Quick Summary
An angiotensin IV analogue studied in rodents for effects on synapse formation, acting through hepatocyte growth factor and its receptor c-Met. There are no human trials of it. Available from 7 vendors, priced from $38.00 to $119.99.
Research: The seven-orders-of-magnitude potency comparison usually quoted for dihexa could not be pinned to a live primary paper. The main procognitive-analogue paper (McCoy et al 2013, PMID 23055539) contains no such comparison, and the mechanistic paper that established the synaptogenic effect (Benoist et al, J Pharmacol Exp Ther 2014;351(2):390-402, PMID 25187433) was RETRACTED in April 2025 after a 2021 expression of concern. All dihexa literature traces to a single laboratory, and the mechanism is HGF and c-Met potentiation rather than a direct BDNF pathway.
Side effects: No human data exists
Research compoundNo human trials of dihexa itself. Its central mechanistic paper was retracted in April 2025.
