Dihexa vs Humanin

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Dihexa

Dihexa is a nootropic peptide derived from angiotensin IV. It has shown remarkable cognitive-enhancing properties in animal studies, being described as potentially millions of times more potent than BDNF.

Side-by-Side Comparison

Aspect	Dihexa	Humanin
Dose Range	5 mg–20 mg	100 mcg–500 mcg
Frequency	1x daily	1x daily
Cycle Length	4–12 weeks	4–8 weeks
Route	oral	subcutaneous
Mechanism	Acts as a hepatocyte growth factor (HGF) potentiator by binding to its receptor c-Met. Promotes synaptogenesis, neuronal survival, and cognitive enhancement through this pathway.	Binds to IGFBP-3 and BAX, inhibiting apoptosis. Activates STAT3 signaling and enhances cellular survival under stress. Protects mitochondrial function and reduces oxidative stress.
Typical Dosage	Research dosing is highly variable due to extreme potency. Typical range: 10-40mg orally or sublingually. Start with lowest doses due to potency.	Research protocols vary widely. Studies have used doses from micrograms to milligrams depending on the analog and route. HNG (S14G-Humanin) is a more potent analog.
Administration	Can be taken orally, sublingually, or intranasally. Extremely potent - careful dosing is essential. Best used cyclically.	Subcutaneous or intraperitoneal injection in research. Various analogs exist with different potencies and stabilities.
Side Effects	Limited human data. Reported effects include headache, temporary brain fog during adjustment, and potential mood changes.	Limited human data. Generally well-tolerated in animal studies. May affect glucose metabolism.
