluble racetam known for analytical focus and logical reasoning enhancement.
Common substitution.
- NoopeptEVIDENCEB
Russian-developed proline-containing dipeptide ~1000x more potent than piracetam by weight. Often grouped with racetams.
Common substitution.
Combine with caution (1)
- Huperzine AEVIDENCEA
Potent acetylcholinesterase inhibitor derived from Chinese club moss. Studied for Alzheimer's treatment in China.
Same caution as Alpha-GPC — cholinergic overstack.
Build a stack: use the Stack Builder with CDP-Choline pre-selected, or check any specific pairing in the Interaction Checker.
Stacking guidance reflects curated interaction rules from the published literature, traditional use, and well-characterised mechanisms. Individual response varies; introduce one substance at a time and track effects. Not medical advice — see our disclaimer.
