Dihexa

Dihexa is a synthetic compound derived from angiotensin IV, developed at Washington State University and studied as a procognitive agent acting through the hepatocyte growth factor and c-Met system. No human clinical trial of dihexa has been published.

What the research reports

Reported benefits of Dihexa

Outcomes described across the published Dihexa literature and ongoing study. Read each as research context rather than a promised personal result.

01
Synaptogenesis animal study
Animal work reports formation of new synaptic connections, which is the mechanism behind the procognitive claims made for this compound. Reported in research settings.
02
HGF and c-Met pathway work
Acts by activating the hepatocyte growth factor and c-Met receptor system, a pathway tied to neuronal survival and plasticity. Reported in research settings.
03
High laboratory potency data
Active at very low concentrations in cell based synaptogenesis assays, which is a measure of potency rather than of clinical effect. Reported in research settings.
04
Memory model animal study
Studied in animal models of impaired cognition, including scopolamine induced amnesia and Alzheimer's disease models. Described in the research record.
05
Neuroprotection study note
Reviews propose neuroprotective potential through the same growth factor pathway, though no controlled human data supports this. Reported in research settings.

Dosage and protocol

How Dihexa is typically studied

Protocols report 10 to 20 mg orally or 0.5 to 2 mg subcutaneously once daily. No human pharmacokinetic data supports these figures. Figures describe study protocols, not a personal regimen.

Route: Oral or subcutaneous
Example range: 10-20 mg oral
Frequency: Once daily
Timing: Morning dosing for cognitive protocols. Keep oral solution in amber glass.

Clinical evidence

Dihexa clinical evidence summary

The published Dihexa record, labeled by strength so you can see what is settled and what is still emerging.

Mechanism animal study 2014

An animal study reported that the procognitive and synaptogenic effects of angiotensin IV derived peptides depend on activation of the HGF and c-Met system. Reported in the cited paper.

Source

Huntington model study 2024

An animal study in 40 rats found that an angiotensin IV analogue did not protect against 3-nitropropionic acid induced Huntington's like symptoms. Reported in the cited paper.

Source

Systematic animal review 2018

A systematic review of experimental studies examined cognitive effects of angiotensin IV and angiotensin 1-7 across the available animal literature. Reported in the cited paper.

Interactions

How Dihexa pairs with other peptides

Semax peptide: Both are studied for cognition by separate mechanisms, with no data on combined administration.
c-Met inhibitors: Dihexa activates the pathway that these cancer drugs are designed to block, so the two directly oppose.
ACE inhibitors: Both touch the renin angiotensin system, so overlap is plausible but has not been formally studied.
Selank peptide: No published interaction data exists for this pairing in either the human or the animal literature.

Questions

Frequently asked questions.

What is Dihexa?

Dihexa is a peptide compound used in research settings. It is commonly studied for its role in cognitive, and many researchers compare supplier quality, purity, and testing data before purchasing.

What are the research benefits of Dihexa?

Dihexa is often evaluated for its potential influence on signaling pathways, recovery support, and targeted research applications. Research interest varies by peptide, formulation, and study design, so buyers typically review purity, dose, and independent lab verification before choosing a source.

How does Dihexa work?

Like other research peptides, Dihexa is typically studied for how it interacts with specific biological pathways and receptor systems. In practice, the way it is formulated, dosed, and tested matters as much as the compound itself, which is why verified suppliers and transparent COAs are important.

Is Dihexa for research use only?

Yes, products like Dihexa are generally intended for research, laboratory, or educational use and are not marketed as approved human therapeutics. Always follow local laws, lab safety practices, and institutional requirements before handling or studying any peptide.

What should I look for before buying Dihexa?

Key checks include verified COA data, peptide form and concentration, supplier reputation, stock status, and cost per mg. Comparing pricing and testing records side-by-side helps reduce the risk of buying an under-tested or misrepresented product.
