Synaptogenesis
Very low
Population: Animal models
Study type: Theoretical
Dose context: 20 mg typical

Dihexa is theorized to promote synaptogenesis through potentiation of HGF/Met signaling.

Citation: Theoretical based on known pharmacology.
No direct studies; based on mechanism of action.

Trade-offs & context
Neural

Narrow therapeutic window — excess AChE inhibition causes nausea, bradycardia, and muscle cramps

Interaction

Do not combine with Alpha-GPC, CDP-Choline, or other cholinergic supplements — risk of cholinergic toxicity

Timing

Must be cycled — accumulation occurs with daily use; standard protocol is 2 weeks on / 1 week off

Memory / cognitive performance
Moderate
Population: Older adults; Alzheimer's patients; healthy students
Study type: RCTs + meta-analyses (Chinese trials)
Dose context: — • Duration: 4–12 weeks with cycling

Reliable improvements in memory & executive function; strong AChE inhibition; cycle to avoid tolerance.

Citation: Li et al. 2008 (meta); Sun et al. 1999•https://pubmed.ncbi.nlm.nih.gov/20301721/
Cycle 2 weeks on / 1 week off. Avoid combining with other cholinergics.

Caution
Huperzine A: cycle required
Huperzine A accumulates — continuous daily use leads to tolerance and cholinergic excess. Cycle 2 weeks on / 1 week off. Do not combine with other acetylcholinesterase inhibitors.

Pre-check is rule-based, not medical advice. Consult a healthcare professional for personalised guidance.
