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.

Cognitive enhancement

Very low

Population: Animal models

Study type: Systematic review

Dose context: 20 mg typical

The systematic review suggests potential cognitive benefits of angiotensin IV and related compounds in animal models.

Citation: Ho et al. (2018). Cognitive benefits of angiotensin IV and angiotensin-(1-7): A systematic review of experimental studies. Neuroscience & Biobehavioral Reviews.•DOI: 10.1016/j.neubiorev.2018.05.005

No human studies available; findings are based on animal research.

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.
