Dihexa

An angiotensin IV analogue studied in rodent cognition research, with no human trials published.

What research shows

Every study we verified for dihexa is preclinical: procognitive and synaptogenic effects of angiotensin IV derived peptides in animal models, with a proposed hepatocyte growth factor mechanism described in reviews. No human trial exists in the literature searched, and no safety data in people.

Evidence strength

Highest evidence grade among the graded claims: C. Grades reflect study strength, not benefit.

Safety context

See the safety section. Absence of a flag is not evidence of safety.

No endorsement

A grade reflects evidence strength, not a recommendation to use this compound; a strong grade can attach to a harmful effect.
